Meta memory- Knowledge of our own memory

Technology by which we can check brain function

Computed tomography of brain helps us to see any unusual damage to brain.

Functional MRI- how different region of brain are working.

Biology of memory

LTP and glutamate-synaptic plasticity where a persistent strengthening of synapses based on recent patterns of activity occurs.

LTP and Hipocampus-a stable facilitation of synaptic potentials after high-frequency synaptic activity.

Memory deterioration- This is often normal with aging but could be observed in diseased young individuals.

Multiple Sclerosis- a chronic disease that affects the central nervous system causing poor coordination.

Alzheimer's diseases is a progressive disorder which can affects memory, thinking, and behavior

Common phenomenon observed

Encoding Specificity- Phenomenon of remembering something better when conditions are same as information was analysed.

TOT- Tip-of-tongue phenomenon is like you experience of knowing something but being unable to access

False memory-when our brain is traumatized, so cannot recollect memory right.

Eye witness testimony- primary example of it.

tragic event- This could lead into false sensations.

Amnesia-inability to remember the information.

Anterograde- where you can't form new memories after the event

Retrograde-loss of memory were formed before the event

Retrieval- it is referred as retention of stored memory

Relearning-a measure of how long it takes to learn something back from past knowledge.

Recognition-ability to notice info

Recall-ability to remember when asked

Storage

Rehearsal

Elaborative- when the stimulus maybe linked with other information.

Maintenance- repetition with little of no interpretation.

Long-term memory

Implicit Memory- unconscious awareness of a person.

Procedural memory- This is based on skills and tasked which are performed regularly.

Explicit Memory-Conscious awareness of a person.

Declarative Memory- This is based on facts and events only.

Sensory memory
