Satoko joins the Graybiel lab with a PhD in Medicine from Hokkaido University, Japan, where she studied the neuronal mechanism of set-shifting in the dorsolateral prefrontal cortex of macaque monkeys. Here at the Graybiel lab, in collaboration with Ken Amemori, she is studying cortico-basal ganglia circuits of non-human primates underlying conflict decision-making using neurophysiological, anatomical, and virus-based manipulation techniques.
