neuroactive agents

Neuroactive agents are substances that influence the functioning of the nervous system by interacting with neurons or neurotransmitters, the chemical messengers that transmit signals in the brain and nerves. They can modify mood, perception, cognition, or physiological responses. These agents include medications, such as antidepressants or stimulants, as well as substances like caffeine or certain recreational drugs. By altering neural activity, neuroactive agents can help treat neurological and psychiatric disorders or produce specific mental and physical states. Understanding their effects requires knowledge of how they interact with the complex network of neurons and chemicals in the nervous system.
