Neurons A, B, C, D, and E all synapse with Neuron F. Neurons A, C, and
E are inhibitory, and neurons B and D are excitatory. If neurons B and D
are activated but neurons A, C, and E are not, what is most likely to
happen to Neuron F?
a. It will fire because Neurons B and D will release transmitter substances
that will excite its postsynaptic membrane.
b. It will not fire, because it is inhibited by Neurons A, C, and E.
c. It will remain at rest because all neurons need to be stimulated by at least three other
neurons in order to fire.
d. It will fire because activation of Neurons B and D will cause the ion channels in it to open
and let in positively charged potassium ions.
e. It will not fire because all neurons, both inhibitory and excitatory, must be activated in
order for a synapse to be active.
a. It will fire because Neurons B and D will release transmitter substances that will
excite its postsynaptic membrane.
