Dorsal cochlear nucleus response properties following acoustic trauma: response maps and spontaneous activity.
Recordings from single neurons in the dorsal cochlear nucleus (DCN) of unanesthetized (decerebrate) cats were done to characterize the effects of acoustic trauma. Trauma was produced by a 250 Hz band of noise centered at 10 kHz, presented at 105-120 dB SPL for 4h. After a one-month recovery period, neurons were recorded in the DCN. The threshold shift, determined from compound action-potential ...
متن کاملSelective degeneration of synapses in the dorsal cochlear nucleus of chinchilla following acoustic trauma and effects of antioxidant treatment.
The purpose of this study was to reveal synaptic plasticity within the dorsal cochlear nucleus (DCN) as a result of noise trauma and to determine whether effective antioxidant protection to the cochlea can also impact plasticity changes in the DCN. Expression of synapse activity markers (synaptophysin and precerebellin) and ultrastructure of synapses were examined in the DCN of chinchilla 10 da...
متن کاملIntracellularly labeled fusiform cells in dorsal cochlear nucleus of the gerbil. I. Physiological response properties.
Fusiform cells in the dorsal cochlear nucleus (DCN) of barbiturate-anesthetized Mongolian gerbils were characterized physiologically and labeled with neurobiotin. This report is based on 17 fusiform cells for which there was reasonable confidence in the association between physiological data and recovered anatomy. The qualitative morphology of these cells was no different from that reported in ...
متن کاملIntracellular response properties of units in the dorsal cochlear nucleus of unanesthetized decerebrate gerbil.
Intracellular recording experiments on the dorsal cochlear nuclei of unanesthetized decerebrate gerbils were conducted. Acceptable recordings were those in which resting potentials were -50 mV or less and action potentials (APs) were > or = 40 mV. Responses to short-duration tones and noise, and to current pulses delivered via recording electrodes, were acquired. Units were classified according...
