A) Atropine produces amnesic effects.

D) Alzheimer's disease is associated with a loss of cholinergic neurons in the forebrain.

Question

Quizplus · Accepted Answer

The statement that acetylcholine release is inhibited in prefrontal cortex when animals are presented with a sensory stimulus is false. In fact, acetylcholine release is increased in the prefrontal cortex during attention-demanding tasks and is thought to play a critical role in cognitive processes such as attention, learning, and memory. Atropine and scopolamine are both anticholinergic drugs that block the action of ACh, leading to amnesic effects. Alzheimer’s disease is characterized by a loss of cholinergic neurons in the forebrain, which is thought to contribute to the cognitive deficits observed in the disease.
