Neural Regulation of Vision, Attention and Emotion in Nonhuman Primates
Office Phone: 


We are interested in understanding the neural circuits of visual perception, attention, and emotion in the nonhuman primates, and how we can regulate these basic functions through manipulating the activities of specific neurons or pathways.
To this end, we use several novel neuromodulation techniques including optogenetics, chemogenetics, in combination with electrophysiological and brain imaging techniques, to uncover how visual information is encoded in the brain, how attention modulates perception, how emotion interacts with cognition, and how these functions can be manipulated in the behaving monkeys. Eventually, we hope our findings can help to pave the way for extensively translational studies and clinical application in the near future.
