Research

The nervous system is faced with the daunting task of integrating the different sensory cues into a coherent representation of the external world. I, in conjunction with a number of other faculty members here at Wake Forest, study the neural mechanisms responsible for providing this integrated representation. We use a variety of techniques ranging from single cell electrophysiology in awake behaving animals, to traditional psychophysical tasks involving humans.
