Can hallucinogens treat depressive states?

Studies have shown a single dose of psilocybin can offer relief from depression for months at a time, and last year, a clinical trial of 3,4-methylenedioxymethamphetamine, or ecstasy, showed it can alleviate posttraumatic stress disorder. How these hallucinogens exert their effects remains something of a mystery.

How do you explain reuptake?

Reuptake: The reabsorption of a secreted substance by the cell that originally produced and secreted it. The process of reuptake, for example, affects serotonin. Serotonin is a neurotransmitter (a chemical messenger). It is produced by nerve cells in the brain and is used by nerves to communicate with one another.

What is reuptake in a neuron?

n. the process by which neurotransmitter molecules that have been released at a synapse are reabsorbed by the presynaptic neuron that released them. Reuptake is performed by transporter proteins in the presynaptic membrane.

What does drug reuptake mean?

Reuptake means reabsorption. It is a normal mechanism by which the body controls how long a nerve signal lasts. However, if you have significantly low levels of a neurotransmitter, reuptake can be a problem as it restricts the amount of neurotransmitters being actively circulated in the brain.
