Neural correlates of temperature coupling in the vocal communication system of the gray treefrog (Hyla versicolor).
The central nervous system of the gray treefrog includes a class of auditory neurons which respond selectively to particular rates of amplitude modulation. When body temperature is increased, the temporal tuning of these neurons shifts to higher rates of modulation. This shift in tuning parallels the temperature-dependent shift in the trill rate in the male's mating call, thus constituting the neural correlate of temperature coupling between the female's behavioral selectivity and the temporal signal characteristics in the male's call.
