2. Memory and the Brain

3. Processing……….. Shallow processing- encoding on a basic level based on the structure or appearance of words Deep processing- encoding semantically, based on the meaning of the words; tends to yield the best retention

4. Areas of the brain related to memory Hippocampus- a neural center located in the limbic system; helps process explicit memories for storage. The Hippocampus is a temporary “loading dock” for memories before being transferred to another location in the brain. Ex: Removing a rat’s hippocampus 3 hours after it learns the location of food disrupts this process and prevents long term memory formation; removal 48 hours later does not…..

5. The Cerebellum & Basal Ganglia These areas help to form implicit memories We know about the cerebellum, but the basal ganglia helps us develop procedural memories for skills such as riding a bike

6. The amygdala! As you remember, the amygdala plays a large role in our emotions. Remember Amy Gdala?  In stressful situations, stress hormones trigger the amygdala and also memory formation. These memories during such situations can often be burned into our brains and create “flashbulb memories”. Ex: In a 2006 Pew survey, 95% of American adults reported they could remember exactly where they were when they first heard news about the 9/11 attacks.

7. Long Term Potentiation (LTP) LTP is an increase in a cell’s firing potential after brief, rapid stimulation. This is believed to be a neural basis for learning and memory.
