Description:
Slow shifts in brain potential (commonly called the contingent negative variation), obtained during a warned reaction-time task with a foreperiod of 1 second, were compared with waveforms synthesized by the addition of separately obtained potentials associated with individual (nonpaired) sensory stimuli and self-initiated motor movements. The synthesized waveforms match closely the actual contingent negative variation, suggesting that it is constituted largely of separate, noncontingent elements related to sensory and motor processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rohrbaugh, J W -- Syndulko, K -- Sanquist, T F -- Lindsley, D B -- New York, N.Y. -- Science. 1980 Jun 6;208(4448):1165-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375925" target="_blank"〉PubMed〈/a〉
