Motor imagery (MI) or the mental simulation of action is now increasingly being studied
using neuroimaging techniques such as positron emission tomography and functional …

The concept of affordances appeared in psychology during the late 60s as an alternative
perspective on the visual perception of the environment. It was revolutionary in the intuition …

Mountcastle and colleagues proposed that the posterior parietal cortex contains a
“command apparatus” for the operation of the hand in immediate extrapersonal space …

Gras** requires translating object geometries into appropriate hand shapes. How the
brain computes these transformations is currently unclear. We investigated three key areas …

Our human sense of touch is most highly developed in the hand where it serves a cognitive
function when experiencing objects in the world, and guides the skilled movements of the …

The human hand is unique in the animal kingdom for unparalleled dexterity, ranging from
complex prehension to fine finger individuation. How does the brain represent such a …

Despite recent advances in decoding cortical activity for motor control, the development of
hand prosthetics remains a major challenge. To reduce the complexity of such applications …

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

Prehension, the capacity to reach and grasp objects, comprises two main components:
reaching, ie, moving the hand towards an object, and gras**, ie, sha** the hand with …
