The ACNL directed by Gavin M. Bidelman, Ph.D. uses a coordinated blend of techniques including evoked potentials, computational modeling, and psychoacoustics to decipher the neural basis of complex auditory perception. Current projects are focused on understanding the neurocomputations involved in generating basic psychoacoustic phenomena and during music and speech listening. Complementary work examines the neuroplasticity induced by listening experience and training (e.g. music lessons, bilingualism) and how these influences positively affect listening skills. O
