THE BASIC PATTERN OF ACTIVATION IN MOTOR AND SENSORY TEMPORAL TASKS -POSITRON-EMISSION-TOMOGRAPHY DATA

Positron emission tomography (PET) data were obtained from subjects pe rforming a synchronization task (target duration 2700 ms). A conjuncti on analysis was run to identify areas prominently activated both in th is task and in a temporal generalization task (target duration 700 ms) used previously. The common pattern of activation included the right prefrontal, inferior parietal and anterior cingulate cortex, the left putamen and the left cerebellar hemisphere. These areas are assumed to play a major role in time processing, in relation to attention and me mory mechanisms. (C) 1997 Elsevier Science Ireland Ltd.
