Question

ipsp causes the membrane to get closer to threshold

true
false

Explanation:

Define IPSP function

Using the Action Potential Phases and Membrane Potential Values knowledge points
An Inhibitory Postsynaptic Potential (IPSP) is a local hyperpolarization of the postsynaptic membrane. This change moves the membrane potential further away from the threshold required to trigger an action potential, making the neuron less likely to fire.

Compare with EPSP

An Excitatory Postsynaptic Potential (EPSP) depolarizes the membrane, bringing it closer to the threshold. Since the statement claims that an IPSP causes the membrane to get closer to the threshold, the statement is false.

Answer:

• True
• False (Correct answer)
