“…(b) Neuroimaging study Consistent with predictions, relative to the mean cortical thickness of the control group, GW's cortex was: (i) thinner in regions associated with social cognition and other domains impaired in ASD ), but (ii) thicker in a bilateral segment of the superior parietal lobe, which has been connected with drawing and other visuospatial functions (Makuuchi et al 2003;Simon et al 2004) as well as calculation abilities . Without longitudinal imaging we cannot establish whether these anatomical differences played a part in the initial selection of GW's talent domains, or are the result of talent development and practice.…”

“…Makuuchi et al (2003) consistently observed bilateral (particularly superior) parietal lobe activations across participants when they were asked to 'draw in the air' a contour of an object depicted on a screen. Furthermore, visual mental imagery, a skill potentially relevant to talent in the visual arts, is also associated with activation in the superior parietal lobe (e.g.…”

Neuropsychological functioning and brain morphometry in a savant (case GW) with an autism spectrum disorder (ASD) and both calendar calculation and artistic skills are quantified and compared with small groups of neurotypical controls. Good memory, mental calculation and visuospatial processing, as well as (implicit) knowledge of calendar structure and 'weak' central coherence characterized the cognitive profile of case GW. Possibly reflecting his savant skills, the superior parietal region of GW's cortex was the only area thicker (while areas such as the superior and medial prefrontal, middle temporal and motor cortices were thinner) than that of a neurotypical control group. Taken from the perspective of learning/practice-based models, skills in domains (e.g. calendars, art, music) that capitalize upon strengths often associated with ASD, such as detailfocused processing, are probably further enhanced through over-learning and massive exposure, and reflected in atypical brain structure.

“…Investigations conducted in patients with focal brain lesions and with different forms of dementia have shown that many of these disorders can be traced back to visual-spatial [1][2][3][4][5] or planning disturbances [6][7][8][9][10]. These disorders are the main determinants of constructional apraxia (CA) and are subsumed by lesions affecting the parietal [11][12][13][14] and frontal regions of the brain [15]. They are usually observed in copying tasks, whereas other forms of drawing disorders, mainly due to disruption of (or impaired access to) the pictorial representations of objects, can be observed on tasks of drawing from memory [16][17][18][19].…”

Abstract. Drawing is a multicomponential process that can be impaired by many kinds of brain lesions. Drawing disorders are very common in Alzheimer's disease and other forms of dementia, and can provide clinical information for the distinction of the different dementing diseases. In our review we started from an overview of the neural and cognitive bases of drawing, and from a recollection of the drawing tasks more frequently used for assessing individuals with dementia. Then, we analyzed drawing disorders in dementia, paying special attention to those observed in Alzheimer's disease, from the prodromal stages of the amnesic mild cognitive impairment to the stages of full-blown dementia, both in the sporadic forms with late onset in the entorhino-hippocampal structures and in those with early onset in the posterior neocortical structures. We reviewed the drawing features that could differentiate Alzheimer's disease from vascular dementia and from the most frequent forms of degenerative dementia, namely frontotemporal dementia and Lewy body disease. Finally, we examined some peculiar aspects of drawing disorders in dementia, such as perseverations, rotations, and closing-in. We argue that a careful analysis of drawing errors helps to differentiate the different forms of dementia more than overall accuracy in drawing.

“…In the present study, hemispheric information processing was evaluated, using functionally connectivity measures, during motor tasks that involved drawing actions. Previously, it has been established that drawing behaviour engages distributed brain regions [19]; an observation that is supported from patient work that has shown that visuo-spatial tasks are impaired following left as well as right hemisphere lesions [12,36]. However, the intricacy of the drawing activity depends on a number of factors such as feedback availability (normal vs. degraded) and task complexity (characterized by the topology of the figure and spatial characteristics of the components).…”

Please see the repository url above for details on accessing the published version and note that access may require a subscription.For more information, please contact eprints@nottingham.ac.uk Interactions between brain regions are necessary for compound activities to take place. Accordingly, evaluating hemispheric information processing during skilled behaviour provides valuable knowledge about brain regulation. To this end, the present study assessed the neural changes in response to task complexity and visuomotor discrepancy during motor (drawing) actions. EEG phase synchronization, expressing interregional communication, showed that visuomotor discordance perturbed information processing across both hemispheres, whereas task complexity induced pronounced adjustments in the left (dominant) hemisphere. However, the effects of task complexity and sensorimotor conflict interacted, and suggested that the main process of spatiotemporal integration was localized within the left hemisphere. Furthermore, a significant association between left hemisphere couplings and performance accuracy proposed that connectivity strength and behavioural output are linked with one another. These results suggest that functional connectivity patterns provide higher-order associations for information coding during skilled actions.
