The neural basis of visually guided behavior.

A nimals see things and then act on the ft basis of what they see. What chain of events connects some key stimulus with a specific fixed pattern of responses? In recent years workers in several laboratories have sought by many different means to analyze the nerve mechanisms by which animals interpret sensory. signals and select the most ap­ propriate response. The most effective way to understa...

Cortical temporal dynamics of visually guided behavior.

Little is known about the temporal dynamics of cortical activation during visually guided behavior. We measured changes in brain activity in human posterior parietal cortex (PPC) and premotor cortex (PMC) during saccades and visually guided reaching using magnetoencephalography (MEG) and novel time-frequency reconstructions of MEG (tfMEG) data. Results indicate that early high-gamma activity ov...

Parieto-frontal connectivity during visually guided grasping.

Grasping an object requires processing visuospatial information about the extrinsic features (spatial location) and intrinsic features (size, shape, orientation) of the object. Accordingly, manual prehension has been subdivided into a reach component, guiding the hand toward the object on the basis of its extrinsic features, and a grasp component, preshaping the fingers around the center of mas...
