Evidence for an eye-centered spherical representation of the visuomotor map. (1/4172)

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)

Why and how is soft copy reading possible in clinical practice? (2/4172)

The properties of the human visual system (HVS) relevant to the diagnostic process are described after a brief introduction on the general problems and advantages of using soft copy for primary radiology interpretations. At various spatial and temporal frequencies the contrast sensitivity defines the spatial resolution of the eye-brain system and the sensitivity to flicker. The adaptation to the displayed radiological scene and the ambient illumination determine the dynamic range for the operation of the HVS. Although image display devices are determined mainly by state-of-the-art technology, analysis of the HVS may suggest technical characteristics for electronic displays that will help to optimize the display to the operation of the HVS. These include display size, spatial resolution, contrast resolution, luminance range, and noise, from which further consequences for the technical components of a monitor follow. It is emphasized that routine monitor quality control must be available in clinical practice. These image quality measures must be simple enough to be applied as part of the daily routine. These test instructions might also serve as elements of technical acceptance and constancy tests.  (+info)

Differential spatial memory impairment after right temporal lobectomy demonstrated using temporal titration. (3/4172)

In this study a temporal titration method to explore the extent to which spatial memory is differentially impaired following right temporal lobectomy was employed. The spatial and non-spatial memory of 19 left and 19 right temporal lobectomy (TL) patients was compared with that of 16 normal controls. The subjects studied an array of 16 toy objects and were subsequently tested for object recall, object recognition and memory for the location of the objects. By systematically varying the retention intervals for each group, it was possible to match all three groups on object recall at sub-ceiling levels. When memory for the position of the objects was assessed at equivalent delays, the right TL group revealed disrupted spatial memory, compared with both left TL and control groups (P < 0.05). MRI was used to quantify the extent of temporal lobe resection in the two groups and a significant correlation between hippocampal removal and both recall of spatial location and object name recall in the right TL group only was shown. These data support the notion of a selective (but not exclusive) spatial memory impairment associated with right temporal lobe damage that is related to the integrity of the hippocampal functioning.  (+info)

Unilateral neglect and disambiguation of the Necker cube. (4/4172)

Three groups of patients (right brain-damaged patients with or without left neglect, and left brain-damaged patients) and a group of healthy subjects, matched for age and educational level to the three groups of patients, were asked to report which of the two frontal surfaces of Necker cubes oriented in four different ways looked, at first sight, nearer to the viewer. The extent to which, and the way in which, disambiguation of the apparent perspective of Necker cubes occurred was found to vary across the four orientations and to be different in left-neglect patients compared with subjects of the other three groups. With normal subjects, the disambiguating factor is suggested to be a disposition to perceive the upper surface, which is nearly orthogonal to the frontal plane, as external to the cube. This would result from a navigation of the observer's spatial attention towards its target along a particular path that is altered in patients suffering from left neglect. It is suggested that comparison of the paths followed by the attentional vectors of normal subjects and left-neglect patients is potentially fruitful for a better understanding of the brain's normal mechanisms of spatial attention and of unresolved issues concerning the perception of the Necker cube.  (+info)

Spatial- and task-dependent neuronal responses during real and virtual translocation in the monkey hippocampal formation. (5/4172)

Neuropsychological data in humans demonstrated a pivotal role of the medial temporal lobe, including the hippocampal formation (HF) and the parahippocampal gyrus (PH), in allocentric (environment-centered) spatial learning and memory. In the present study, the functional significance of the monkey HF and PH neurons in allocentric spatial processing was analyzed during performance of the spatial tasks. In the tasks, the monkey either freely moved to one of four reward areas in the experimental field by driving a cab that the monkey rode (real translocation task) or freely moved a pointer to one of four reward areas on the monitor (virtual translocation task) by manipulating a joystick. Of 389 neurons recorded from the monkey HF and PH, 166 had place fields that displayed increased activity in a specific area in the experimental field and/or on the monitor (location-differential neurons). More HF and PH neurons responded in the real translocation task. These neurons had low mean spontaneous firing rates (0.96 spikes/sec), similar to those of rodent HF place cells. The remaining nonresponsive neurons had significantly higher mean firing rates (8. 39 spikes/sec), similar to interneurons or theta cells in the rodent HF. Furthermore, most location-differential neurons showed different responses in different tasks. These results suggest that the HF and PH are crucial in allocentric information processing and, moreover, that the HF can encode different reference frames that are context or task-dependent. This may be the neural basis of episodic memory.  (+info)

Crossmodal associative memory representations in rodent orbitofrontal cortex. (6/4172)

Firing patterns of neurons in the orbitofrontal cortex (OF) were analyzed in rats trained to perform a task that encouraged incidental associations between distinct odors and the places where their occurrence was detected. Many of the neurons fired differentially when the animals were at a particular location or sampled particular odors. Furthermore, a substantial fraction of the cells exhibited odor-specific firing patterns prior to odor presentation, when the animal arrived at a location associated with that odor. These findings suggest that neurons in the OF encode cross-modal associations between odors and locations within long-term memory.  (+info)

Functionally independent components of the late positive event-related potential during visual spatial attention. (7/4172)

Human event-related potentials (ERPs) were recorded from 10 subjects presented with visual target and nontarget stimuli at five screen locations and responding to targets presented at one of the locations. The late positive response complexes of 25-75 ERP average waveforms from the two task conditions were simultaneously analyzed with Independent Component Analysis, a new computational method for blindly separating linearly mixed signals. Three spatially fixed, temporally independent, behaviorally relevant, and physiologically plausible components were identified without reference to peaks in single-channel waveforms. A novel frontoparietal component (P3f) began at approximately 140 msec and peaked, in faster responders, at the onset of the motor command. The scalp distribution of P3f appeared consistent with brain regions activated during spatial orienting in functional imaging experiments. A longer-latency large component (P3b), positive over parietal cortex, was followed by a postmotor potential (Pmp) component that peaked 200 msec after the button press and reversed polarity near the central sulcus. A fourth component associated with a left frontocentral nontarget positivity (Pnt) was evoked primarily by target-like distractors presented in the attended location. When no distractors were presented, responses of five faster-responding subjects contained largest P3f and smallest Pmp components; when distractors were included, a Pmp component appeared only in responses of the five slower-responding subjects. Direct relationships between component amplitudes, latencies, and behavioral responses, plus similarities between component scalp distributions and regional activations reported in functional brain imaging experiments suggest that P3f, Pmp, and Pnt measure the time course and strength of functionally distinct brain processes.  (+info)

Space representation in unilateral spatial neglect. (8/4172)

Patients with unilateral brain lesions were given a task requiring exploration of space with the hand in order to assess the visual dependency of unilateral spatial neglect. The task was carried out both without visual control and under visual control. Performances were compared with that of normal subjects. Results were :(1) patients with right brain damage with no visual field defect demonstrated left-sided neglect only when the exploration was not controlled visually; (2) patients with left and right brain damage with visual field defect demonstrated contralateral neglect only when the exploration was under visual guidance. The performance of the patients with right brain damage without visual field defect in not clearly understood. The other results suggest that inner spatial representation remains intact in most cases of spatial neglect. The role of parietal lobe damage in the development of this visually induced phenomenon is hypothesised. The dominant position of vision among the senses is indicated.  (+info)

In the past few years, evidence has accumulated which suggests that many well-known spatial distortions might be related to systematic biases in two perceived angular variables - the perceived direction of gaze (e.g. gaze declination from horizontal) and the perceived optical slant of surfaces (Durgin and Li, 2011; Durgin and Li, in press; Durgin, Li and Hajnal, 2010; Li and Durgin, 2009, 2010; Li, Phillips and Durgin, 2011). It has been shown that in the range between 0° and 50°, both the perceived declination of gaze and the perceived optical slant of surfaces are expanded with a linear gain of about 1.5; perceived optical slant also increases as a function of viewing distance. An angular expansion hypothesis has been proposed which assumes that (1) there are perceptual biases in these two angular variables and (2) that the relationships between these and other perceived spatial variables otherwise still adhere to a Euclidean geometry. Specifically, it has been shown that such an angular ...
Get this from a library! Spatial cognition research : the human navigation process and its comparability in complex real and virtual environments. [Edna Platzer;]
To reinvestigate how place cells represent the environment, we made recordings as rats ran around inside a gray cylindrical apparatus with two distinct stimuli, a white card and a black card, pasted on the apparatus wall. There were four main findings. (a) In agreement with earlier work (Muller and Kubie 1987; Thompson and Best 1990), firing fields are stable for days when place cells are repeatedly recorded with the two cards in standard positions. (b) Equal rotations of the two cards on the cylinder wall caused firing fields to rotate by the same amount. Firing fields were otherwise unaltered by such rigid rotations. This nearly ideal control of firing fields by specific stimuli is also in agreement with previous work (OKeefe and Conway 1978; Muller and Kubie 1987; Sharp et al. 1990; Gothard et al. 1996; Cressant et al. 1997). (c) The only effect of removing one card and rotating the other was to cause uniform rotations of all firing fields. Thus, removal of one card did not cause firing ...

Verbal representations of space are related to the space they describe by a sign relation comprising three components. The first is the sign vehicle consisting of the sequence of words which describe the spatial environment. The second is the object of reference, the spatial environment as such, and the third is the mental representation of the spatial perception.Within this triad, space is never an unsemiotically given piece of reality. Space is always a semiotic phenomenon insofar as its structure depends on the process of human perception. Even as a referential object, space is not an independently given phenomenon of the real world itself but depends on the cognitive capacity and structure of the perceiving mind. ...
Chemists have developed a rich symbolic language to describe spatial relations of aperceptual particles of microscopic world (atoms, molecules) for interpreting, investigating and communicating chemical concepts and phenomena. The only perceivable features of microscopic world are those embedded in the symbolic chemical representations like molecular models, chemical structures, formulas, equations and symbols.. Research data tentatively reveal that understanding chemistry and performing in chemistry learning tasks using these representations are based upon the visuospatial (VS) ability of the learners, that is their capacity to perform spatial cognitive operations, such us recognition of graphic conventions and depth cues, manipulation of spatial information embedded in the representations, and mentally tracking of constraints based on concepts.. The aim of the proposed research, development and innovation project is: ...

Recent research shows that the spatial language parents use when talking to their children predicts their childs spatial language development (Pruden & Levine, in preparation). But parent spatial talk does not fully account for child spatial language. This study investigates whether the gestures parents produce along with spatial language have added value in predicting childrens acquisition of spatial language, over and above spatial language alone.. There are several reasons to expect that this may be the case. First, with respect to language acquisition in general, children are sensitive to the gestures of others in both conversational and pedagogical situations (Goldin-Meadow, 2003). At home, parents gestures predict childrens gestures and, in turn, their vocabulary size (Rowe & Goldin-Meadow, 2009). In instructional situations, children learn more from spoken instruction if it is accompanied by gesture than if it is not (Church, Ayman-Nolley, & Mahootian, 2004; Valenzeno, Alibali, & ...

A New Spatial Transformation Scheme for Preventing Location Data Disclosure in Cloud Computing: 10.4018/978-1-4666-9845-1.ch084: Because much interest in spatial database for cloud computing has been attracted, studies on preserving location data privacy have been actively done.
Background The capacity of visual working memory (WM) is substantially limited and only a fraction of what we see is maintained as a temporary trace. The process of binding visual features has been proposed as an adaptive means of minimising information demands on WM. However the neural mechanisms underlying this process, and its modulation by task and load effects, are not well understood. Objective To investigate the neural correlates of feature binding and its modulation by WM load during the sequential phases of encoding, maintenance and retrieval. Methods and Findings 18 young healthy participants performed a visuospatial WM task with independent factors of load and feature conjunction (object identity and position) in an event-related functional MRI study. During stimulus encoding, load-invariant conjunction-related activity was observed in left prefrontal cortex and left hippocampus. During maintenance, greater activity for task demands of feature conjunction versus single features, and for

With event-related functional magnetic resonance imaging (fMRI), we investigated changes of connectivity during shifts of spatial attention from an attended location to a previously unattended target location. Using a 3-T scanner, fMRI data were acquired from three healthy volunteers. According to a central visual cue, participants directed endogenous spatial attention to the left or the right visual hemifield for blocks of 56 s. Peripheral visual targets were presented unpredictably in either the attended hemifield (valid trials, 80%) or in the unattended hemifield (invalid trials, 20%) and participants performed a two-alternative ...
Because of our limited processing capacity, different elements of the visual scene compete for the allocation of processing resources. One of the most striking deficits in visual selection is simultanagnosia, a rare neuropsychological condition characterized by impaired spatial awareness of more than one object at time. To decompose the neuroanatomical substrates of the syndrome and to gain insights into the structural and functional organization of visuospatial attention, we performed a systematic evaluation of lesion patterns in a group of simultanagnosic patients compared with patients with either (i) unilateral visuospatial deficits (neglect and/or extinction) or (ii) bilateral posterior lesions without visuospatial deficits, using overlap/subtraction analyses, estimation of lesion volume, and a lesion laterality index. We next used voxel-based morphometry to assess the link between different visuospatial deficits and gray matter and white matter (WM) damage. Lesion overlap/subtraction analyses,
TY - JOUR. T1 - Dynamically detuned oscillations account for the coupled rate and temporal code of place cell firing. AU - Lengyel, Máté. AU - Szatmáry, Zoltán. AU - Érdi, Péter. PY - 2003/9/22. Y1 - 2003/9/22. N2 - Firing of place cells in the exploring rat conveys doubly coded spatial information: both the rate of spikes and their timing relative to the phase of the ongoing field theta oscillation are correlated with the location of the animal. Specifically, the firing rate of a place cell waxes and wanes, while the timing of spikes precesses monotonically as the animal traverses the portion of the environment preferred by the cell. We propose a mechanism for the generation of this firing pattern that can be applied for place cells in all three hippocampal subfields and that encodes spatial information in the output of the cell without relying on topographical connections or topographical input. A single pyramidal cell was modeled so that the cell received rhythmic inhibition in phase ...

Imagine struggling to see, listen, or make movements in half of your environment. This is typical for individuals who suffer from unilateral spatial neglect, a common post-stroke deficit of attention to objects or events on the side opposite of the brain injury. The condition has a major impact on the everyday lives of stroke survivors and has shown to be a strong predictor of disability.
ndividuals with Williams syndrome typically show relatively poor visuospatial abilities in comparison to stronger verbal skills. However, individuals level of performance is not consistent across all visuospatial tasks. The studies assessing visuospatial functioning in Williams syndrome are critically reviewed, to provide a clear pattern of the relative difficulty of these tasks. This prompts a possible explanation of the variability in performance seen, which focuses on the processing demands of some of these tasks. Individuals with Williams syndrome show an atypical processing style on tests of construction, which does not affect tests of perception.. ...
Functional MRI was used to examine cerebral activations in 12 subjects while they performed a spatial attention task. This study applied more stringent behavioural and cognitive controls than previously used for similar experiments: (i) subjects were included only if they showed evidence of attentional shifts while performing the task in the magnet; (ii) the experimental task and baseline condition were designed to eliminate the contributions of motor output, visual fixation, inhibition of eye movements, working memory and the conditional (no-go) component of responding. Activations were seen in all three hypothesized cortical epicentres forming a network for spatial attention: the lateral premotor cortex (frontal eye fields), the posterior parietal cortex and the cingulate cortex. Subcortical activations were seen in the basal ganglia and the thalamus. Although the task required attention to be equally shifted to the left and to the right, eight of 10 subjects showed a greater area of activation in the

We did not analyze this subset further. Furthermore, among neurons with significant shape selectivity, those preferring either ...
The thesis aspires to challenge CP by means of this formal analysis. Whether it belongs to a simple technique or a sophisticated visual scheme of ancient Chinese artists; the representational space of geometry; the making of visual perception by means of technical implements; and the bodily experience in actual space, are all shown to be indispensible parts of the present research. A concluding case study of the Chinese landscape garden gives a further demonstration that the pictorial ideas and visual techniques that once contributed to the iconological and psychological understanding of Chinese painting have also delivered an idealised form of spatial perception within the garden - where the sense of depth is firstly eliminated, and then artistically reconstituted. In this way, the nature of cavalier perspective will therefore have been explored on two levels - in the form of both spatial representation and bodily perception in actual space.. ...
Neurophysiological research has led to detailed mechanistic theories about how spatial locations and headings are represented in the brain and used in memory and navigation. INTRODUCTION 0369.001 The term`spatial cognition covers processes controlling behaviour that must be directed at particular locations, or responses that depend on the location or spatial arrangement of stimuli. There are many circumstances in which such processes are required for adaptive behaviour, and they are exhibited in creatures as diverse as bees, birds, rats and primates. At the most basic level, an organism must be able to flee from a dangerous location to a safer place. It may also need to return to a location where food is abundant or has been stored; to act upon a stimulus at one location, while temporarily ignoring other stimuli; or to navigate from one place to another by an efficient route, avoiding obstacles. All of these behaviours seem to demand some sort of spatial representation; a neural code that distinguishes
We develop a two-stage spatial point process model that introduces new characterizations of activation patterns in multisubject functional Magnetic Resonance Imaging (fMRI) studies. Conventionally multisubject fMRI methods rely on combining information across subjects one voxel at a time in order to identify locations of peak activation in the brain. The two-stage model that we develop here addresses shortcomings of standard methods by explicitly modeling the spatial structure of functional signals and recognizing that corresponding cross-subject functional signals can be spatially misaligned. In our first stage analysis, we introduce a marked spatial point process model that captures the spatial features of the functional response and identifies a configuration of activation units for each subject. The locations of these activation units are used as input for the second stage model. The point process model of the second stage analysis is developed to characterize multisubject activation patterns by
We argue that current theories of multisensory representations are inconsistent with the existence of a large proportion of multimodal neurons with gain fields and partially shifting receptive fields. Moreover, these theories do not fully resolve the recoding and statistical issues involved in multisensory integration. An alternative theory, which we have recently developed and review here, has important implications for the idea of frame of reference in neural spatial representations. This theory is based on a neural architecture that combines basis functions and attractor dynamics. Basis function units are used to solve the recoding problem, whereas attractor dynamics are used for optimal statistical inferences. This architecture accounts for gain fields and partially shifting receptive fields, which emerge naturally as a result of the network connectivity and dynamics.
Spatial perception is biased by action. Hills appear steeper and distances appear farther to individuals who would have to exert more effort to transverse the space. Objects appear closer, smaller, and faster when they are easier to obtain. Athletes who are playing better than others see their targets as bigger. These phenomena are collectively known as action-specific effects on perception. In this target article, we review evidence for action-specific effects, including evidence that they reflect genuine changes in perception, and speculate on possible applications of actions influence on vision.. ...
This study investigated whether eye proprioception contributes to visual localization. We tested whether a patient with a presumed deficit in eye proprioception after a focal lesion in the left postcentral gyrus made more errors in locating a visual target relative to the head midline compared with an aged-matched control group. Although the patient was as accurate and precise as the control group under the normal, baseline condition, she exhibited a significant error when the position of one eye was perturbed peripherally. In this condition, we found a shift to the left in perceived straight ahead when the task was executed with the left, contralesional eye. This corresponds to a shift toward the nose in perceived eye position, in the direction of the applied force. The direction of this shift is identical with that produced by a push after 1 Hz rTMS in healthy subjects, a procedure that decreased the excitability of the eye proprioceptive area (Balslev and Miall, 2008). The illusory eye ...

I should back up a little. I didnt actually think Id find the house where my MC lived. It just happened. See, when I write, I do these little visual reference boards where I find pics of everything in my story - towns, houses, apartments, cars, restaurants, parks, offices - whatever pertains to the story (thank you Google images!). When I made the board for my current novel, I got on Realtor.com and found houses for sale in Cle Elum, and found a house that would be perfect...it was big and had a large upstairs/attic with windows that could easily be an upstairs apartment. So, while Im driving around the little residential streets just to get a feel of what the houses near the downtown area look like, I turn a corner and holy-crap-on-a-crap-cracker, theres the house! Of course, I started flipping out (luckily Ive been flipping out about bizarre things since before I could walk, so this didnt faze my mother). It was the strangest feeling...this house that Ive been staring at for months ...
