Excitatory Synapse

An excitatory synapse is the site of communication between neurons where an impulse is transmitted from one neuron to another, usually by a chemical neurotransmitter released by the axon terminal of the presynaptic neuron. This neurotransmitter then acts on the postsynaptic neuron, causing its membrane to depolarize, and potentially producing an action potential in that neuron. In our project, we will analyze the structure of an excitatory synapse, the steps involved in excitatory signal transmission, the neurotransmitters that characterize these synapses, and other important aspects and applications of this topic.
