AP PSYCHOLOGY

Detailed explanation-1: -Dopamine. Dopamine plays a role in your body’s reward system, which includes feeling pleasure, achieving heightened arousal and learning. Dopamine also helps with focus, concentration, memory, sleep, mood and motivation.

Detailed explanation-2: -Gamma-aminobutyric acid (GABA) is a neurotransmitter, a chemical messenger in your brain. It slows down your brain by blocking specific signals in your central nervous system (your brain and spinal cord). GABA is known for producing a calming effect.

Detailed explanation-3: -GABA, a major inhibitory neurotransmitter, is believed to play an important role in memory – it slows down the rate at which neurons fire, preventing overstimulation. Altered levels of GABA have been reported in depression, anxiety, neurodegenerative disorders like Alzheimer’s, and normal ageing.

Detailed explanation-4: -Glutamate: The most plentiful neurotransmitter found in the nervous system, glutamate plays a role in cognitive functions such as memory and learning.

Detailed explanation-5: -GABA is the main inhibitory neurotransmitter of the CNS. It is well established that activation of GABA(A) receptors favors sleep.
