Significance of forebrain structures in acoustically guided behavior in anurans

In order to test the hypothesis that the forebrain is involved in controlli ng acoustically guided behaviour, we carried out behavioural studies in com bination with brain lesions, neuroanatomical and electrophysiological exper iments in males and females of different species of frogs. Whereas the dors omedial pallium plays no or only a minor role, the striatum, the septum, an d the preoptic area potentially influence the behaviour because they send p arallel descending projections to different premotor and motor networks in the brainstem. These parallel projections may be the basis for the variabil ity seen in the behaviour.
