Intense noise-induced apoptosis in hair cells of guinea pig cochleae.

abstract：CONCLUSION:GABA-mediated inhibition is responsible for the duration tuning in the inferior colliculus (IC) of guinea pigs, a non-echo-locating mammal. Duration tuning in this species is better demonstrated in an appropriate short time window. OBJECTIVES:To investigate the role of GABA-mediated inhibition in duration t...
