This overview addresses Neurotransmitters, with particular emphasis on the role of neurotransmitters in enabling communication within the nervous system and their impact on sensation, movement, and emotion. We will explore key types of neurotransmitters, their synthesis, release, and receptor mechanisms. The lecture will also discuss how disruptions in neurotransmitter systems underlie major neurological and psychiatric disorders and how these insights inform treatment strategies. Finally, we will touch on advances that are leading to more personalized approaches in neuroscience and medicine.. Neurotransmitters are chemical messengers that enable communication between neurons and other cells, such as muscle or gland cells. They rapidly and precisely transmit signals across synapses within the brain and nervous system, underlying every sensation, thought, movement, and emotion. Neurotransmitters are crucial for actions, reflexes, mood regulation, learning, and memory. Understanding their function helps explain how the brain operates and why disruptions can lead to neurological and psychological disorders. Neurotransmitters are categorized by chemical structure and function. Excitatory ones like glutamate promote action potentials, while inhibitory ones such as GABA reduce neuronal firing. Dopamine regulates reward, motivation, and movement; serotonin influences mood, appetite, and sleep; acetylcholine is essential for muscle activation and cognition. Other neurotransmitters include noradrenaline,
