Happiness Booster

The answer lies with

DOPAMINE

What is Dopamine?

a neurotransmitter that activates pleasure centers in certain parts of the brain

helps regulate movement and emotional responses, motivate us

How?

caffeine increases level of dopamine (released from prefrontal cortex)

causes reabsorption of dopamine in the body to be slower

A deficiency of dopamine is likely responsible for the loss of pleasure and motivation found in major depression

Parkinson Diseasea disorder of the brain that

leads to shaking (tremors) and difficulty with walking, movement, and coordination.

participants who carried types of a specific gene — called GRIN2A — received neuroprotective benefits from coffee against Parkinson’s

Caffeine act as antagonist to the A2A receptor, blocking its binding site, rendering it inactive

Made on mice. Inject MPTP to mice pre-treated with caffeine

Recent Research shows:

Extra:

Why don’t you feel sleepy after taking coffee?

Woke up >> neurons produce

adenosine >> adenosine receptor at CNS monitor the action >> caffeine as a block of

wood >> bind at there and doesn’t activate the

receptor >> no stimulant will be

send to brain

Improve on Short-Term

Memory

TWO TYPES Working memory Short-term storage memory

THE STUDIES Some of the studies indicate that drinking coffee can improve short term memory Reaction times Reverse symptoms of Alzheimer's disease Regular consumption of caffeine

How it may work?

• Adenosine and Caffeine• Improving alertness temporarily• Increased neuron firing

HOW IT MAY WORK? Adenosine and Caffeine Improving alertness temporarily Increased neuron firing

• Adrenal gland –produces adrenaline

Adrenal gland –produces adrenaline

Increased Attention andMemory Performance

Feel Fresh and not Sleepy
