Quick answer
Why this study matters
One of the most-cited mechanistic studies linking ketamine's behavioral effects to specific cellular processes in the prefrontal cortex.
Population
Rodent models
Intervention
Ketamine administration
Comparator
Vehicle, mTOR inhibitors
Primary outcome
Synaptic protein expression, dendritic spine density, behavior

Key findings

  • Ketamine rapidly increases synaptic proteins in prefrontal cortex
  • Effect requires mTOR signaling
  • Provides cellular framework for rapid antidepressant action

Limitations

  • Rodent model
  • Acute, not chronic, observation
