Bio:

visual neurophysiology and perception <p> Our research focuses on visual perception and neurophysiology. In particular, we are interested in cortical dynamics, circuitry, function, and mathematical modeling of the visual system. The main methods in the laboratory include multi-electrode recordings from single neurons, as well as intrisic and voltage senstive dye imaging of visual cortex. <p> We also have an interest in developing novel technologies to record and stimulate from large neuronal populations for use in prostheses. <p> For a detailed description of our research visit: http://manuelita.psych.ucla.edu/
