mind altering drugs

Saltatory conduction

Faster nerve impulse transmission where ions move only at nodes of Ranvier due to electric fields opening voltage-gated channels at the next node, requiring less ATP.

Drug

Any substance altering body function.

Neonicotinoid pesticides

Block acetylcholine binding to insect acetylcholine receptors, causing paralysis and death without affecting mammals.

Cocaine

Inhibits dopamine reuptake by blocking the dopamine transporter, prolonging dopamine presence in the synaptic cleft for a longer pleasurable sensation.

Alcohol

Acts as an inhibitory neurotransmitter by binding to GABA receptors, making the postsynaptic membrane more negative and reducing the likelihood of an action potential.
