N2 - The adaptive interactions with the outer world necessitate an effective connection between cognitive and executive functions. The current study presents one example of such connection. It was obtained during the investigation of late components of the intracerebrally recorded EEG responses evoked by the non-target stimuli of the oddball task. The data analyzed yielded an epileptic patient with chronic depth multilead electrodes implanted for diagnostic reasons into the gyrus cinguli anterior, the dorsolateral prefrontal cortex, the supplementary motor area, the primary motor cortex (M1), and the primary sensory cortex. The aim of the study was to ascertain whether the non-target variant of the task evoked any EEG response in the M1. The main result of the study was the finding of a response to non-target stimuli with a pronounced late component in three different loci of the M1 (the response recorded by three different electrodes; minimal distance between recording contacts 12 mm). The late component was almost perfectly synchronized in all three precentral loci and in one dorsolateral prefrontal locus. The mean amplitude of the component was 31.7 ± 2.5 ìV, the latency of its peak was 730 msec (the mean reaction time in the target trials was 474 msec). The finding is considered as direct evidence of a functional connection between the cognitive network, which underlay the accomplishment of the instructed experimental task and the particular locus in the M1, i.e. in the executive structure par excellence.
