how these changes are stored and subsequently reactivated
any pathological loss of memory
What are conditioning types of learning and memory?
What are spatial types of learning and memory?
What is declarative memory?
Declarative memory is explicit.
What is procedural memory?
Procedural memory is implicit.
What are declarative types of learning and memory?
What is classical conditioning?
a neutral stimulus is paired with an unconditioned stimulus to elicit a conditioned response
What does operant condition deal with?
rewards and punishments
What is an engram?
a unit of memory
What did Lashley conclude?
Memory is not localized anywhere in the brain, but it is widely distributed throughout the cortex.

Response learning and habit formation
Memory for experiences with emotional significance
Episodic memory components are lost when prefrontal cortex is damaged
- Deficits in memory for temporal order of events

Two things that we need to know about LTP
1. a method at the cellular level to try and understand how memory takes place.
2. it takes place in the hippocampus
