The other, Belviq, works on brain receptors for serotonin, a neurotransmitter than triggers feelings of satisfaction.
Another approach to cognitive enhancement, says Dr Robbins, is through a neurotransmitter called acetylcholine.
This chemical is a neurotransmitter: its molecules carry messages from one nerve cell to another.
The target: a neurotransmitter called glutamate and its receptors, which malfunction in the forebrain of psychotic patients.
The drugs affect a neurotransmitter in the brain called acetylcholine and can cause dizziness, drowsiness, confusion, and memory loss.

This substance is a neurotransmitter one of several dozen chemical messengers that carry signals from one nerve cell to another.

Acetylcholine is a neurotransmitter in the brain, meaning it is a chemical used to send messages from nerve to nerve.

Wang has already demonstrated that the mere sight and smell of food can cause a release of dopamine, a neurotransmitter associated with motivation and pleasure.
In one application of optogenetics, scientists investigated how neurons that make dopamine, a neurotransmitter in the brain, may give rise to feelings of reward and pleasure.
Scientists believe glutamate is a much more direct target for depression than serotonin, a neurotransmitter affected by selective serotonin reuptake inhibitor (SSRI) drugs like Prozac and Paxil.
The urge to drink or take drugs is, neurochemically speaking, linked to endorphins (natural morphine-like molecules) or dopamine, a neurotransmitter that is involved in bits of the brain that control reward behaviour.
DRD4 encodes a receptor molecule for a neurotransmitter called dopamine. (Neurotransmitters are chemicals that carry signals from one nerve cell to another.) Those with a variant of DRD4 called 7R, and also a large network of friends acquired during their adolescence, tended to be (in the American sense of the word) liberals ie, left wing.
Sapra and Zak began by analyzing the genes of 60 professional traders working in five major Wall Street firms. (They collected the DNA samples in 2008 only three of the firms are still in business.) The scientists focused on a short list of genes that are known to affect the activity of dopamine, a neurotransmitter in the brain.

It works similarly to many pesticides, by blocking the breakdown of acetylcholine, a major neurotransmitter, leading to a rapid buildup of this chemical in the body.
FORBES: Sarin Gas Is Deadly, But Fear Is More Powerful And More Deadly
One of the main ways schizophrenia drugs differ is in how they inhibit a brain receptor for dopamine, a key neurotransmitter that is overactive in some parts of a schizophrenic's brain.
Nicotine actually exerts its effect by mimicking a second neurotransmitter called acetylcholine.
ECONOMIST: Great drug, shame about the delivery system | The
This receptor, the D2, has a counterpart, the D2 neurotransmitter, and the pairs are scattered in different command centers of the brain.
Dr. James Stone, who authored the research, says that the signaling between these two types of neurotransmitter is happening between a part of the brain called the hippocampus and another called the striatum.

Whether the emotion is anger, euphoria or fear, it triggers neurotransmitter changes that kick the brain into a hyper-alert state.

Blocking substance P triggers a molecular chain reaction that boosts levels of the neurotransmitter serotonin, apparently much more selectively than Prozac does.
CGRP, which stands for calcitonin gene-related peptide neurotransmitter, has long been thought to play a role in migraines, but for much of that time for the wrong reason.
