The closed-circuit TV-electroencephalogram (CCTV-EEG) of a 6-year-old
boy revealed central mid-temporal spikes (CMTS) triggered by blinking.
The spikes occurred spontaneously, as well as reflexly, following the
blinks by 100-200 msec. Triggered spikes occurred in the light and da
rk and also while awake and drowsy. However, spontaneous spikes, not t
riggered by blinks, also occurred in drowsiness. These findings demons
trate activation of CMTS by an endogenous behavior (blinking).
