We are surrounded by a myriad of objects in the external world, and we survive in this world by successfully interacting with these objects. Consider driving a car, cooking in a kitchen, or socializing at a party. A fundamental building block of our daily activities is the ability to recognize objects and decide what actions to take based on them. Our lab focuses on elucidating the principles of neural computation underlying object recognition and decision making in the primate brain using monkey electrophysiology, human psychophysics, and computational modeling. The lab develops a variety of behavioral tasks that require subjects to judge the categories of visually presented objects, such as images of faces and animals.
