Synaptogenesis: How New Connections Form
The cellular process of forming new synapses — and why rapid antidepressants are thought to work by triggering it.
What it is
Synaptogenesis is the formation of new synaptic connections between neurons. It is most active during development and learning, and remains possible across the lifespan, especially in regions like the hippocampus and prefrontal cortex.
Why it matters in mood
Depression and chronic stress are associated with synaptic loss, particularly in prefrontal regions involved in emotional regulation. Restoring synapses may be a final common pathway for many rapid-acting antidepressants.
Ketamine context
Preclinical research suggests ketamine triggers rapid synaptogenesis within 24 hours via BDNF and mTOR signaling. Integration practices may help stabilize new connections.
