Question

Quizplus · Accepted Answer

High doses of alcohol are most likely to exert inhibitory effects on the production of action potentials by decreasing the excitability and responsiveness of neurons, leading to a decrease in neurotransmitter release and synaptic transmission, and ultimately, to a slowing down of neural activity. This is why alcohol is known to have sedative and hypnotic effects, which can impair cognitive and motor functions, as well as affective and social behaviors. However, at very high concentrations, alcohol may also cause some excitatory effects by disrupting the balance between inhibitory and excitatory neurotransmitters, such as GABA and glutamate, leading to an overactivation of some brain regions and a paradoxical stimulation in some individuals. Nonetheless, the overall effect of alcohol on the production of action potentials is inhibitory.
