Learning and memory Flashcards
1
Q
The ____ studies were a breakthrough in human functional brain mapping
A
Penfield studies
2
Q
Amnesia patients showed the role of ______ lobe in memory
A
temporal (note that the hippocampus and amygdala are inside the temporal lobe)
3
Q
What are the two divisions of memory
A
Declarative memory
Procedural memory
4
Q
Decarative memory
A
- explicit memory
- memory of places, events facts and people
- temporal lobe
5
Q
Procedural memory
A
- implicit memory
- Perceptual motor learning and mental operations
- Long term (riding a bike)
- does not depend on structure of temporal lobe
- process of storage unkown (could possibly be the striatum)
6
Q
What are the three major synaptic pathways of the hippocampus
A
- Perforant-pathway- Entorhinal cortex to granele cells of the dentate gyrus (DG)
- Mossy-fiber pathway- Dentate gyrus (DG) to the CA3
- Schaffer collateral pathway- CA3 cells to CA1
7
Q
Hebb’s rule
A
-Neurons that fire together wire together
- As neurons continue to fire on the same sequence the same presnaptic firing is able to creater a creater postsynaptic firing. This leads to a long synapse that can last minutes, days, etc. This is called long term potentiation.
- The increase synapses lead to long term potentiation (LTP) which thus leads to more connections (synaptic plasticity).
8
Q
_____ receptors in the hippocampus induce LTP
A
NMDA
9
Q
NMDA and AMPA are both ___ receptors
A
Glutamate
