Summary: New research demonstrates the effectiveness of ketamine to treat depression in a mouse model of the disease. The brings together two hypotheses: 1) that depression results from deficits in GABA signaling and 2) that depression results from deficits in glutamate signaling. It shows that the depression-like behavior in the research mice results from the reduction of both GABA and glutamate, and importantly, that both can be restored with a single dose of ketamine.
