Neurons expressing certain types of neurotransmitters sometimes form distinct systems, where activation of the system affects large volumes of the brain, called volume transmission. Major neurotransmitter systems include the noradrenaline (norepinephrine) system, the dopamine system, the serotonin system, and the cholinergic system, among others.
A neurotransmitter is a type of molecule that carries signals between neurons (nerve cells) at synapses in the nervous system The main article for this category is Neurotransmitters . Wikimedia Commons has media related to Neurotransmitters .

Neurotransmitter receptor – membrane receptor that can be activated by a neurotransmitter. Interactions between neurotransmitters and neurotransmitter receptors can evoke a wide range of differing responses from the cell receiving the signal, including excitation, inhibition, and various types of modulation.

Developmental neuroscience aims to describe the cellular basis of brain development and to address the underlying mechanisms. The field draws on both neuroscience and developmental biology to provide insight into the cellular and molecular mechanisms by which complex nervous systems develop. Human brain development timeline
Glutamate is a very major constituent of a wide variety of proteins; consequently it is one of the most abundant amino acids in the human body. [1] Glutamate is formally classified as a non-essential amino acid, because it can be synthesized (in sufficient quantities for health) from α-ketoglutaric acid, which is produced as part of the citric acid cycle by a series of reactions whose ...
The following is a list of neuroactive peptides co-released with other neurotransmitters. Transmitter names are shown in bold. Norepinephrine (noradrenaline). In neurons of the A2 cell group in the nucleus of the solitary tract), norepinephrine co-exists with: Galanin; Enkephalin; Neuropeptide Y; GABA. Somatostatin (in the hippocampus ...
Neurotransmission is regulated by several different factors: the availability and rate-of-synthesis of the neurotransmitter, the release of that neurotransmitter, the baseline activity of the postsynaptic cell, the number of available postsynaptic receptors for the neurotransmitter to bind to, and the subsequent removal or deactivation of the ...
