2. Which then triggers the fusion of synaptic vesicles with the membrane, releasing neurotransmitters into the synaptic cleft where they bind to receptors on the postsynaptic neuron3. This generates a signal that can potentially trigger a new action potential in the postsynaptic neuron4. Finally, ...
When the calcium ions rush in, a chemical called a neurotransmitter is released into the synapse. The neurotransmitter binds with receptors on the neuron. ... If the K+ channels open, the neuron membrane becomes hyperpolarized, and inhibition occurs. The impulse isstopped dead if an action pote...
