WebFeb 9, 2024 · Neurotransmitters are chemical messengers that are released from a synaptic vesicle into the synapse by neurons. Some neurotransmitters act by making the neuron more negatively charged so less likely to fire. This is an inhibitory effect. This is the case for serotonin. Inhibitory neurotransmitters are generally responsible for calming the mind WebNeural Transmission. The function of a neuron is to transmit information within the nervous system. Neural transmission occurs when a neuron is activated, or fired (sends out an electrical impulse). Activation (firing) of the neuron takes place when the neuron is stimulated by pressure, heat, light, or chemical information from other cells.
