Central nervous system (CNS) stimulants are drugs that increase activity in certain areas of the brain. These drugs are used to improve wakefulness in patients that have narcolepsy.
No, drugs can have vastly different effects on the central nervous system.
A. Burger has written: 'Drugs affecting the peripheral nervous system' 'Drugs affecting the central nervous system'
Drugs slower the nervous system.
Many drugs will actually improve the human nervous system with almost no side effects. One of the most effective drugs that anybody could take to improve their nervous system is heroin
These drugs depress the central nervous system and should not be taken with other drugs, such as alcohol, barbiturates, antihistamines, and benzodiazepines that also depress the central nervous system.
Excitatory psychoactive drugs such as nicotine and cocaine primarily affect the central nervous system. They increase post-synaptic transmissions and may result in addictions and substance abuse. These stimulants increase the alertness of the user by mimicking the action of neurotransmitters or delaying the breakdown of neurotransmitters. They can also affect the transmission of optical signals in the thalamus of the brain.
