Abstract
Unilateral basal forebrain (BF) stimulations were delivered during slo w-wave sleep (SWS) while multi-unit recordings were performed bilatera lly in the auditory cortex. Ten tone presentations were followed by 10 pairing trials between BF stimulation and tone. Non-awaking BF stimul ations facilitated the tone-evoked responses ipsilaterally only. Atrop ine blocked the facilitation of the ipsilateral evoked responses obser ved after pairing in wakefulness. Thus, non-awaking cholinergic input can enhance cortical responsiveness during SWS.
