Adrenaline (epinephrine) and noradrenaline (norepinephrine) are sympathetic neurotransmitters that:
- increase excitatory neurotransmission in the central and autonomic nervous systems
- induce vasoconstriction (increasing blood pressure, shunting blood away from the surface of tissues, etc.)
- induce glycolysis through a cascade mechanism, whereby glycogen is quickly broken down into glucose in cells, increasing blood sugar levels to aid increased glucose metabolism in the brain and other organs
Stimulants effect the brain in many ways! Most of the time they increase levels of Dopamine and Norepinephrine in the Brian. These chemicals often are abused due to Dopamine increasing the pleasure responses in the Brain and Norepinephrine for its effects on mood. That is why people do cocaine or take prescriptions like Adderall or Ritalin to achieve hit higher than normal pleasure signals in the brain. Just a statistic, a line of cocaine insufflated increases dopamine levels by 150% instantly, and is why it is abused! Most people who are drug addicts that use illegal stimulants actually have ADD/ADHD and are using these drugs to combat the disorder and not even know it! They are very addictive and can have bad side effects and withdrawal symptoms!!! Some side effects from stimulants are nervousness, irritability, seizers, coma, or death!!! Withdrawal symptoms are all the same but without the death part. LOL!!! Getting tired! Time for a cup of coffee!!! LOL... Remember Caffeine does the same thing!!!
The pre-frontal visual cortex.
stimulants are drugs that act directly on the brain causing increased activity.
Generally, depressants slow down neurotransmission (messages sent from neuron to neuron) reducing overall activity in the brain, whereas stimulants speed up the amount of neurotransmission, hence increasing overall activity in the brain.
Amphetamine is 1-phenylpropan-2-amine. Amphetamines are drugs that increase levels of the neurotransmitters norepinephrine, serotonin, and dopamine in the brain. They are commonly used as stimulants and appetite suppressants.
Yes, a brain tumor is very serious affect. It can kill you. Most people that develop a brain tumor can die shortly afterwards.
Stimulants come from, the folks who make them.
Stimulants and depressants have opposite effects on the brain. Stimulants activate the central nervous system, while depressants (as their name implies) depress it.
they affect the nervous system.
Vicodin has the potential to alter the brain's neurotransmitters.
stimulants increase activity and depressants decrease activity.
Yes it does
stimulants speed up messages along the brain there's legal stimulants caffeine found in cola drinks coffee and tea and, illegal stimulants like cocaine,ecstasy and amphetamines
the answer is Stimulants.... XD
stimulants
yes it stimulants the brain it and and everything in your body speed up.
stimulants are drugs that act directly on the brain causing increased activity.
The chemical compounds in Stimulants, Nicotine, Opioids, alcohol, and Sedatives enter the brain and bloodstream upon use. Once a chemical enters the brain, it can cause people to lose control of their impulses or crave a harmful substance.
How does a brain tumor affect the Brain?
