Abstract/OtherAbstract:
|
In the present study, the possibility of component-specific self-regulation of the contingent negative variation (CNV) and the functional significance of the iCNV (initial or early CNV component) and tCNV (terminal or late CNV component) were investigated in twenty-four healthy volunteers. The subjects were able to achieve control over a particular CNV component within four sessions. Regulation of the tCNV was more successful than for the iCNV. Specific control over iCNV was associated with strategies mainly related to the pre-stimulus interval or the warning stimulus (S1), while regulation of the tCNV was assigned to activities during the whole interstimulus interval or around the imperative stimulus (S2). It can be concluded that component-specific regulation of the CNV can be used in studies of the psychophysiological meaning of this potential, representing different stages of information processing. The role of cortical pre-activation in the generation of the iCNV and the phasic performance-directed activation of the tCNV can be hypothesized. |
