WebJul 1, 2024 · An excitatory transmitter promotes the generation of an electrical signal called an action potential in the receiving neuron, while an inhibitory transmitter prevents it. Whether a neurotransmitter is excitatory or inhibitory depends on the receptor it binds to. WebA neurotransmitter may have an excitatory, inhibitory or modulatory effect on the target cell. The effect is determined by the receptors the neurotransmitter interacts with at the post-synaptic membrane. ...
WebAn excitatory transmitter promotes the generation an action potential in the receiving neuron, while an inhibitory transmitter prevents it. Modulatory Neurotransmitters can transmit messages to several cells simultaneously and also help to communicate with chemical transmitters. WebThere are two types of PSPs: Excitatory Post-synaptic Potentials (EPSPs) - conducive to action potential production •Acquisition of positive (+) charge in the post-synaptic neuron •Depolarize the neuron and help the axon hillock reach threshold Inhibitory Post-synaptic Potentials (IPSPs) – suppresses action potential production •Acquisition or maintenance …
