... Biosonar signals Flight behavior Foraging strategies Silent behavior Vocal behavior Many mammals rely on their visual systems to orient, navigate and forage. However, some species, like bats, dolphins and whales, have evolved specializations to actively probe their environments with sound...

... but not in the dorsal archistriatum. This pattern of findings raises the possibility that somatostatin-positive neurons in Ad may project to DM in both sexes. The overall pattern of somatostatin labeling is consistent with the idea that somatostatin may be involved with pro­ duction of learned vocal behavior in adult...

... requirements for motor production. Where there were size differences, they were restricted to regions primarily controlling vocal behavior acquisition/perception, suggesting that first time breeders need more brain space than experienced breeders to acquire crystallized song and/or acoustically perceive...
