Although the cognitive sciences aim to ultimately understand behavior and brain function in
the real world, for historical and practical reasons, the field has relied heavily on artificial …

The current consensus divides primate cortical visual processing into two broad networks or
“streams” composed of highly interconnected areas (Milner and Goodale 2006, 2008; …

Brain rehabilitation and recovery for people with neurological disorders, such as stroke,
traumatic brain injury (TBI), and neurodegenerative diseases, depend mainly on …

The two visual systems hypothesis suggests processing of visual information into two distinct
routes in the brain: a dorsal stream for the control of actions and a ventral stream for the …

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 perception–action model proposes that vision-for-perception and vision-for-action are
based on anatomically distinct and functionally independent streams within the visual cortex …

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 …

Skilled grasp is a sensorimotor process requiring the brain to extract sensory cues from the
environment to shape a motor command. Although a large body of literature has focused on …

Posterior parietal cortex (PPC) plays an important role in the planning and control of goal-
directed action. Single-unit studies in monkeys have identified reach-specific areas in the …

In primates, neural mechanisms for controlling skilled hand actions primarily rely on
sensorimotor transformations. These transformations are mediated by circuits linking specific …
