Psychoactive Drugs Flashcards
What are psychoactive drugs?
Psychoactive drugs are chemicals that cross the blood brain barrier and alter brain chemistry and functioning. Lead to changes in perception, cognition, volition, mood or behaviour.
Picture a psychoactive (Norman Bates in tie die) runner running through the blood brain barrier with chemical symbols in their hands. When they get through they drop the chemicals and start rearranging beakers.
What is the blood-brain barrier?
is the barrier between the circulating blood and the extra-cellular fluid in the brain.

Is the re-absorption of neurotransmitters by receptors in the presynaptic membrane.
Picture nero with his router being sucked through a membrane with the picture of an arrow in front of a deviled egg with a tic.

What is a receptor?
An organ or cell able to respond to light, heat, or other external stimulus and transmit a signal to a sensory nerve.
A region of tissue, or a molecule in a cell membrane, that responds specifically to a particular neurotransmitter, hormone, antigen, or other substance.
Picture an organ with a ray of light on it, a flame to it etc. When this happens the organ speaks to a nerve to transmit the sensation it is receiving.
Picture a tissue speaking to Nero with his router. It takes in what Nero is saying and writes a letter back to him (responds)
What is an antagonist?
Chemical that binds to a receptor but has no action. Prevents other substances for binging, effectively turning off the receptor.
Picture Aunt Agonist is sitting on your porch when you want to have a party. The house looks so lame that no one wants to come into the house for the party.
