WebChemical synapses are the most common type of synapse in the nervous system and are responsible for many aspects of neural communication, including sensory perception, motor control, and cognition. They can be excitatory or inhibitory depending on the type of neurotransmitter released and the receptors on the postsynaptic neuron. WebIn a chemical synapse, electrical activity in the presynaptic neuron is converted (via the activation of voltage-gated calcium channels) into the release of a chemical called a neurotransmitter that binds to receptors …
WebJun 8, 2024 · In a chemical synapse, the pre and post synaptic membranes are separated by a synaptic cleft, a fluid filled space. The chemical event is involved in the transmission of the impulse via release, diffusion, receptor binding of neurotransmitter molecules and unidirectional communication between neurons.
