Robert Kuba Filipkowski received his PhD at Nencki Institute in Warsaw, spent four years in Cold Spring Harbor Laboratory, NY, and is now a head of the Behavior and Metabolism Research Laboratory at Mossakowski Institute. At the lab, we investigate the ultrasonic vocalizations of mice and rats (relevant publications below). We have designed and developed new behavioral setups based on the playback of recorded vocalizations. It turns out rats emit a lot of vocalizations when presented with pre-recorded calls of other rats (see Olszyński et al. 2020). Particularly, we explore changes in the cardiovascular i.e. heart-rate, and behavioral parameters evoked by the playback during different states of the autonomic nervous system. Also, we describe new types of vocalizations as well as study and analyze exchange of vocalizations between couples and groups of rats as well as mice. Here, we investigate different types of vocalizations in search for their biological meaning and/or patterns of emissions and calls’ exchange. Our new project aims at establishing brain centers responsible for vocal ultrasonic exchange.

Research interests:

Behavior, language, stress, animal communication
