The Question: How do drugs affect our brain and actions? Or the mind-body
phenomenon. Must use atleast 5 of the terms listed below.
This is for a Bilogical Psychology class.
Central Nervous System: The brain and spinal cord.
Cerebral cortex: The region of the brain responsible for cognitive
functions including reasoning, mood, and perception of stimuli.
Dissociative: a type of compound, such as phencyclidine or ketamine,
that produces an anesthetic effect characterized by a feeling of being
detached from the physical self.
Flashback: A sudden but temporary recurrence of aspects of a drug
experience (including sights, sounds, and feelings) that may occur days,
weeks, or even more than a year after hallucinogenic drug use.
Glutamate: An excitatory neurotransmitter found throughout the brain
that influences the reward system and is involved in learning and
memory, among other functions.
Hallucinogen: A drug that produces hallucinations—distortions in
perception of sights and sounds—and disturbances in emotion,
judgment, and memory.
HPPD: Hallucinogen persisting perception disorder; the spontaneous
and sometimes continuous recurrence of perceptual effects of LSD long
after an individual has ingested the drug.
Kappa opioid receptor: A receptor on nerve cells that is activated by
certain opioid-like compounds produced in the body. These receptors
differ from those activated by the more commonly known opioids, such
as heroin and morphine.
Neurotransmitter: A chemical compound that acts as a messenger to
carry signals from one nerve cell to another.
NMDA receptors: N-methyl-D-aspartate receptors, a type of glutamate
receptor that is important for learning and memory; it is the target of
drugs such as PCP and ketamine.
Persistent psychosis: Unpredictable and long-lasting visual
disturbances, dramatic mood swings, and hallucinations experienced
by some LSD users after they have discontinued use of the drug.
Serotonin: A neurotransmitter involved in a broad range of effects on
perception, movement, and emotions. Serotonin and its receptors are
the targets of most hallucinogens.
