Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Canabanoids, like marijuana, block inhibitors for this neurotransmitter (resulting in a flood of it into parts of the brain)?

A	Dopamine
B	GABA
C	ACh
D	Glutamate

Explanation:

Detailed explanation-1: -The neurotransmitters involved include l‐glutamate, GABA, noradrenaline, dopamine, 5‐HT and acetylcholine.

Detailed explanation-2: -As lipids, endocannabinoids, mainly 2-AG, readily cross the membrane and travel in a retrograde fashion to activate CB1Rs located in the presynaptic terminals. Activated CB1Rs will then inhibit neurotransmitter (NT) release through the suppression of calcium influx.

Detailed explanation-3: -The drug activates CB1 receptors on GABA-ergic and glutamatergic neurons in the ventral tegmental area (VTA), inhibiting the activity of both. CB1 inhibition of GABA neurons promotes, and inhibition of glutamate dampens, VTA dopaminergic neurons’ activity and dopamine release in the NAc.

Detailed explanation-4: -The “cannabinoid” receptors in the brain-the CB1 receptors-outnumber many of the other receptor types on the brain. They act like traffic cops to control the levels and activity of most of the other neurotransmitters.
