Fear conditioning to an acoustic stimulus produces increases in tone-evoked discharges of neurons in the medial division of the medial geniculate nucleus (MG). This study examined the responses of MG neurons to a conditioned tone presented in paradoxical sleep (PS). After 1 session of habituation to...
