Neurotransmitters evoke postsynaptic electrical responses by binding to members of a diverse group of proteins called neurotransmitter receptors. The receptors then give rise to electrical signals by opening or closing ion channels in the postsynaptic membrane.

Neurotransmitters play a role in nearly every function in your body. More specifically, neurotransmitters are the chemical communicators that carry a nerve’s message from one nerve cell to the next cell. Without neurotransmitters, your body can’t function.

Neurotransmitter receptors transmit the actions of bound neurotransmitters, thus enabling cell-to-cell communication in the nervous system. Most receptors are integral membrane proteins categorized as ligand-gated ion channels or G protein-coupled receptors (GPCRs).

2022年10月27日 · Neurotransmitter receptors are heterogeneously distributed across the neocortex and respond to the binding of a neurotransmitter. By modulating the excitability and firing...

2023年5月1日 · Neurotransmitters are endogenous chemicals that allow neurons to communicate with each other throughout the body. They enable the brain to provide a variety of functions, through the process of chemical synaptic transmission.

2023年9月27日 · Neurotransmitters are chemical messengers that facilitate communication between nerve cells, or neurons. These messengers travel across a tiny gap called a synapse, enabling signals to pass from one neuron to the next. Unlike direct contact, neurotransmitters bridge this synaptic gap to relay signals to or from the central nervous system (CNS).

Neurotransmitters are molecules that amplify, transmit, and convert signals in cells, having an essential role in information transmission throughout the nervous system. Hundreds of such chemicals have been discovered in the last century, continuing to be identified and studied concerning their action on brain health.

A neurotransmitter receptor is defined as a protein localized in various membrane compartments within the central nervous system, playing a crucial role in receptor-mediated pathways and neurotransmission. You might find these chapters and articles relevant to this topic.

Neurotransmitters are signaling molecules that generate an excitatory or inhibitory response on the postsynaptic membrane, thereby propagating or preventing an action potential. Neurotransmitters can be categorized as small molecules or neuropeptides.

Neurotransmitters each bind to specific receptors that produce specific postsynaptic responses. The subsequent chapters will review the main neurotransmitters including their synthesis, storage, and their receptors.
