title: Post-movement processing in visual oddball task - Evidence from intracerebral recording.
abstract: OBJECTIVE
  To identify intracerebral sites activated after correct motor response during cognitive task and to assess associations of this activity with mental processes.
  
  
  METHODS
  Intracerebral EEG was recorded from 205 sites of frontal, temporal and parietal lobes in 18 epileptic patients, who responded by button pressing together with mental counting to target stimuli in visual oddball task.
  
  
  RESULTS
  Post-movement event-related potentials (ERPs) with mean latency 295 ± 184 ms after movement were found in all subjects in 64% of sites investigated. Generators were consistently observed in mesiotemporal structures, anterior midcingulate, prefrontal, and temporal cortices. Task-variant nonspecific and target specific post-movement ERPs were identified, displaying no significant differences in distribution among generating structures. Both after correct and incorrect performances the post-performance ERPs were observed in frontal and temporal cortices with latency sensitive to error commission in several frontal regions.
  
  
  CONCLUSIONS
  Mesiotemporal structures and regions in anterior midcingulate, prefrontal and temporal cortices seem to represent integral parts of network activated after correct motor response in visual oddball task with mental counting. Our results imply equivalent involvement of these structures in task-variant nonspecific and target specific processes, and suggest existence of common nodes for correct and incorrect responses.
  
  
  CONCLUSIONS
  Our results contribute to better understanding of neural mechanisms underlying goal-directed behavior.
