Reduced activation of midline frontal areas in human elderly subjects: a contingent negative variation study.

Contingent negative variation (CNV) was recorded from electrodes F7, F3, Fz, F4, F8, T7, C3, Cz, C4, T8, P7, P3, Pz, P4 and P8 in 19 young (mean age: 23 years) and 15 elderly (mean age: 66 years) healthy right-handed subjects, using a S2-choice paradigm. Young subjects showed early peak negativity shortly after the warning stimulus over mid-frontal areas, whereas for the remaining electrodes the negativity increased continuously. The amplitude of the early CNV was selectively reduced in elderly subjects over midline but not lateral frontal areas. We conclude that the activation of frontal midline areas as pre-supplementary motor area or anterior cingulate might be impaired in higher age.[1]
