WebbThe synaptic potential in the motor neuron is called an inhibitory postsynaptic potential (IPSP) because it tends to move the membrane potential away from the threshold, thereby decreasing the probability of this neuron initiating an action potential. 6.6 Ionic Mechanisms for IPSPs Webb13 apr. 2024 · The inhibitory neuron falls under the central nervous system and they have a significant role to play in the human body. While the inhibitory transmitter is a transmitter that creates a signal called the ‘action potential’. The job of the transmitter is to prevent receiving the action potential.

"WebbThe formation of an action potential can be divided into five steps: (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached, all Na+ channels open and the membrane depolarizes. " - Inhibitory neuron fire action potential

This adding up of responses is called summation. Neurotransmitters thus facilitate rapid communication between neurons by changing the firing of the action potential. Other forms of summation include
