WebThe acoustic startle response (ASR) is a withdrawal reflex to sudden or noxious auditory stimuli and, most importantly, an unbiased measure of emotional processing of appetitive … WebDec 1, 1997 · This review describes the neuronal mechanisms underlying the mediation and modulation of the acoustic startle response (ASR) in rats. The combination of anatomical, physiological and behavioral methods has identified pathways which mediate and modulate the ASR.

WebOct 24, 1994 · The neural circuitry underlying this kind of modulation of the ASR is only partly understood. It has been shown that the central nucleus of the amygdala (cA) and its efferent pathway to the caudal pontine reticular nucleus (PnC), an essential part of the primary startle circuit, is important for the sensitization of the ASR. WebAn acoustic short circuit is a phenomenon in which sound waves interfere in such a way that both waves are canceled out.This occurs when the peak of one wave aligns with the … they were very relaxed
