Alcohol and Neurotransmitter Interactions

Alcohol and Neurotransmitter Interactions C. F ERNANDO V ALENZUELA , M.D., P H .D. Evidence suggests that alcohol affects brain function by interacting with multiple neurotransmitter systems, thereby disrupting the delicate balance between inhibitory and excitatory neurotransmitters.

Neurons, Brain Chemistry, and Neurotransmission

Do all neurotransmitters affect a neuron in the same way? No, the neurotransmitters glutamate and GABA have opposite effects on the neuron's activity.

Neurotransmission: "Muscle Messages"

The neurotransmitters travel to the neurotransmitter receptors on the muscle cell. The nerve cell gets excited. When it reaches the axon terminal, neurotransmitters are released.
