Steroid-Dependent Auditory Plasticity Leads to Adaptive Coupling of Sender and Receiver
Joseph A. Sisneros,*Paul M. Forlano,David L. Deitcher,Andrew H. Bass
For seasonally breeding vertebrates, reproductive cycling isoften coupled with changes in vocalizations that function incourtship and territoriality. Less is known about changes inauditory sensitivity to those vocalizations. Here, we show thatnonreproductive female midshipman fish treated with either testosteroneor 17ß-estradiol exhibit an increase in the degreeof temporal encoding of the frequency content of male vocalizationsby the inner ear that mimics the reproductive female's auditoryphenotype. This sensory plasticity provides an adaptable mechanismthat enhances coupling between sender and receiver in vocalcommunication.
