Practice question · Select all that apply
Select every statement that is TRUE about the limbic system.
Hints
- Two options are misconceptions - one about smell, one confusing hypothalamus with thalamus.
- Smell is the one sense that bypasses the thalamus, and sensory relay is the thalamus's job, not the hypothalamus's.
Show the answer
- C. The amygdala is central to fear.
- D. The hippocampus forms new memories while the hypothalamus regulates drives.
- E. Hippocampal damage leaves old memories intact.
Why
The hippocampus/hypothalamus division, the amygdala's fear role, and old-memory sparing are true. Smell bypasses the thalamus, and the hypothalamus regulates drives rather than relaying sensation - so those two are false.
