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
What else can I help you with?
What does Stimulants do Decrease alertness Increase alertness or None of the above?

Drugs that act directly on the brain causing increased activity are?
stimulants are drugs that act directly on the brain causing increased activity.
What is the action of depressants and stimulants on the synapses of the nervous system?
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.
Can neurotransmitter be exogenous?
Yes, exogenous neurotransmitters are chemicals that are taken from outside the body and can affect neurotransmitter activity in the brain. These can include medications like antidepressants and stimulants that alter the levels of neurotransmitters like serotonin, dopamine, and norepinephrine.
What chemicals do amphetamines cause your brain to release?

What are types of stimulants?
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
Does stimulants slow the brain down or speed it up?
Stimulants speed up the brain by increasing the activity of certain chemicals like dopamine and norepinephrine. This can lead to enhanced alertness, focus, and energy levels.
