Prefrontal theta oscillations associated with hand movements triggered by warning and imperative stimuli in the monkey.


In order to investigate the functional significance of theta oscillations in the brain, we recorded the cortical field potential in monkeys engaged in a visually-initiated hand movement task. In each trial a warning signal (S1) was followed 3 s later by an imperative signal (S2) to which the monkey had to respond to get a reward. The theta power in the… (More)
