Prehension, the capacity to reach and grasp, is the key behavior that allows humans to
change their environment. It continues to serve as a remarkable experimental test case for …

The concept of affordances indicates “action possibilities” as characterized by object
properties the environment provides to interacting organisms. Affordances relate to both …

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 …

Three-dimensional (3D) shape is important for the visual control of grasping and
manipulation and for object recognition. Although there has been some progress in our …

The cortical visuomotor grasping circuit, comprising the anterior intraparietal area (AIP),
ventral premotor (PMv), and primary motor cortex (M1) allows transformation of an object's …

Understanding actions of conspecifics is a fundamental social ability depending largely on
the activation of a parieto-frontal network. Using functional MRI (fMRI), we studied how goal …

We combined bifocal transcranial magnetic stimulation (TMS) and diffusion tensor imaging
(DTI) tractography to investigate in humans the contribution of connections originating from …

Background Almost 15 years after its formulation, evidence for the neuro-functional
dissociation between a dorsal action stream and a ventral perception stream in the human …

In humans, both clinical and functional imaging studies have evidenced the critical role
played by the posterior parietal cortex, and particularly by the anterior intraparietal area …

The act of reaching to grasp an object requires the coordination between transporting the
arm and shaping the hand. Neurophysiological, neuroimaging, neuroanatomic, and …
