Where this comes from

Abstract

Ketamine has been shown to reduce depression and suicidality in individuals resistant to treatment by other drugs. Exactly how ketamine works is not known. Here, I propose a new hypothesis that involves synaptic and circuit plasticity and may lead to enhanced efficacy in treating depression as well as other conditions.
