Outline
Physiology of Memory
Process:
long-term potentiation
Stress hormones
Where: Brain Structures
Hippocampus
Where the memories are processed

4. Stress Hormones & Memory
Heightened emotions (stress-related or otherwise) make for stronger memories
Hormones and neurotransmitters like Epinephrine act on brain centers in the brain
Extreme stress undermines learning and later recall
How does this apply to an exam?
OBJECTIVE 12| Discuss some ways stress hormones can affect memory.

5. Where Are Memories Stored?

6. Biological Forgetting Factors
Damage to the Hippocampus
Difficulty forming new memories
Neurotransmitters play a role
Acetylcholine
Alzheimer’s patients show low levels of this
Decay theory
Memories deteriorate because of the passage of time
Distractor Studies – information fades from STM
