The role of frontal lobe networks in cognitive control of monkey vocalizations
Final Report Abstract
We were able to successfully establish the marmoset monkeys as a suitable animal model to study neuronal networks underlying cognitive control of vocal behavior. We revealed that the vocal behavior of marmoset monkeys seems to be controlled by a combination of flexible and more rigid mechanisms. We show that marmoset monkeys are able to call on command in response to arbitrary visual cues suggesting that the critical preadaptation being crucial for the evolution of human speech in the primate lineage, namely volitional control over the vocal apparatus exist in marmoset vocal behavior. Using the neurophysiological recording system, which has been established in my lab, we are now ideally positioned to investigate the neural substrate underlying cognitive vocal motor control in the next years.
