What are neurotransmitters?

Neurotransmitters are indeed chemicals that transmit signals from one neuron to another, playing a crucial role in the communication between neurons in the nervous system. When a neuron is activated, it releases neurotransmitters into the synaptic cleft, the small gap between neurons. These chemicals then bind to receptors on the postsynaptic neuron, which can lead to the generation of a new action potential in that neuron, depending on the type of neurotransmitter and its receptor.

This process is essential for various functions, including muscle contraction, mood regulation, and response to stimuli. The action of neurotransmitters is foundational to understanding how the nervous system processes information and enables cellular communication throughout the body. Each neurotransmitter can have different effects depending on their types and the receptors they interact with, highlighting their importance in neural signaling.
