Research Topic: Noise trauma induced reorganization of the auditory cortex
Long-Term Goal: To understand tinnitus at the level of neural circuits (auditory processing). Our approach offers a rather unique opportunity to sample activity within large-scale representations and local populations of neurons and, in turn, will reveal precisely how A1 micro-circuits are affected by traumatic insult to peripheral sensory organs. Thus, I intend on using this approach to build a more comprehensive understanding of how cortical micro-circuits change as a result of noise trauma.
