Neuronal synchronization in human parietal cortex during saccade planning.
Neuropsychological and neuroimaging studies have implicated the human posterior parietal cortex (PPC) in sensorimotor integration and saccade planning. However, the temporal dynamics of the underlying physiology and its relationship to observations in non-human primates have been difficult to pin down. Here we review some recent work that investigates the role of human parietal neuronal synchronization in the coding and updating of visuomotor representations in saccade and anti-saccade tasks. We also discuss this work in relation to findings made on different spatial and temporal scales in monkey and human posterior parietal cortex.
