Track 22: Neuropharmacology

Neuropharmacology

Neuropharmacology is the study of how drugs affect the nervous system, including the brain, spinal cord, and peripheral nerves. This field combines aspects of both pharmacology (the science of drugs and their effects) and neuroscience (the study of the nervous system) to understand how substances influence neural activity and, by extension, behavior, cognition, and physiological functions.

Neuropharmacology explores the mechanisms of action of various drugs, including their effects on neurotransmitter systems, receptors, ion channels, enzymes, and signaling pathways in the nervous system. It also studies how drugs can treat neurological and psychiatric disorders, ranging from pain and seizures to depression and schizophrenia.

Key Areas of Neuropharmacology

1. Neurotransmitters and Receptors
• Neuropharmacology often focuses on neurotransmitters—chemical messengers that transmit signals across synapses between nerve cells. Drugs can influence these signaling pathways by mimicking or modulating neurotransmitter systems.

Key Neurotransmitter Systems:

• Dopamine: Associated with mood, reward, and motor control. Dysregulation is involved in disorders like Parkinson’s disease, schizophrenia, and addiction.

Serotonin: Plays a role in mood, anxiety, sleep, and appetite regulation. Imbalances are linked to depression, anxiety disorders, and migraine
