Question

Quizplus · Accepted Answer

The hippocampus is a crucial brain region for the formation of new long-term memories. If the tumor is affecting the ability to form new long-term memories, it is likely that the hippocampus is being impacted. The thalamus is involved in relaying sensory information to different areas of the brain, but is not closely tied to memory formation. The hypothalamus is involved in regulating bodily functions and behavior, but is also not closely tied to memory formation. The basal ganglia is involved in motor control and reward processing, but again, is not closely tied to memory formation.
