How does anesthesia inhibit neurons
WebResearch in rodents and primates has shown that moderate to high doses of MDMA, given twice daily for four days, damages nerve cells that contain serotonin. 10,12 MDMA-exposed primates showed reduced numbers of serotonergic neurons 7 years later, indicating that some of MDMA’s effect on the brain can be long lasting. 11 MDMA has additional ...

Previous work by the same team 2 … WebGABA is the primary inhibitory neurotransmitter, which means it decreases the neuron's action potential. When the action potential drops below a certain level, known as the threshold potential, the neuron will not generate action potentials and thus not excite nearby neurons. The nucleus of a neuron is located in the cell body.
