Plasticity, memories, NMDA glutamate receptors Flashcards
1
Q
Types of memories
A
Declarative (consciously access) and non-declerative (body just knows)
2
Q
Where are memories stored in the brain
A
Hippocampus
3
Q
Hebb’s postulate
A
When axon of cell A is near enough to excite cell B and repeatedly takes part in firing it…1. Growth processes and metabolic change takes place in 1 or both cells…2. A’s efficiency to excite B is increased
4
Q
What do Hebbian synapses exhibit
A
NMDA receptor dependent LTP
5
Q
What are NMDA receptors
A
Voltage dependent, magnesium block, pore loop, glutamate
6
Q
How can the properties of AMPA and NMDA receptors be distinguished
A
Using selective agonists
7
Q
How does the brain encode memories?
A
LTP or LTP-like process
