An Inhibitory Postsynaptic Potential

Multiple Choice

An inhibitory postsynaptic potential:

A) is produced by simultaneous increases in permeability to both Na⁺ and K⁺.
B) occurs when a ligand-gated ion channel increases its permeability to K⁺.
C) is a small depolarization in a postsynaptic cell.
D) can be summed with other IPSPs to trigger an action potential in the postsynaptic cell.
E) is produced by an increase in permeability to only Na⁺.
