Research in my lab focuses on three categories: Vision, cognitive brain science, and neuronal prosthetics. I am interested in how visual single and population neurons (LFP) reflect visual perception. To achieve this, the response properties and mapping organizations of nerouns are meaured through the visual cortical areas as well as cortical depth. in sum, the long-term goal of my study is to design and implant sensory and cognitive neuronal prosthetics for patients.
