| Research Abstract |
In this study, we investigate whether mirror neurons exist in common marmosets (Callithrix jacchus). First we discovered cells responsive to other's grasping action from a posterior part of the superior temporal sulcus, then injected retrograde fluorescent tracer (CTB- Alexa555) into the region. One week later, by using a fluorescence stereomicroscope, we were able to identify the regions containing the labeled cells in the ventral premotor cortex. Finally, we implanted linear array multi-contact electrodes into both labeled regions in the ventral premotor cortex and tracer injection site in the superior temporal sulcus, and recorded multi-units under awake condition. We found a significant number of multi-unit in the ventral premotor cortex were mirror neurons which showed significant responses both when performing a grasping action and when observing the experimenter performing various grasping actions.
