Significance of forebrain structures in acoustically guided behavior in anurans.

In order to test the hypothesis that the forebrain is involved in controlling acoustically guided behaviour, we carried out behavioural studies in combination with brain lesions, neuroanatomical and electrophysiological experiments in males and females of different species of frogs. Whereas the dorsomedial pallium plays no or only a minor role, the striatum, the septum, and the preoptic area potentially influence the behaviour because they send parallel descending projections to different premotor and motor networks in the brainstem. These parallel projections may be the basis for the variability seen in the behaviour.
