Evolution of human speech and language - the role of FOXP2
We use a mouse model humanized for the transcription factor Foxp2, the only gene so far clearly linked to speech and language development in humans. The human version of Foxp2 leads to specific changes in cortico-basal ganglia circuits, affecting dopamine concentrations, dendrite lengths and synaptic plasticity as well as a faster shift from place-based to response-based learning. Currently, we focus on understanding the molecular and cellular mechanisms driving these changes.
