Dopamine is a neurotransmitter that plays a crucial role in the brain's reward system, mediating feelings of pleasure and motivation.

GABA (gamma-aminobutyric acid) is the main inhibitory neurotransmitter in the central nervous system, responsible for calming and reducing neuronal activity.

Serotonin is a neurotransmitter associated with mood regulation, sleep cycles, and appetite control.

Norepinephrine is involved in regulating attention, arousal, and focus, as well as modulating mood and motivation.

Acetylcholine is the primary neurotransmitter involved in neuromuscular communication, enabling the transmission of signals from neurons to muscles.

Glutamate is the primary excitatory neurotransmitter in the central nervous system, facilitating communication between neurons and playing a crucial role in learning and memory.

Norepinephrine is involved in the modulation of fear, anxiety, and stress responses, as well as arousal and attention.

Dopamine plays a central role in the brain's reward system, mediating feelings of pleasure, motivation, and reinforcement.

Epinephrine (adrenaline) is a neurotransmitter and hormone that is released in response to stress, increasing heart rate, blood pressure, and preparing the body for a fight-or-flight response.

GABA is the primary inhibitory neurotransmitter in the central nervous system, reducing neuronal activity and playing a crucial role in regulating brain excitability.

Norepinephrine is involved in modulating attention, focus, and working memory, as well as arousal and motivation.

Serotonin plays a crucial role in regulating mood, sleep-wake cycles, and appetite.
