How do we recognize objects and able to name them appropriately? Using psychophysics and neuroimaging techniques, my lab aims to understand the neural mechanisms of object recognition. This is a challenging project, given the sheer amount—87 billions—of neurons in the human brain.  We believe that the columnar (~0.5 mm in monkey and ~1.0 mm in human) or micro columnar serve as the basic functional units for processing biologically meaningful properties, including object recognitions. Currently, our lab is developing high-resolution fMRI techniques to investigate these questions.
