Abstract
"Rats communicate extensively in the ultrasonic frequency range; ultrasonic vocalizations (USVs) occurring at 22 kHz serve an alerting function, whereas those occurring around 50 kHz have been proposed to reflect a state of positive affect. However, 50-kHz calls are acoustically heterogeneous and, not surprisingly, they also seem to differ in their behavioural significance. The first aims of this thesis were to identify subtypes of 50-kHz USVs, and determine how drug or social context alters their absolute and relative prevalence. These aims were addressed in Chapter 2, in which USVs emitted by adult rats were examined following amphetamine (AMPH) administration. A thorough analysis of over 20,000 USVs revealed that 50-kHz calls are comprised of at least 14 distinct call categories.
