The ethanol does not excite the postsynaptic neuron as glutamate would do. However, because the ethanol is now blocking the receptors, glutamate can no longer cause the generation of an action potential in the postsynaptic neuron. Here we see a presynaptic neuron that releases GABA as a neurotransmitter. The postsynaptic neuron therefore has receptors for GABA. In the absence of ethanol, an action potential arriving in the presynaptic neuron will trigger the release of GABA into the synapse.

But excessive drinking — either steadily or in the form of binge drinking sessions — can have a more serious, long-term effect on brain function. “For starters, alcohol slows down the neurotransmitter GABA, and that’s what drives the sluggish movement, slurred speech, and slower reaction time in someone who’s intoxicated,” said Pagano. At the same time, Pagano added, alcohol speeds up a neurotransmitter called glutamate, which is responsible for regulating dopamine in the brain’s reward center.

  • Your whole body absorbs alcohol, but it really takes its toll on the brain.
  • You may wake up the next day unaware of things that you did or said, or you could even wake up in a strange place and not remember anything about how you got there.

In advanced stages, the brain shuts down completely, leaving the person in a coma. The more alcohol you consume, the higher your risk for permanent brain damage. As adolescents do not have fully developed brains, excessive drinking can disrupt brain development, structure, and function. Low GABA levels could be one reason why adults and adolescents react to alcohol effects in such different ways. Regardless of age, in terms of neurobiology, alcohol promotes sedation, controlled by GABA in the brain, and blocks excitation, controlled by glutamate in the brain. The limbic system consists of areas of the brain called the hippocampus and septal area.

Over the course of one night of significant alcohol use, a person can expect to experience inhibited decision-making ability, motor function, and speech due to the way that alcohol suppresses neurons in the brain. Also, a person will possibly experience drastic mood swings between euphoria, depression, and an unpredictable number of other feelings. Finally, if enough alcohol is consumed it could affect a person’s memory.

“I’ve seen cases where I wouldn’t recognize a patient based on how they’re acting.” Brain damage can also be caused by cirrhosis of the liver, another common complication of long-term, heavy drinking. An example of an inhibitory neurotransmitter is GABA, which reduces energy levels and calms everything down. Drugs like Xanax and Valium increase GABA production in the brain, resulting in sedation.
