do barbiturates stimulate the central nervous system
No. Depressants are the opposite of stimulants. Stimulants are drugs that stimulate the brain and central nervous system, speeding up communication between the two. Depressants slow down the activity of the brain and nervous system, slowing down the communication between the two.
Stimulants are also known as "uppers" or psychostimulants. It enhances the activity of central and peripheral nervous systems.
The central nervous system
Central nervous system stimulants are used to keep patients who suffer from narcolepsy from falling asleep. Narcolepsy is a disorder that causes people to fall asleep during daytime hours.
Amphetamines are stimulants of the central nervous system and sympathetic division of the peripheral nervous system.
The combination of amantadine and central nervous system stimulants (e.g., amphetamines or decongestants) may cause increased central nervous stimulation or increase the likelihood of seizures.
Stimulants and depressants have opposite effects on the brain. Stimulants activate the central nervous system, while depressants (as their name implies) depress it.
