title: Acute tolerance to ethanol on the release of acetylcholine from the cat cerebral cortex.
abstract: Ethanol (1 g/kg, iv) produced a peak depression of acetylcholine release from the cat sensorimotor cortices within 30 min of the ethanol administration but recovery to control levels occurred in the following 30 min. However, the concentrations of ethanol in the blood and in the solution bathing the cortex remained stable during this recovery period. This example of acute tolerance to ethanol is possibly related to the well-known acute tolerance that develops to the behavioural effects of ethanol.
