  a. overproducing ACh receptors on muscles.
  b. reducing ACh function in the basal forebrain.
  c. reducing the number of ACh receptors on muscles.
  d. reducing ACh function in the dorsolateral pons.

Question 2

Match up the cholinergic fiber system with the correct role of that system in the control of behavior.
 
  a. Most CNS circuits that use ACh are inhibitory for learning.
  b. Cholinergic neurons in the dorsolateral pons are involved in the control of the electrical rhythms of the hippocampus.
  c. Cholinergic neurons in the medial septum are involved in the control of the electrical rhythms of the hippocampus.
  d. Cholinergic neurons in the basal forebrain are involved in the control of REM sleep.
  e. Cholinergic neurons in the medial septum facilitate learning.
