Increased in dopamine ruse and makes person more conscious.

Stimulants- Anything that can stimulate nervous system

Cocaine- It is most powerful natural stimulant which can make person euphoric and enhance mental and physical capacity.

A person needs 8 hrs of sleep to function well on average.

Psychedelics- They are the hallucinogenic drugs

LSD- Chemically synthesised drug which binds to specific brain cell receptors and alters how the brain responds to serotonin,

Memory overtime when you grow-up

Knowledge and related inferential processes, spanning from simple types of perception to complex forms of thinking, are referred to as cognition.
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

Smell
Touch
Taste
Sound
Sight

Short-term memory
