The division of cortical visual processing into distinct dorsal and ventral streams is a key
framework that has guided visual neuroscience. The characterization of the ventral stream …

Evidence for a dichotomy between the planning of an action and its on-line control in
humans is reviewed. This evidence suggests that planning and control each serve a …

We used functional magnetic resonance imaging (fMRI) to map the cortical representations
of executed reaching, observed reaching, and imagined reaching in humans. Whereas …

Research from macaque neurophysiology and human neuropsychology has implicated the
parietal cortex in the sensory control of action. Functional neuroimaging has been very …

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 …

In primates, control of the limb depends on many cortical areas. Whereas specialized
parietofrontal circuits have been proposed for different movements in macaques, functional …

The dorsal stream of visual information processing connecting V1 to the parietal cortex is
thought to provide a fast control of visually guided reaching. Important for this assumption …

Reaching toward a visual target involves at least two sources of information. One is the
visual feedback from the hand as it approaches the target. Another is proprioception from the …

Research on preparatory brain processes taking place before acting shows unexpected
connections with cognitive processing. From 50 years, we know that motor-related brain …

The medial parieto-occipital cortex is a central node in the dorsomedial visual stream.
Recent physiological studies in the macaque monkey have demonstrated that the medial …
