Essential Task: Physiology of Memory Process: Where: Brain Structures Outline Physiology of Memory Process: long-term potentiation Stress hormones Where: Brain Structures Hippocampus Where the memories are processed
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.
Where Are Memories Stored?
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
