Alpha-band desynchronization in human parietal area during reach planning

Highlights • Posterior parietal cortex (PPC) uses frequency-specific dynamics in planning visuo-motor goal-directed tasks. • Upper alpha band PPC activity codes for preparing goal-directed actions, whereas lower alpha band PPC activity reflects general task demands and attentional processes that are...

Description
Summary:Highlights • Posterior parietal cortex (PPC) uses frequency-specific dynamics in planning visuo-motor goal-directed tasks. • Upper alpha band PPC activity codes for preparing goal-directed actions, whereas lower alpha band PPC activity reflects general task demands and attentional processes that are not task-specific. • PPC activates earlier in a goal-directed action.
