Inhibitory Signal

A single neuron can receive thousands of signals from other cells at once. Some push it toward firing, while others hold it back or regulate how much the excitatory signals count. The neuron is constantly combining these inputs before it “decides” whether to send an action potential of its own. This process is called synaptic…

Neurons are constantly receiving signals from other cells, and those signals come in two broad flavors. An excitatory signal makes a neuron more likely to fire an action potential. An inhibitory signal makes it less likely. Excitatory inputs usually produce an excitatory postsynaptic potential, or EPSP, and inhibitory inputs usually produce an inhibitory postsynaptic potential,…
