We studied the pressure patterns used by domestic canaries (Serinus canaria) during song production, and their changes as the telencephalic nucleus HVC is cooled. We tested the hypothesis that the patterns emerge from the interaction of two times scales, one of which is affected by the temperature modulations. In particular, our model assumes that the pressure patterns are the solutions of a basic neural oscillator being driven by a temporal signal, which is affected by the thermal manipulations. Under this hypothesis, we investigate the changes in the forcing as a function of the temperature.
