Signal-, set- and movement-related activity in the human brain: an event-related fMRI study. (1/9774)Electrophysiological studies on monkeys have been able to distinguish sensory and motor signals close in time by pseudorandomly delaying the cue that instructs the movement from the stimulus that triggers the movement. We have used a similar experimental design in functional magnetic resonance imaging (fMRI), scanning subjects while they performed a visuomotor conditional task with instructed delays. One of four shapes was presented briefly. Two shapes instructed the subjects to flex the index finger; the other two shapes coded the flexion of the middle finger. The subjects were told to perform the movement after a tone. We have exploited a novel use of event-related fMRI. By systematically varying the interval between the visual and acoustic stimuli, it has been possible to estimate the significance of the evoked haemodynamic response (EHR) to each of the stimuli, despite their temporal proximity in relation to the time constant of the EHR. Furthermore, by varying the phase between events and image acquisition, we have been able to achieve high temporal resolution while scanning the whole brain. We dissociated sensory and motor components of the sensorimotor transformations elicited by the task, and assessed sustained activity during the instructed delays. In calcarine and occipitotemporal cortex, the responses were exclusively associated with the visual instruction cues. In temporal auditory cortex and in primary motor cortex, they were exclusively associated with the auditory trigger stimulus. In ventral prefrontal cortex there were movement-related responses preceded by preparatory activity and by signal-related activity. Finally, responses associated with the instruction cue and with sustained activity during the delay period were observed in the dorsal premotor cortex and in the dorsal posterior parietal cortex. Where the association between a visual cue and the appropriate movement is arbitrary, the underlying visuomotor transformations are not achieved exclusively through frontoparietal interactions. Rather, these processes seem to rely on the ventral visual stream, the ventral prefrontal cortex and the anterior part of the dorsal premotor cortex. (+info)
Cerebellar Purkinje cell simple spike discharge encodes movement velocity in primates during visuomotor arm tracking. (2/9774)Pathophysiological, lesion, and electrophysiological studies suggest that the cerebellar cortex is important for controlling the direction and speed of movement. The relationship of cerebellar Purkinje cell discharge to the control of arm movement parameters, however, remains unclear. The goal of this study was to examine how movement direction and speed and their interaction-velocity-modulate Purkinje cell simple spike discharge in an arm movement task in which direction and speed were independently controlled. The simple spike discharge of 154 Purkinje cells was recorded in two monkeys during the performance of two visuomotor tasks that required the animals to track targets that moved in one of eight directions and at one of four speeds. Single-parameter regression analyses revealed that a large proportion of cells had discharge modulation related to movement direction and speed. Most cells with significant directional tuning, however, were modulated at one speed, and most cells with speed-related discharge were modulated along one direction; this suggested that the patterns of simple spike discharge were not adequately described by single-parameter models. Therefore, a regression surface was fitted to the data, which showed that the discharge could be tuned to specific direction-speed combinations (preferred velocities). The overall variability in simple spike discharge was well described by the surface model, and the velocities corresponding to maximal and minimal discharge rates were distributed uniformly throughout the workspace. Simple spike discharge therefore appears to integrate information about both the direction and speed of arm movements, thereby encoding movement velocity. (+info)
Complete compensation in skilled reaching success with associated impairments in limb synergies, after dorsal column lesion in the rat. (3/9774)Each of the dorsal columns of the rat spinal cord conveys primary sensory information, by way of the medullary dorsal column nucleus, to the ventrobasal thalamus on the contralateral side; thus the dorsal columns are an important source of neural input to the sensorimotor cortex. Damage to the dorsal columns causes impairments in synergistic proximal or whole-body movements in cats and distal limb impairments in primates, particularly in multiarticulated finger movements and tactile foviation while handling objects, but the behavioral effects of afferent fiber lesions in the dorsal columns of rodents have not been described. Female Long-Evans rats were trained to reach with a forelimb for food pellets and subsequently received lesions of the dorsomedial spinal cord at the C2 level, ipsilateral to their preferred limb. Reaching success completely recovered within a few days of dorsal column lesion. Nevertheless, a detailed analysis of high-speed video recordings revealed that rotatory limb movements (aiming, pronation, supination, etc.) were irreversibly impaired. Compensation was achieved with whole-body and alternate limb movements. These results indicate the following: (1) in the absence of the dorsal columns, other sensorimotor pathways support endpoint success in reaching; (2) sensory input conveyed by the dorsal columns is important for both proximal and distal limb movements used for skilled reaching; and (3) detailed behavioral analyses in addition to endpoint measures are necessary to completely describe the effects of dorsal column lesions.

Behavioral, toxic, and neurochemical effects of sydnocarb, a novel psychomotor stimulant: comparisons with methamphetamine. (4/9774)Sydnocarb (3-(beta-phenylisopropyl)-N-phenylcarbamoylsydnonimine) is a psychostimulant in clinical practice in Russia as a primary and adjunct therapy for a host of psychiatric disorders, including schizophrenia and depression. It has been described as a stimulant with an addiction liability and toxicity less than that of amphetamines. The present study undertook to evaluate the psychomotor stimulant effects of sydnocarb in comparison to those of methamphetamine. Sydnocarb increased locomotor activity of mice with reduced potency (approximately 10-fold) and efficacy compared with methamphetamine. Sydnocarb blocked the locomotor depressant effects of haloperidol at doses that were inactive when given alone. The locomotor stimulant effects of both methamphetamine and sydnocarb were dose-dependently blocked by the dopamine D1 and D2 antagonists SCH 39166 and spiperone, respectively; blockade generally occurred at doses of the antagonists that did not depress locomotor activity when given alone. In mice trained to discriminate methamphetamine from saline, sydnocarb fully substituted for methamphetamine with a 9-fold lower potency. When substituted for methamphetamine under self-administration experiments in rats, 10-fold higher concentrations of sydnocarb maintained responding by its i.v. presentation. Sydnocarb engendered stereotypy in high doses with approximately a 2-fold lower potency than methamphetamine. However, sydnocarb was much less efficacious than methamphetamine in inducing stereotyped behavior. Both sydnocarb and methamphetamine increased dialysate levels of dopamine in mouse striatum; however, the potency and efficacy of sydnocarb was less than methamphetamine. The convulsive effects of cocaine were significantly enhanced by the coadministration of nontoxic doses of methamphetamine but not of sydnocarb. Taken together, the present findings indicate that sydnocarb has psychomotor stimulant effects that are shared by methamphetamine while demonstrating a reduced behavioral toxicity. (+info)
Evidence for an eye-centered spherical representation of the visuomotor map. (5/9774)During visually guided movement, visual coordinates of target location must be transformed into coordinates appropriate for movement. To investigate the representation of this visuomotor coordinate transformation, we examined changes in pointing behavior induced by a local visuomotor remapping. The visual feedback of finger position was limited to one location within the workspace, at which a discrepancy was introduced between the actual and visually perceived finger position. This remapping induced a change in pointing that extended over the entire workspace and was best captured by a spherical coordinate system centered near the eyes. (+info)
Visuomotor processing as reflected in the directional discharge of premotor and primary motor cortex neurons. (6/9774)Premotor and primary motor cortical neuronal firing was studied in two monkeys during an instructed delay, pursuit tracking task. The task included a premovement "cue period," during which the target was presented at the periphery of the workspace and moved to the center of the workspace along one of eight directions at one of four constant speeds. The "track period" consisted of a visually guided, error-constrained arm movement during which the animal tracked the target as it moved from the central start box along a line to the opposite periphery of the workspace. Behaviorally, the animals tracked the required directions and speeds with highly constrained trajectories. The eye movements consisted of saccades to the target at the onset of the cue period, followed by smooth pursuit intermingled with saccades throughout the cue and track periods. Initially, an analysis of variance (ANOVA) was used to test for direction and period effects in the firing. Subsequently, a linear regression analysis was used to fit the average firing from the cue and track periods to a cosine model. Directional tuning as determined by a significant fit to the cosine model was a prominent feature of the discharge during both the cue and track periods. However, the directional tuning of the firing of a single cell was not always constant across the cue and track periods. Approximately one-half of the neurons had differences in their preferred directions (PDs) of >45 degrees between cue and track periods. The PD in the cue or track period was not dependent on the target speed. A second linear regression analysis based on calculation of the preferred direction in 20-ms bins (i.e., the PD trajectory) was used to examine on a finer time scale the temporal evolution of this change in directional tuning. The PD trajectories in the cue period were not straight but instead rotated over the workspace to align with the track period PD. Both clockwise and counterclockwise rotations occurred. The PD trajectories were relatively straight during most of the track period. The rotation and eventual convergence of the PD trajectories in the cue period to the preferred direction of the track period may reflect the transformation of visual information into motor commands. The widely dispersed PD trajectories in the cue period would allow targets to be detected over a wide spatial aperture. The convergence of the PD trajectories occurring at the cue-track transition may serve as a "Go" signal to move that was not explicitly supplied by the paradigm. Furthermore, the rotation and convergence of the PD trajectories may provide a mechanism for nonstandard mapping. Standard mapping refers to a sensorimotor transformation in which the stimulus is the object of the reach. Nonstandard mapping is the mapping of an arbitrary stimulus into an arbitrary movement. The shifts in the PD may allow relevant visual information from any direction to be transformed into an appropriate movement direction, providing a neural substrate for nonstandard stimulus-response mappings.

Visual control of locomotion in Parkinson's disease. (7/9774)The effect of placing parallel lines on the walking surface on parkinsonian gait was evaluated. To identify the kind of visual cues (static or dynamic) required for the control of locomotion, we tested two visual conditions: normal lighting and stroboscopic illumination (three flashes/s), the latter acting to suppress dynamic visual cues completely. Sixteen subjects with idiopathic Parkinson's disease (nine males, seven females; mean age 68.8 years) and the same number of age-matched controls (seven males; nine females, mean age 67.5 years) were studied. During the baseline phase, Parkinson's disease patients walked with a short-stepped, slow velocity pattern. The double limb support duration was increased and the step cadence was reduced relative to normal. Under normal lighting, visual cues from the lines on the walking surface induced a significant improvement in gait velocity and stride length in Parkinson's disease patients. With stroboscopic illumination and without lines, both groups reduced their stride length and velocity but the changes were significant only in the Parkinson's disease group, indicating greater dependence on dynamic visual information. When stroboscopic light was used with stripes on the floor, the improvement in gait due to the stripes was suppressed in parkinsonian patients. These results demonstrate that the perceived motion of stripes, induced by the patient's walking, is essential to improve the gait parameters and thus favour the hypothesis of a specific visual-motor pathway which is particularly responsive to rapidly moving targets. Previous studies have proposed a cerebellar circuit, allowing the visual stimuli to by-pass the damaged basal ganglia. (+info)
Common 3 and 10 Hz oscillations modulate human eye and finger movements while they simultaneously track a visual target. (8/9774)1. A 10 Hz range centrally originating oscillation has been found to modulate slow finger movements and anticipatory smooth eye movements. To determine if an interaction or linkage occurs between these two central oscillations during combined visuo-manual tracking, frequency and coherence analysis were performed on finger and eye movements while they simultaneously tracked a visual target moving in intermittently visible sinusoidal patterns. 2. Two different frequencies of common or linked oscillation were found. The first, at 2-3 Hz, was dependent on visual feedback of target and finger tracking positions. The second, at around 10 Hz, still occurred when both target and finger positions were largely obscured, indicating that this common oscillation was generated internally by the motor system independent of visual feedback. Both 3 and 10 Hz oscillation frequencies were also shared by the right and left fingers if subjects used these together to track a visual target. 3. The linking of the 10 Hz range oscillations between the eyes and finger was task specific; it never occurred when eye and finger movements were made simultaneously and independently, but only when they moved simultaneously and followed the target together. However, although specific for tracking by the eyes and fingers together, the linking behaviour did not appear to be a prerequisite for such tracking, since significant coherence in the 10 Hz range was only present in a proportion of trials where these combined movements were made. 4. The experiments show that common oscillations may modulate anatomically very distinct structures, indicating that single central oscillations may have a widespread distribution in the central nervous system. The task-specific manifestation of the common oscillation in the eye and finger suggests that such mechanisms may have a functional role in hand-eye co-ordination. (+info)
ERIC - The Effects of Aging on Motor Performance., 1982
A review of research on the effects of aging on motor performance provided evidence that age-induced changes within the central nervous system, particularly in the functioning of the non-dominant cortical hemisphere, result in diminished fluid abilities. The loss was most clearly manifested behaviorally as a decreased capacity to perform high-speed, extrinsically-paced motor skills. A study assessed the effects of aging on the performance of intrinsically- and extrinsically-paced motor skills. Seventy-nine subjects (58 females and 21 males) were divided into three groups based on age: 60-65; 65-70; and over 70. Four criterion tasks were assigned: (1) pursuit rotor tracking; (2) mirror tracing; (3) visual choice reaction time; and (4) limb positioning. No significant differences in performance were observed among the three age groups on any of the tasks. There were significant differences between males and females for rotary pursuit tracking at all speeds. There were no significant

Faculty Collaboration Database - Functionally distinct regions for spatial processing and sensory motor integration in the...
There has been much debate recently over the functional role played by the planum temporale (PT) within the context of the dorsal auditory processing stream. Some studies indicate that regions in the PT support spatial hearing and other auditory functions, whereas others demonstrate sensory-motor response properties. This multifunctionality has led to the claim that the PT is performing a common computational pattern matching operation, then routing the signals (spatial, object, sensory-motor) into an appropriate processing stream. An alternative possibility is that the PT is functionally subdivided with separate regions supporting various functions. We assess this possibility using a within subject fMRI block design. DTI data were also collected to examine connectivity. There were four auditory conditions: stationary noise, moving noise, listening to pseudowords, and shadowing pseudowords (covert repetition). Contrasting the shadow and listen conditions should activate regions specific to ...

Card, English, and Burr (1978) - 25 Years Later
Target width in 2D. Card, English and Burr interpreted target width as the horizontal extent of the targets. The 5th and 6th columns recalculate ID using the smaller of the targets width and height as W. The rationale is that for rectangular targets selected in 2D, the smaller dimension is more indicative of the accuracy demands of the task . ID formula. ID was measured using the Welford formulation, whereas ISO9241-9 uses the Shannon formulation (Table 1 footnotes). Among the benefits in the latter is that ID cannot be negative. So the easiest task changes from -0.14 bits to 1.67 bits (Table 1 top row). Treatment of errors. Although Card et al. reported an error rate of 5% for the mouse condition, their Fitts law model excluded error trials [1, p. 605]. This precludes a post hoc adjustment for accuracy. TP formula.

Habilidades psicolinguísticas e escolares em crianças com mielomeningocele
The results obtained by the participants of G1 and G2, in the Rapid Automatized Naming Test (RAN), had shown that G1 presented a higher maximum value than the minimum value obtained by G2, confirming the difference between the groups. In relation to the subtests, G1 presented better scores in the rapid automatized naming test of objects, digits, letters and colors, respectively (Table 5). DISCUSSION. The reception of stimuli involves complex processes initiated through mechanisms of attention. Several are the implications of the difficulties in the receptive process; among them we find the difficulty to learn information and to associate them with other stimuli, or even to learn verbal and not verbal concepts(12,21,24). The same can be observed for the abilities of AA, VA and GC. These tests relate to the performance of the perceptive abilities. The perceptive development depends on the quality of the sensory motor experiences lived by the child, of its elaboration and organization, in addition ...

The experiments presented here sought to determine whether the learning of a visuomotor transformation, specifically a 30° rotation, undergoes a process of consolidation whereby learning becomes resistant to interference. In the first experiment, we found that interference with the 30° rotation by a 30° counter-rotation persisted even when adaptation to the counter-rotation occurred a full 24 hr later. This result is consistent with the position that consolidation does not occur for kinematic transformations (Bock et al., 2001; Goedert and Willingham, 2002; Miall et al., 2004; Robertson et al., 2004). However, in experiment 2, when we introduced washout blocks between rotations, resistance to interference was seen after 24 hr but not after 5 min. In our third experiment, when we doubled the amount of initial rotation training, we found resistance to interference by a counter-rotation even at 5 min.

Just Do Something - Your guide to getting things done
The most productive people do not just plan to do something. They get it done. And it is the execution or follow-through part that bridges goals to intended results. This is where many people get off track. So how do you translate talk to action? Sometimes the trick is to start by just doing something. Or to be more specific, to just do something, anything, related to your goals to start building your momentum. Focus on your most important goals. Everyone has a finite amount of time every day to accomplish things. Having too many goals that branch out to even more sub-goals or mini-goals make it near impossible to accomplish all the things you may think you need to do. Getting the results you want requires choosing your priorities well and focusing on the most important things related to your priority goals. Build momentum by doing one thing at a time. Multitasking may seem like you are accomplishing a lot of things at once. But it is does not guarantee that you will be productive. It may even ...

Motor Cortex Neurons Directly Influence Motor Output
... Science 6 November 2015: Vol. 350 no. 6261 pp. 667-670. Corticomotoneuronal cells are functionally tuned Darcy M. Griffin, et.al.. University of Pittsburgh Brain Institute, Center for the Neural Basis of Cognition and Systems Neuroscience Institute, Pittsburgh, PA, USA. Department of Neurobiology, University of Pittsburgh School of Medicine, Pittsburgh, PA, USA. Research Service, Department of Veterans Affairs Medical Center, Pittsburgh, PA, USA. [paraphrase]. Corticomotoneuronal (CM) cells in the primary motor cortex (M1) have monosynaptic connections with motoneurons. They are one of the few sources of descending commands that directly influence motor output. We examined the contribution of CM cells to the generation of activity in their target muscles. The preferred direction of many CM cells differed from that of their target muscles. Some CM cells were selectively active when a muscle was used as an agonist. Others were selectively ...
Effects of Number and Method of Visual Stimuli on Simple Reaction Time
In. order to evaluate the effects of number and method of visual stimuli on simple reaction time and determine the proper number of trials, simple reaction time of the computerized test of NTOS (Neurobehavioral Test for Occupational Screening) was carried out on 240 medical students. The prominent difference was found between male and female on simple reaction time. Regarding the effect of number based on the parameters of measures and the purpose of test itself, 64 trials was considered as proper number. The mean reaction time was different according to the methods of visual stimuli, such as color and size( ...
Attention to movement modulates activity in sensori-motor areas, including primary motor cortex. - Wellcome Centre for...
Attention to sensory stimulation modulates behavioural responses and cortical activity. Attention to movement can also modulate motor responses. For example, directing attention away from cued movements can increase reaction times. This study used fMRI to determine where in the motor cortex attention to movement modulates activity. Attention to movement was reduced by asking subjects to perform a concurrent distractor task (counting backwards). Sensori-motor areas showing a negative interaction between counting and movement (i.e. reduced activation in the dual task condition relative to the sum of the single task conditions) included the supplementary motor area (SMA), cingulate cortex, insula and post-central gyrus. A separate volumes-of-interest analysis revealed significant reductions in mean percent signal change in the dual task compared to the single task in a portion of the pre-central gyrus, deep in the central sulcus (thought to correspond to area 4p) and SMA. We conclude that the brain network
Feature interactions enable decoding of sensorimotor transformations for goal-directed movement | www.icb.ucsb.edu
Neurophysiology and neuroimaging evidence shows that the brain represents multiple environmental and body-related features to compute transformations from sensory input to motor output. However, it is unclear how these features interact during goal-directed movement. To investigate this issue, we examined the representations of sensory and motor features of human hand movements within the left-hemisphere motor network. In a rapid event-related fMRI design, we measured cortical activity as participants performed right-handed movements at the wrist, with either of two postures and two amplitudes, to move a cursor to targets at different locations. Using a multivoxel analysis technique with rigorous generalization tests, we reliably distinguished representations of task-related features (primarily target location, movement direction, and posture) in multiple regions. In particular, we identified an interaction between target location and movement direction in the superior parietal lobule, which may ...
A dissociation between stopping and switching actions following a lesion of the pre-supplementary motor area. - Wellcome Centre...
INTRODUCTION: Although the pre-supplementary motor area (pre-SMA) is one of the most frequently reported areas of activation in functional imaging studies, the role of this brain region in cognition is still a matter of intense debate. Here we present a patient with a focal lesion of caudal pre-SMA who displays a selective deficit in updating a response plan to switch actions, but shows no impairment when required to withhold a response - stopping. MATERIALS & METHODS: The patient and a control group underwent three tasks designed to measure different aspects of cognitive control and executive function. RESULTS: The pre-SMA patient displayed no impairment when responding in the face of distracting stimuli (Eriksen flanker paradigm), or when required to halt an on-going response (STOP task). However, a specific deficit was observed when she was required to rapidly switch between response plans (CHANGE task). CONCLUSIONS: These findings suggest that the caudal pre-SMA may have a particularly important
Posterior parietal cortex role in a sensorimotor task performance
The posterior parietal cortex (PPC) plays a crucial role in relation to motor planning based on sensory information. Human functional magnetic resonance imaging (fMRI) experiments and electrophysiological recordings in nonhuman primates have shown that the PPC is neither sensory nor motor purely, but it is an area that encodes cognitive functions related to action1,2. The presence of sensory and motor specific representations together with high-level cognitive signals suggests that the PPC plays an important role for decision making related to action2. Such representations are elementary components in the preparation and adjustment of a motor act and they take part in the integration among different and specialized centers in the final movement production3. This process occurs through sensorimotor integration, when sensory information is integrated by central nervous system to attend to motor programs. Catching an object is a complex movement which involves not only programming but also ...
Short-term plasticity of the visuomotor map during grasping movements in humans.
Sensorimotor transformations are processes whereby sensory information is used to generate motor commands. One example is the visuomotor map that transforms visual information about objects to motor commands that activates various muscles during grasping movements. In the first study we quantified the relative impact (or weighting) of visual and haptic information on the sensorimotor transformation and investigated the principles that regulates the weighting process. To do this, we let subjects perform a task in which the object seen (visual object) and the object grasped (haptic object) were physically never the same. When the haptic object became larger or smaller than the visual object, subjects in the following trials automatically adapted their maximum grip aperture (MGA) when reaching for the object. The adaptation process was quicker and relied more on haptic information when the haptic objects increased in size than when they decreased in size. As such, sensory weighting is molded ...

Frontiers | Efficient multitasking: parallel versus serial processing of multiple tasks | Psychology
In the context of performance optimizations in multitasking, a central debate has unfolded in multitasking research around whether cognitive processes related to different tasks proceed only sequentially (one at a time), or can operate in parallel (simultaneously). This review features a discussion of theoretical considerations and empirical evidence regarding parallel versus serial task processing in multitasking. In addition, we highlight how methodological differences and theoretical conceptions determine the extent to which parallel processing in multitasking can be detected, to guide their employment in future research. Parallel and serial processing of multiple tasks are not mutually exclusive. Therefore, questions focusing exclusively on either task-processing mode are too simplified. We review empirical evidence and demonstrate that shifting between more parallel and more serial task processing critically depends on the conditions under which multiple tasks are performed. We conclude that

[email protected]: On the neuronal processing of movement dynamics
The thesis collects five essays on how neurons in four motor areas of the frontal lobe process the movement dynamics. In the experiments described, monkeys executed visually instructed reaching movements while holding the handle of a robotic arm. Motors attached to the robot allowed turning on and off perturbing forces that deviated the hand of the monkeys. After some exposure, the monkeys adapted to the perturbation. The experiments were designed to dissociate the activity related to the desired kinematics from that related to the dynamics. Furthermore, the experiments dissociated the activity related to motor performance (desired kinematics and dynamics) from that related to motor learning (learning a new dynamics). The thesis describes the following results. 1. During motor execution, the movement dynamics is processed across multiple areas. Specifically, dynamics-related activity is found in all areas projecting to the spinal cord under study, namely the primary motor cortex (M1), ...

The influence of time preparation on motor processes assessed by surface Laplacian estimation - Open Access Repository
A distinct dimension of cognitive control is the ability to anticipate changes and prepare for behavioral adjustment. In a previous work, we combined computational modeling and fMRI of a stop signal task to characterize the neural processes linking conflict anticipation, an estimate of the likelihood of an upcoming stop signal or p(Stop) and go trial reaction time (GoRT). An increase in p(Stop) predicted a prolonged GoRT. We showed that activity to conflict anticipation in the presupplementary motor area (pre-SMA) Granger caused activity in the posterior pre-SMA, and bilateral anterior insula during go response slowing (Hu et al., 2015). Along with other studies, the latter work characterized the neural circuits for proactive control (Jaffard et al., 2008; Jahfari et al., 2010; Grinband et al., 2011; Criaud et al., 2012; Zandbelt et al., 2013; van Belle et al., 2014; Behan et al., 2015)..

The Effects of Trajectory and Endpoint Errors in a Reaching Movement on the Sense of Agency
The sense of agency (SoA) refers to the subjective feeling that an individual can control their own action with their own will. However, it is still unclear which aspects of the motor control process precisely affect the sense of agency. In this study, we investigated how the SoA is modulated by the online motor performance (trajectory error) and the outcome of the reaching movement (endpoint error). The results showed that the invalid priming and the visual feedback delay significantly increased both the trajectory and endpoint errors and that these errors significantly attenuated the SoA. The further correlation analyses showed that the decrease in SoA was significantly correlated with the trajectory error, but not with the endpoint error, when the error was explicitly noticed. We suggest that the deterioration in online motor performance, at least in a reaching movement, is the main cause of the attenuation in the SoA.
New Findings Help Explain the Dynamics Between The Dominant and Non-Dominant Arm
The transfer of a skill learned in one hand to the other hand has been used as evidence for the role of the brains hemispheres in controlling that skill. The movement of knowledge from the dominant to the nondominant arm (D ->ND) has been interpreted as confirmation of the brains ability to encode an experience in the dominant hemisphere with the dominant hand and to influence the performance of the nondominant hand. Many researchers believe that this process is accomplished either through connections across both hemispheres or through the same side of the brain. Other scientists believe that transfer in the opposite direction reflects a dominance of the right hemisphere (in right-handers) for some aspects of motor control, so both directions of transfer can be explained with a single model ...

The integration of cortical and behavioural dynamics during initial learning of a motor task. - Oxford Neuroscience
Here we test the hypothesis that frequency and topographically specific changes in the strength of functional cortico-cortical coupling occur during the acquisition of a completely new task. To this end we studied the behavioural and cortical dynamics of a bimanual multifrequency coordination pattern during which one hand moved at twice the frequency of the other hand. This pattern represents a noninherent assignment and necessitates training before appropriate interlimb decoupling takes place. Results showed that acquisition of the multifrequency task was associated with an improved behavioural output that matched specific changes in the electroencephalogram dynamics. In particular, practice of the coordination pattern was accompanied by a decrease in coherence between the primary sensorimotor regions, and over the midline area in the alpha and beta bands, respectively, along with an increase in functional interhemispheric coupling between the prefrontal areas in the gamma band. These data suggest that
Extending Fitts' law to two-dimensional tasks
The W model, although slightly more difficult to apply, performed as well as the SMALLER-OF model in Figure 7. The model assumes that subjects move toward the centre of the target. No doubt, behavioural optimization would follow under extreme conditions, such as selecting a "very wide" target at close range. If the starting point is below at 45°, for example, movement distances could be reduced by advancing along a more direct path. Such extremes were not tested. To prevent biasing the comparisons for any one model, the experiment fully crossed the three approach angles with all A-W-H conditions; thus, the minimum amplitude for each condition could be applied at each approach angle. Conditions such as A = 2.0 cm and W = 6 cm (as used by Gillan et al., ) preclude the possibility of θA = 0° since the starting position would be inside the target (see Figure 1). In fact, the designs employed by Card et al.  and Gillan et al.  would have provided even stronger evidence for the W and ...

A batch-to-batch optimal iterative learning control (ILC) strategy for the tracking control of product quality in batch processes is presented. The linear time-varying perturbation (LTVP) model is built for product quality around the nominal trajectories. To address problems of model-plant mismatches, model prediction errors in the previous batch run are added to the model predictions for the current batch run. Then tracking error transition models can be built, and the ILC law with direct error feedback is explicitly obtained. A rigorous theorem is proposed, to prove the convergence of tracking error under ILC. The proposed methodology is illustrated on a typical batch reactor and the results show that the performance of trajectory tracking is gradually improved by the ILC ...

In the late 1960s Charles Tart began the first laboratory tests with subjects who could have OBEs voluntarily [Tar67, 68]. In addition to his physiological research he also tested subjects ability to see a target hidden from their normal sight. His first subject, Miss Z., was tested in a laboratory where a target was placed on a shelf about five and a half feet above the bed where she lay. The target was a five-digit number prepared in advance by Tart and placed on the shelf. Miss Z. slept in the laboratory on four occasions. On the first she had no OBE; on the second, she managed to get high enough to see the clock, and on third night she had an OBE but traveled elsewhere. However, on her fourth and last night she awoke and reported that she had seen the number and it was 25132. She was right on all five digits which has a probability of only one in 100,000 of being right by chance. Tart himself seemed reluctant to conclude that it was paranormal.

- Impaired attention, memory, and psychomotor performance while intoxicated. (healthyplace.com)
- This research presents a new aggression regulation intervention for individuals with eating disorders (ED). The intervention, developed in psychomotor therapy (PMT), contributes to the need to treat anger and aggression problems in patients with ED, particularly excessive anger internalization. (rgoc.nl)
- The next morning they are awakened and are escorted to the exam room for the performance trial, which includes a quiz on the lecture and reading material, a GRE examination, the NES3 battery and the PVT. (clinicaltrials.gov)
- Some states integrate the EMR psychomotor exam into the EMR course. (nremt.org)
- Candidates should contact their State EMS Office or course instructor for guidance on their local psychomotor exam requirements. (nremt.org)
- Ethanol also impaired psychomotor performance and memory. (nature.com)
- No major psychomotor changes were observed, except on the short-term memory task, which appeared to reflect motivational factors. (dtic.mil)
- Working memory performance is thought to depend on both striatal dopamine 2/3 receptors (D2/3Rs) and task-induced functional organisation in key cortical brain networks. (bioportfolio.com)
