HEMISPHERIC SPECIALIZATION AND COMMUNICATION

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This year, studies in our laboratory focused on the link between asymmetries in manual and vocal signals and neuroanatomical asymmetries in language homologs in the chimpanzee brain. We have found that manual gestures correlated with asymmetries in the inferior frontal gyrus and cingulate gyrus. We also found that handedness for tool use maps to the same brains regions as those associated with manual gestures. Lastly, we demonstrated in several studies that chimpanzees are sensitive to attentional cues in the execution of communicative signals.
