Male rats emit aversive 44-kHz ultrasonic vocalizations during prolonged Pavlovian fear conditioning

2023-04-08

Abstract excerpt

Rats are believed to communicate their emotional state by emitting two distinct types of ultrasonic vocalizations. The first is long “22-kHz” vocalizations (>300 ms, <32 kHz) with constant frequency, signaling aversive states and the second, is short “50-kHz” calls (<150 ms, >32 kHz), often frequency-modulated, in appetitive situations. Here we describe aversive vocalizations emitted at a higher pitch by male Wist...
