Optic ataxia is a neuropsychological disorder that affects the ability to interact with objects presented in the visual modality following either unilateral or bilateral lesions of the posterior parietal cortex (PPC). Patients with optic ataxia fail... Read More about Optic ataxia as a model to investigate the role of the posterior parietal cortex in visually guided action: Evidence from studies of patient M.H.

The Magic Grasp: Motor Expertise in Deception (2011)
Journal Article
Cavina-Pratesi, C., Kuhn, G., Ietswaart, M., & Milner, A. (2011). The Magic Grasp: Motor Expertise in Deception. PLoS ONE, 6(2), Article e16568. https://doi.org/10.1371/journal.pone.0016568

Background Most of us are poor at faking actions. Kinematic studies have shown that when pretending to pick up imagined objects (pantomimed actions), we move and shape our hands quite differently from when grasping real ones. These differences betwee... Read More about The Magic Grasp: Motor Expertise in Deception.

Functional magnetic resonance imaging reveals the neural substrates of arm transport and grip formation in reach-to-grasp actions in humans. Journal of Neuroscience, 30(31), 10306-10323. https://doi.org/10.1523/jneurosci.2023-10.2010

Picking up a cup requires transporting the arm to the cup (transport component) and preshaping the hand appropriately to grasp the handle (grip component). Here, we used functional magnetic resonance imaging to examine the human neural substrates of...

Dissociable Neural Responses to Hands and Nonhand Body Parts in Human Left Extrastriate Visual Cortex (2010)
Journal Article
Bracci, S., Ietswaart, M., Peelen, M. V., & Cavina-Pratesi, C. (2010). Dissociable Neural Responses to Hands and Nonhand Body Parts in Human Left Extrastriate Visual Cortex. Journal of Neurophysiology, 103(6), 3389-3397. https://doi.org/10.1152/jn.00215.2010

Accumulating evidence points to a map of visual regions encoding specific categories of objects. For example, a region in the human extrastriate visua cortex, the extrastriate body area (EBA), has been implicated in the visual processing of bodies an...

Separate channels for processing form, texture, and color: Evidence from fMRI adaptation and visual object agnosia (2010)
Journal Article
Cavina-Pratesi, C., Kentridge, R., Heywood, C., & Milner, A. (2010). Separate channels for processing form, texture, and color: Evidence from fMRI adaptation and visual object agnosia. Cerebral Cortex, 20(10), 2319-2332. https://doi.org/10.1093/cercor/bhp298

Previous neuroimaging research suggests that although object shape is analyzed in the lateral occipital cortex, surface properties of objects, such as color and texture, are dealt with in more medial areas, close to the collateral sulcus (CoS). The p... Read More about Separate channels for processing form, texture, and color: Evidence from fMRI adaptation and visual object agnosia.

Separate processing of texture and form in the ventral stream: evidence from fMRI and visual agnosia (2009)

Real-life visual object recognition requires the processing of more than just geometric (shape, size, and orientation) properties. Surface properties such as color and texture are equally important, particularly for providing information about the ma...

Macaque neurophysiology and human neuropsychology results suggest that parietal cortex encodes a unique representation of space within reach of the arm. Here, we used slow event-related functional magnetic resonance imaging (fMRI) to investigate whet...

Optic ataxia is defined as a spatial impairment of visually guided reaching, but it is typically accompanied by other visuomotor difficulties, notably a failure to scale the handgrip appropriately while reaching to grasp an object. This impaired gras... Read More about Impaired grasping in a patient with optic ataxia: Primary visuomotor deficit or secondary consequence of misreaching?.
