Hemispatial neglect following right-hemisphere stroke is a common and disabling disorder, for which there is currently no effective pharmacological treatment. Dopamine agonists have been shown to play a role in selective attention and working memory, two core cognitive components of neglect. Here, we investigated whether the dopamine agonist rotigotine would have a beneficial effect on hemispatial neglect in stroke patients. A double-blind, randomized, placebo-controlled ABA design was used, in which each patient was assessed for 20 testing sessions, in three phases: pretreatment (Phase A1), on transdermal rotigotine for 7-11 days (Phase B) and post-treatment (Phase A2), with the exact duration of each phase randomized within limits. Outcome measures included performance on cancellation (visual search), line bisection, visual working memory, selective attention and sustained attention tasks, as well as measures of motor control. Sixteen right-hemisphere stroke patients were recruited, all of whom
The role of the inferior parietal lobule (IPL) and superior temporal gyrus (STG) or subcortical pathways as possible anatomical correlates of spatial neglect is currently intensely discussed. Some of the conflicting results might have arisen because patients were examined in the acute stage of disease. We examined the anatomical basis of spatial neglect in a sample of patients examined in the post-acute stage following right-hemispheric vascular brain damage. Lesions of 28 patients with chronic spatial neglect were contrasted to lesions of 22 control patients without neglect using lesion subtraction techniques and voxel-wise comparisons. The comparisons identified the temporo-parietal junction (TPJ) with underlying white matter, the supramarginal gyrus, the posterior STG, and the insula as brain regions damaged significantly more often in neglect compared to non-neglect patients. In a subgroup of neglect patients showing particularly large cancellation bias together with small errors on line bisection
Persistent leftward visual neglect following right hemisphere stroke has a poor prognosis for functional independence.1 Devising treatments for this condition requires a better understanding of underlying mechanisms.2 The report by Schnider et al3 strikingly demonstrates a key factor that might be a target for future therapeutic strategies and also reveals how neglect is very different from fixed visual deficits such as hemianopia.. In left homonymous hemianopia, the left visual field is missing for the patient, with a sharp cut-off at the vertical meridian (figure 1B). Neglect is very different. A growing body of evidence demonstrates that the condition is better conceptualised as a gradient of visual unawareness, with no sharp vertical division in awareness (figure 1C). Indeed, whether an … ...
I am the co-founder of synesthesia.com and an Alpine plant biologist. At the age of 15 years, I found out that I am a synesthete. First I thought I am special and alone. Then I discovered that some of my friends and family members also have synesthesia. I realized, that many people resonate with synesthesia, but most are not aware of it. I spent over a decade finding methods to support people and discovering and experiencing synesthesia. I am not a meditation guru, but an expert in synesthesia. I realized that Meditation combined with synesthetic explorations is a great opportunity to experience synesthesia. And this is why I initiated synesthesia.com. More about the team ...
Objective: Vestibular signals are involved in higher cortical functions like spatial orientation and its disorders. Vestibular dysfunction contributes, for example, to spatial neglect which can be transiently improved by caloric stimulation. The exact roles and mechanisms of the vestibular and visual systems for the recovery of neglect are not yet known. Methods: Resting-state functional connectivity (fc) magnetic resonance imaging was recorded in a patient with hemispatial neglect during the acute phase and after recovery 6 months later following a right middle cerebral artery infarction before and after caloric vestibular stimulation. Seeds in the vestibular [parietal operculum (OP2)], the parietal [posterior parietal cortex (PPC);7A, hIP3], and the visual cortex (VC) were used for the analysis. Results: During the acute stage after caloric stimulation the fc of the right OP2 to the left OP2, the anterior cingulum, and the para/hippocampus was increased bilaterally (i.e., the vestibular ...
Synaesthesia is a hereditary, neurological condition in which common stimuli trigger unexpected secondary sensations. For example, reading letters may result in the visualisation of colour, a variant known as grapheme-colour synaesthesia. While synaesthesia is thought to confer a range of benefits such as improved memory, empathy, visual search and creativity to the synaesthete, there is a small, yet growing, body of evidence that suggests synaesthesia may also be associated with more clinical conditions. This thesis investigates potential associations between synaesthesia and a range of clinical conditions, identifying a set of cormorbidities, and exploring the possible genetic roots of these associations. First, I identified an increased prevalence of multiple sclerosis (MS) and its clinical precursor, radiologically isolated syndrome (RIS) in synaesthetes self-referring for participation in scientific studies. Furthermore, I identified an increased occurrence of anxiety disorder in randomly ...
Rightward prism adaptation ameliorates neglect symptoms while leftward prism adaptation (LPA) induces neglect-like biases in healthy individuals. Similarly, inhibitory repetitive transcranial magnetic stimulation (rTMS) on the right posterior parietal cortex (PPC) induces neglect-like behavior, whereas on the left PPC it ameliorates neglect symptoms and normalizes hyperexcitability of left hemisphere parietal-motor (PPC-M1) connectivity. Based on this analogy we hypothesized that LPA increases PPC-M1 excitability in the left hemisphere and decreases it in the right one. In an attempt to shed some light on the mechanisms underlying LPA’s effects on cognition, we investigated this hypothesis in healthy individuals measuring PPC-M1 excitability with dual-site paired-pulse TMS (ppTMS). We found a left hemisphere increase and a right hemisphere decrease in the amplitude of motor evoked potentials elicited by paired as well as single pulses on M1. While this could indicate that LPA biases
Visual neglect of left space following right parietal damage in humans involves a lateral bias in attention, apparent in many search tasks. We hypothesized that parietal neglect may also involve a failure to remember which locations have already been examined during visual search: an impairment in retaining searched locations across saccades. Using a new paradigm, we monitored gaze during search, while simultaneously probing whether observers judged they had found a new target, or judged instead that they were re-fixating a previously examined target. A patient with left neglect following focal right parietal infarction repeatedly re-fixated right locations. Critically, he often failed to remember that these locations had already been searched, treating old targets as new discoveries at an abnormal rate. In comparison, healthy age-matched control subjects rarely re-fixated targets, and mistook old targets as new targets even more rarely. The frequency of such mistakes in the parietal patient, for
methods used to decompose neuroanatomy of visuospatial disorders. The first study contrasted the neural substrates of different neglect symptoms, specifically the contributions of common and dissociable grey and white matter changes linked to allocentric and egocentric neglect. Two following studies decomposed the neuroanatomy of frequently co-occurring spatial attention syndromes by examining (1) the lesion patterns associated with visual and tactile extinction vs. those related to visual field defects and neglect, and (2) the lesion pattern linked to simultanagnosia, extracting out lesions associated with unilateral visuospatial deficits. These studies demonstrated that the different patterns of grey matter lesions in individual patients, and the laterality of white matter disconnections, determine the degree to which visual processing and spatial attention are disrupted and thus the nature of the observed cognitive symptoms. The final study examined the neuroanatomy of subacute relative to ...
Visual extinction after right parietal damage involves a loss of awareness for stimuli in the contralesional field when presented concurrently with ipsilesional stimuli, although contralesional stimuli are still perceived if presented alone. However, extinguished stimuli can still receive some residual on-line processing, without awareness. Here we examined whether such residual processing of extinguished stimuli can produce implicit and/or explicit memory traces lasting many minutes. We tested four patients with right parietal damage and left extinction on two sessions, each including distinct study and subsequent test phases. At study, pictures of objects were shown briefly in the right, left, or both fields. Patients were asked to name them without memory instructions (Session 1) or to make an indoor/outdoor categorization and memorize them (Session 2). They extinguished most left stimuli on bilateral presentation. During the test (up to 48 min later), fragmented pictures of the previously exposed

Synesthesia, as it is defined now, is a sensation that normally occurs in one sense modality occuring when another modality is stimulated. But what of the lit quality of the photisms synesthetes see? And what of the colors they often associate with things like numbers, letters and music? And then there are their prodigious memories - aided by this color, which acts like a mnemonic… And what of the landscapes that they see, alphabets sometimes climbing upwards or ...
Prism adaptation is impaired by lesions in the basal ganglia in non-human primates, suggesting that this area is involved in this form of visuomotor learning. We investigated the ability of patients with Parkinsons disease to prism adapt. Patients and controls wore prisms which deflected vision laterally by 11 degrees. After baseline testing with a localisation task that permitted no feedback about performance accuracy, prism adaptation was tested at 4 minute intervals over a 28 minute trial. All subjects erred initially, reaching too far to the left of the target, but a separate pointing task encouraged adaptation and reaching error decreased at a similar rate in Parkinsonians and controls. Immediately after the prisms were removed, all subjects reached to the right of the target. This negative after effect was present in controls but not patients when assessed 4 minutes later, suggesting that the patients could not maintain the new sensorimotor relationship imposed by the prisms after their removal.
Reaction time studies have shown that number-form synesthetes are faster to say which of two numbers is larger when the numbers are arranged in a manner consistent with their number-form, suggesting that number forms are automatically evoked (Sagiv et al. 2006; Piazza et al.). This can be thought of as a spatial Stroop task, in which space is not relevant to the task, but which can hinder performance despite its irrelevance. The fact that synesthetes cannot ignore the spatial arrangement of the numbers on the screen demonstrates that numbers are automatically evoking spatial cues. The reaction times for valid cues are smaller than invalid cues (words and arrows), but in synesthetes the response time differences for months are larger than those of non-synesthetes (Teuscher et al. 2010). ...

Secondary goal: to establish a functional correlate of a radiologically defined ischemic penumbra. Methods: Forty subjects underwent DWI, MRPI, and standardized tests for lexical deficits or hemispatial neglect within 24 hours of stroke onset or progression. Ten patients had repeat DWI, MRPI, and cognitive testing after 3 days (in some cases after reperfusion therapy). Pearson correlations between error rate on cognitive testing and volume of abnormality on DWI versus MRPI were determined at each time period, and regions of hypoperfusion ...

OBJECTIVES: To investigate the characteristics and neuroanatomical correlates of visual neglect after right-sided posterior cerebral artery (PCA) infarction. METHODS: 15 patients with acute PCA strokes were screened for the presence of neglect on a comprehensive battery of cognitive tests. Extra tests of visual perception were also carried out on six patients. To establish which areas were critically associated with neglect, the lesions of patients with and without neglect were compared. RESULTS: Neglect of varying severity was documented in 8 patients. In addition, higher-order visual perception was impaired in 5 of the 6 patients. Neglect was critically associated with damage to an area of white matter in the occipital lobe corresponding to a white matter tract connecting the parahippocampal gyrus with the angular gyrus of the parietal lobe. Lesions of the thalamus or splenium of the corpus callosum did not appear necessary or sufficient to cause neglect, but may mediate its severity in these patients
Time Discrimination Task Time discrimination task, modified from Smith et al. (2002) presents the green circle on the left first, followed by the red circle on the right. The subject is asked to press the key to indicate the circle with longer duration. The standard stimuli and comparison last for 1000ms, and 1350ms, respectively. The two circles are randomly presented. If the answer is correct, the comparison duration decreases in 15ms; if the answer is wrong, the comparison duration increases in 15ms. The task continued either until the subject had made six reversals, or until 20 trials, whichever occurs first.. Time Reproduction Task The time reproduction task is modified from Barkley et al. (1997). First, the green circle is present on the central for seconds with five durations: 2, 5, 10, 12, and 17seconds. Subject is asked to press key to create the same temporal duration as green circle. Two trials are given at each of these five durations with random presentation.. The raw time ...

For the first time, we report a spatial bias in visual short-term memory (VSTM) after left medial and inferior occipito-temporal damage. Our patient D.M. showed a spatial bias in report from VSTM, being more accurate at reporting stimuli presented in her left than her right visual field (Experiment 1). This spatial bias could not be attributed to a visual field deficit (Experiment 2) and was based on the relative rather than the absolute locations of the stimuli (Experiment 3). It was reduced when the transfer of items to VSTM was facilitated-for example, by grouping stimuli (Experiment 4) or by reducing the number of items to be remembered (Experiment 5). The spatial bias was attenuated when items moved from right to centre or left to centre, and D.M. was cued to report the item that would have been on the right or left, had the movement continued (Experiment 6). We conclude that posterior ventral damage can impair both the consolidation of new information in VSTM and the explicit report of
PASADENA, Calif.-- Individuals with synesthesia perceive the world in a different way from the rest of us. Because their senses are cross-activated, some synesthetes perceive numbers or letters as having colors or days of the week as possessing personalities, even as they function normally in the world. Now, researchers at the California Institute of Technology have discovered a type of synesthesia in which individuals hear sounds, such as tapping, beeping, or whirring, when they see things move or flash. Surprisingly, the scientists say, auditory synesthesia may not be unusual--and may simply represent an enhanced form of how the brain normally processes visual information.. Psychologists previously reported visual, tactile, and taste synesthesias, but auditory synesthesia had never been identified. Caltech lecturer in computation and neural systems Melissa Saenz discovered the phenomenon quite by accident.. While I was running an experiment at the Caltech Brain Imaging Center, a group of ...
In this last section, I will briefly review what is known about the genetics of synaesthesia and the implications for understanding individual differences in perceptual experience. A discussion on synaesthesia art and creativity will follow (Is there a link? Synaesthesia as a tool for artistic experimentation. Synaesthetic experience as a source for art - some challenges to the way we think about art). The workshop will conclude with an open discussion. Some of the open questions in synaesthesia research will likely be addressed: Are we all synaesthetes? Should our definition of synaesthesia be more inclusive? What is so special about colour (that it is rated as the most common synaesthetic experience)? FURTHER READING. Lynn C. Robertson & Noam Sagiv (Eds).

Color-grapheme synesthetes automatically perceive achromatic numbers as colored (e.g., 7 is turquoise). Up until recently, synesthesia was believed to be unidirectional. For instance, the number 7 gives rise to the percept of turquoise but the perception of turquoise does not trigger the number 7. However, some recent studies argue for bidirectional connections Cohen Kadosh et al., 2005; Johnson et al., 2007; Knoch et al., 2005). In this study, a multiplication verification task (e.g., 7 x 2 = 14, true/false?) was used to test bidirectionality. In agreement with previous studies we observed that the presentation of colors evokes numerical magnitudes. The current findings add two important notions to previous studies: (a) The influence of color on the processing of numerical information can be extended to multiplication verification tasks and (b) The perception of color can both facilitate and interfere with the processing of digit-related information.
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 ...
Child neglect, often overlooked, is the most common form of child maltreatment. Most perpetrators of child abuse and neglect are the parents themselves. A total of 79.4% of the perpetrators of abused and neglected children are the parents of the victims, and of those 79.4% parents, 61% exclusively neglect their children. The physical, emotional, and cognitive developmental impacts from child neglect in early childhood can be detrimental as the effects from the neglect can carry on into adulthood. Research has shown that by the time a child reaches the age of six, if they have experienced adverse exposures, such as neglect, their chances of having overall poor physical health increases by two-fold. Infants can develop poor physical health if neglect starts even before the child is born. A child deprived of basic necessities, such as proper pre-natal care, is at risk of being born prematurely or having complications during birth. A common outcome of medical neglect is failure to thrive in infants ...

Following lesions to (usually) the right parietal lobe, patients may fail to report stimuli on their contralesional side if a stimulus is also presented ipsilesionally. The problem can be ameliorated if the stimuli form part of a common action (e.g., a bottle pouring into a glass), when the contralesional item may be brought to awareness. We examined whether this improved awareness depended on implied motion from one object to another. This was tested using pairs of stimuli in which one had implied motion towards or away from the other stimulus. The results showed that patients were more aware of the presence of two objects on trials when one object had implied motion towards the other, compared with when motion was directed away from the second object. This held when the implied motion was in the contralesional as well as when it was in the ipsilesional field. In a single case, this effect held even when the direction of motion could not be explicitly discriminated. The data suggest that motion was
As $m_u - m_b ≠ (U-B)_0$, I gathered that the distance modulus cant be used directly, since extinction is present. From the bolometric correction (BC), we can determine that the absolute visual magnitude $M_v = 8.33$. After that, Im unsure of what to do; normally I think in these questions you can obtain the visual extinction $A_v = 3.0E_{B-V}$, where $E_{B-V}$ is the color excess, calculated by $E_{B-V} = (m_b - m_v) - (B-V)_0$. Then, the visual extinction can be added to the distance modulus equation to account for extinction in the visual band, and then we can easily obtain distance.. But, while we know $m_b$, $m_v$, and $M_v$, we dont really have a way of obtaining $(B-V)_0$ to my knowledge, unless theres some way we can relate it to $(U-B)_0$. Any help would be much appreciated!. ...
Although it has been established that human beings process concrete and abstract words differently, it is still a matter of debate what factors contribute to this difference. Since concrete concepts are closely tied to sensory perception, perceptual experience seems to play an important role in their processing. The present study investigated the processing of nouns during an auditory lexical decision task. Participants came from three populations differing in their visual-perceptual experience: congenitally blind persons, word-color synesthetes, and sighted non-synesthetes. Specifically, three features with potential relevance to concreteness were manipulated: sensory perception, emotionality, and Husserlian lifeworld, a concept related to the inner versus the outer world of the self. In addition to a classical concreteness effect, our results revealed a significant effect of lifeworld: words that are closely linked to the internal states of humans were processed faster than words referring to ...
Methods- Individual patient-level data were combined in this meta-analysis of all patients included in randomized trials comparing endovascular thrombectomy predominantly done with stent retrievers with standard care in anterior circulation ischemic patients with stroke (HERMES [Highly Effective Reperfusion Using Multiple Endovascular Devices] Collaboration). We stratified the 90-day functional outcome assessed by ordinal analysis of the modified Rankin Scale according to the stroke side of patients treated with endovascular therapy versus standard care, adjusted for important prognostic variables. Results- The meta-analysis included 1737 patients (871 right hemispheric strokes and 866 left hemispheric) from 7 trials. Baseline median National Institutes of Health Stroke Scale scores were significantly higher in left (20) versus right (16) hemispheric strokes (P,0.001). Other clinical and radiological baseline characteristics were similar. The beneficial response to endovascular therapy assessed ...
As has been appreciated from previous studies, ASP lesions of OFC (Butter, 1969; Iversen and Mishkin, 1970; Meunier et al., 1997; Izquierdo et al., 2004), as well as lesions of rhinal cortex, excitotoxic lesions of the hippocampus, and unilateral lesions of OFC and the amygdala within one hemisphere (Murray et al., 1998; Izquierdo et al., 2004) all produce significant impairments in reversal learning. Prior studies testing for visual perceptual deficits in monkeys with rhinal cortex lesions (Gaffan and Murray, 1992; Meunier et al., 1993) suggest that visual perceptual abilities are not the primary cause of the impairments in reversal learning for monkeys in this lesion cluster. Here, we also show these deficits are not due to an inability of the animals to develop a learning set and are instead attributable to a need for greater evidence in favor of a reversal before the animals switched their behavior.. In contrast to the cluster with deficits relative to controls, we also identified a cluster ...
The research supported by this grant focused on the structure of high-level visual processing. Five types of research were conducted 1 We performed case studies of individual brain-damaged patients. We found evidence that curved edges are processed separately from straight edges and that location information sometimes can be used to encode some characteristics of shape. 2 We tested groups of brain-damaged patients with specific types of lesions. We found evidence that metric information may be used to encode spatial categories such as abovebelow, and that imagery may involve some structures that are intact even when the visual field is disrupted. 3 We developed a computerized visualspatial test battery, and administered it to a group of 19 brain-damaged patients. The results indicate that most of the visualspatial abilities we examined can be impaired independently, suggesting that at least some distinct subsystems carry out each ability. 4 We implemented computer models and found support for the

In 1929, the German-American scientist Wolfgang Kohler observed what is now known as the Bouba-Kiki effect [1]. In 2001, Vilyanur S. Ramachandran replicated Kohlers experiment with college students in the United States and India, and found a large consensus between participants prompted to provide auditory names to visual objects [2]. The findings of Ramachandran and Kohler demonstrate that sensory information appears to carry a predictable and consistent scaffolding of associations and relationships to other modalities of stimuli. The participants visual perceptions of the shapes printed on the page were used to make judgments of the appropriate auditory sounds that ought to be associated with those shapes. VS Ramachandran and his colleague Edward Hubbard suggest that the evolution of language may not be entirely arbitrary-instead, the naming of objects in space may reflect a natural association of auditory stimuli with the visual, tactile, olfactory, and overall perception of the objects ...

A study carried out on behalf of the NSPCC found that 1 in 10 children in the UK have experienced neglect and that 1 in 5 children have experienced severe maltreatment.*. Shocking isnt it?. We read horrendous statistics like this, but often we think that these things happen a long way away, in urban, over crowded, inner city locations and not in my town, village or street.. Unfortunately the statistics tell a different story and children are suffering closer than you think..

This study investigated inhibition of return in persons with and without Down syndrome (DS) when visual or verbal cues were used to specify a target in a crossmodal paradigm. Individuals with DS and without DS performed manual aiming movements to a target located in right or left hemispace. The target was specified by an endogenous visual or verbal stimulus. Both groups were significantly slower when responding to the same target as the previous trial when the target was cued in a different modality. Although participants with DS initiated and executed their movements more slowly, they demonstrated a similar pattern of inhibition as people without DS, suggesting that inhibitory processes are functioning normally in persons with DS ...

Another of your examples, neuropsychological case studies, is particularly difficult. Are you not supposed to test the rare individual with hemi-prosopagnosia or a unique form of synesthesia? Many aging and developmental studies could be problematic too. What if your elderly group is no better than chance in a memory test that undergrads could do at 80% accuracy? Maybe your small pilot sample of elderly were very high performers and not representative? Obviously, being locked into publishing such a study would set you back the time it would take to make the task easier and re-run the experiment. You could even say in the new paper that you ran the experiment with 500 items in the study list and the elderly were no better than chance. Whos to say that a reviewer would have caught that error in advance ...

Hi, we are using py.test in SymPy and unfortunately, we have some bugs in SymPy, that occurs when certain tests are run and dont occur when the tests are run in different order. Its very time consuming to determine which tests cause the problem (I did that several times by hand). It occured to me that it should be possible to enhance py.test by this facility to do it automatically. Example: 1) This passes: $ py.test sympy/series/tests/test_series.py -k issue409 This doesnt 2) $ py.test One problem is, that 2) runs for several minutes, another problem is that I need to specify all tests on the command line and then deleting some of them it see if it still fails, until I narrow the issue down, usually quite nicely. Then I need to play with the -k parameter to try different test cases in the file, until I determine the minimal set of tests that, when executed in order, produce the error. This can by done automatically - the py.test will be given a set of files (or just tests) that pass and ...
