Memory

Memory is the storage of information. Registration is the first step of forming new memories, and is followed by encoding (medial temporal lobe & amygdala) and consolidation. Retrieval of memories uses frontal subcortical systems.

 

Types of memory

Declarative Memory

Declarative memories enter consciousness and can be verbalized. They can be formed after a single encounter. Examples include:

 

Nondeclarative memory

Nondeclarative memories are largely unconscious and usualy require repetition for their strengthening. Examples include:

 

 

 

Short term memory

 

 

 

Long term memory

 

 

Cellular mechanisms of memory

Memory is the product of neural plasticity and biochemical storage. Many mechanisms are used, though synapses appear to be a key site of memory in the brain.
