Cocaine-dependence and cocaine-induced paranoia and mid-latency auditory evoked responses and sensory gating.
Cocaine-dependence has been shown to affect the amplitudes of the P50 mid-latency auditory evoked response (MLAER) as well as P50 sensory gating. The effects on subsequent MLAERs (N100 and P200) have not been examined. The objective of the current study was to further assess the effects of chronic cocaine use on the P50, N100, and P200 components. Thirty-four, at least three weeks abstinent, co...
متن کاملMid-latency auditory evoked potentials during ketamine anaesthesia in humans.
We studied mid-latency auditory evoked potentials (MLAEP) during induction of general anaesthesia with ketamine 2 mg kg-1. MLAEP were recorded before, during and after induction of general anaesthesia on the vertex (positive) and mastoid (negative) positions. Latencies of the peak V, Na, Pa, Nb, P1 and amplitudes Na/Pa, Pa/Nb and Nb/P1 were measured. Fast-Fourier transformation was used to calc...
متن کاملAuditory Middle Latency Evoked Responses : A Standardizing Study Summary
5 1 PhD at USP/SP, member of the medical staff at the Odontomed Hospital. The presence of auditory middle latency evoked responses allows us to make an evaluation of the peripheral and central auditory system integrity , as well as the nucleus and auditory ways existing until the level of the thalamus-cortical region and primary auditory cortex. Aim: Our objective is to evaluate the presence or...

UNLABELLED The presence of auditory middle latency evoked responses allows us to make an evaluation of the peripheral and central auditory system integrity , as well as the nucleus and auditory ways existing until the level of the thalamus-cortical region and primary auditory cortex.

متن کاملSensory gating in rats: lack of correlation between auditory evoked potential gating and prepulse inhibition.
This study was designed to evaluate the possible similarities between two paradigms designed to measure sensory gating: (1) an auditory evoked potential (AEP), called the P50 gating paradigm; and (2) an acoustic startle (ASR), called the prepulse inhibition paradigm. These paradigms show a number of methodological, pharmacological, and neurobiological similarities, and they are both disturbed i...
