one path is important for movement. another path is important for memory and cognition.
Most antipsychotic drugs decreases activity at dopamine synapses. L-dopa, used for Parkinson's disease, increases availability of dopamine
Dopamine is commonly referred to when discussing the rewards system of the brain. This neurotransmitter is responsible for acting as the system for the brain. Thus when extra dopamine is released during drug usage, it causes a positive association with the drug to be formed. In short: More dopamine = more drive to recreate the experience
Sugar causes your brain to release dopamine. This is a natural "high" chemical - it causes a feeling of pleasure and satisfaction. This release of dopamine explains why humans have always craved sugar, and why people feel that they are "addicted" to sweets.
Acetylcholine
You mean dopamine. Opiates cause your brain to release your dopamine supply which is what causes the euphoria.
Methamphetamine (METH) increases the amount of dopamine released in synapses. Methamphetamine enters the neuron by passing directly through nerve cell membranes. It is carried to the nerve cell terminals by transporter molecules that normally carry dopamine or norepinephrine. In the nerve terminal, methamphetamine enters the dopamine- or norepinephrine-containing vesicles and causes the release of neurotransmitter. Methamphetamine also blocks the dopamine transporter from pumping dopamine back into the transmitting neuron.
if your asking "how" i believe it lowers dopamine productionUpdate: Kind of. Anti psych medications block dopamine receptors. This causes lower levels of dopamine.
Insufficient levels of dopamine can cause problems with sleep, mood and movement. For example, lack of dopamine causes the muscular problems seen in people with Parkinson's disease.
dopamine is the brain chemical that is released when a person uses marjuana. Dopamine creates good feelings-for a short time.
Well, the reason you're not very angry, or sad when high on weed is because when you smoke it increases the amount of Dopamine let out of the Dopamine Receptors. What is Dopamine? Dopamine is a chemical in your brain, whenever you're in a good mood, dopamine is released from the receptors, weed speeds the amount of dopamine released drastically. Dopamine is responsible for pleasure such as eating and sex. About being resistant to pain, I'm not quite sure and am unable to find anything online, but I'm about 80% positive it has something to do with dopamine.
A lack of dopamine causes Parkinson's disease. As dopamine is an interneuron synaptic neurotransmitter, it controls the passage of impulses along different neurons. If it can't regulate the signal, this leads to frequent involuntary movements as in Parkinson's.
the release of dopamine causes pleasure, reinforcing a behavior.
Dopamine and Serotonin are two neurotransmitters that are important in psychosis
