8. Synaptic Inhibition

Question 1

EPSP makes the postsynaptic cell to depolarize and become more likely to fire an action potential.

Answer 1

EPSP makes the postsynaptic cell to depolarize and become more likely to fire an action potential.

Question 2

Inhibitory PSP makes postsynaptic cell less likely to fire action potential. It can be inhibited through ion channels

1) Increase in potassium permeability leads to a decrease in membrane potential
2) Increase in Chlorine takes the membrane potential towards an equilibrium potential for Cl.

Answer 2

Inhibitory PSP makes postsynaptic cell less likely to fire action potential. It can be inhibited through ion channels

1) Increase in potassium permeability leads to a decrease in membrane potential
2) Increase in Chlorine takes the membrane potential towards an equilibrium potential for Cl.
