Dopamine is a neurotransmitter that plays a crucial role in reward, motivation, and mood regulation.

Benzodiazepines work by enhancing the inhibitory effects of GABA, a neurotransmitter that promotes relaxation and reduces anxiety.

Glutamate is the primary excitatory neurotransmitter in the brain and plays a crucial role in memory formation, learning, and cognition.

SSRIs work by blocking the reuptake of serotonin, thereby increasing its availability in the synaptic cleft and enhancing its neurotransmission.

Melatonin is a hormone produced by the pineal gland and plays a crucial role in regulating the body's sleep-wake cycles.

Antipsychotics work by blocking dopamine receptors, particularly in the mesolimbic and mesocortical pathways, thereby reducing dopaminergic activity.

Acetylcholine is the primary neurotransmitter responsible for neuromuscular transmission, enabling communication between nerves and muscles.

Opioids work by binding to opioid receptors in the brain and spinal cord, reducing the perception of pain and producing a sense of euphoria.

Noradrenaline, also known as norepinephrine, plays a crucial role in regulating heart rate, blood pressure, and attention.

Stimulants work by blocking the reuptake of dopamine, leading to increased levels of dopamine in the synaptic cleft and enhanced dopaminergic signaling.

Leptin is a hormone produced by fat cells that plays a crucial role in regulating appetite and energy expenditure.

Anticonvulsants work by increasing the release of GABA, thereby enhancing inhibitory neurotransmission and reducing neuronal excitability.

Histamine is a neurotransmitter involved in various physiological functions, including the regulation of body temperature.

Hallucinogens work by binding to serotonin receptors, particularly the 5-HT2A receptor, leading to alterations in perception, mood, and consciousness.

Oxytocin is a neurotransmitter and hormone that plays a crucial role in social bonding, reproduction, and lactation.
