Acetylcholine- it is widespread throughout the cerebral cortex, hippocampus and brain stem. Norepinephrine- it is located in the brain stem, particularly in the locus coeruleus of the midbrain; limbic system; some areas of the cerebral cortex. Dopamine- located in the substantia nigra of the midbrain; hypothalamus; is the principal neurotransmitter of the extrapyramidal system. Serotonin- Histamine ATP Andenosine GABA Glutamate Glycine Endorphines Tachykinins Somatostatin Nitic Oxide Acetylcholine- it is widespread throughout the cerebral cortex, hippocampus and brain stem.

What is the most common excitatory neurotransmitter in the brain?
Glutamate
What neurotransmitter functions as a common inhibitory neurotransmitter in the brain?
GABA (Gamma-AminoButyric Acid) is the most common neurotransmitter producing inhibition in the brain.
The neurotransmitter most frequently associated with the Reward pathway of the brain is?
s the neurotransmitter most closely linked to learning that certain behaviors are rewarding.
What is the name of enzyme which is used for inactivation of neurotransmitter?
There are a number of neurotransmitter deactivators. For example acetylcholinesterase and anticholinesterases. These are 2 of the most important ones.
Which inhibitory neurotransmitter is considered to be the most prevalent in the mammalian CNS?
GABA, or gamma amino butyric acid, is made from glutamate in the cells of the brain. This inhibitory neurotransmitter blocks nerve impulses.
What are the excitatory neurotranmitters?
Glutamic acid (glutamate) is probably the most abundant excitatory transmitter. Others can be excitatory, such as acetylcholine, and some peptides. Aspartate is also excitatory. Finally, serotonin is often found to be exctitatory.
Is it true that once the effects of a stimulant wear off the driver could quickly fall asleep?
That is true. Most stimulants work by binding to excitatory neurotransmitter receptors (such as the case with amphetamines), inducing the release of excitatory neurotransmitters (such as dopamine and norepinephrine, in the case of amphetamines), preventing the breakdown of excitatory neurotransmitters (as in the case of Ritalin, cocaine, etc.), or blocking inhibitory receptors (as in the case of caffeine). When this happens, the brain adjusts by reducing its sensitivity to its own excitatory neurotransmitters...especially in the case of adrenaline (epinephrine), noradrenaline (norepinephrine), and dopamine. So, once the stimulant wears off, the body is not only fatigued again, but is actually MORE sleepy than before...making it very easy to fall asleep.
The neurotransmitter most likely produced when a person uses a drug that creates a sense of well-being is?
Most likely Dopamine which in excess accumulated in the brain cause schizophrenia.
What drugs are used to treat patients with Lewy body dementia?
most notably a class of drugs called cholinesterase inhibitors . These medications tend to increase a brain neurochemical called acetylcholine, which is an excitatory brain chemical that is decreased in persons with LBD
What is the most significant neurotransmitter in the basal ganglia?
What is the most significant neurotransmitter in the basal ganglia? dopamine
What neurotransmitter is most affected by nicotine and how does tobacco affect the neurotransmitter?
acetylcholine
What are two neurological drugs?
Nicotine is one of the most common drugs that acts on the nervous system. It binds to the same receptors that acetylcholine binds to, creating a similar excitatory effect. This is why nicotine is a stimulant. Nicotine also facilitates the release of dopamine in the brain, giving smokers that relaxed, more alert feeling. Another drug that affects the nervous system is alcohol. In low doses, it acts as a stimulate, partially because it acts on glutamate receptors (glutamate is the most common excitatory neurotransmitter in the brain). However, in high doses, alcohol is a depressant, acting on GABA receptors (GABA is a major inhibitory neurotransmitter). Alcohol causes motor, cognitive, verbal, and perceptual impairments. However, nicotine is one of the most addictive substances in the United States, and both drugs have serious side effects on other areas of the body.
