Quick answer
What does the neuroplasticity research show?
Animal and human studies suggest sub-anesthetic ketamine triggers rapid synaptic protein synthesis, dendritic spine growth, and BDNF release in the hours after dosing — opening a transient plasticity window that may explain rapid antidepressant effects.

Key findings

  • Rapid mTOR activation and synaptic protein synthesis within 1–2 hours.
  • Dendritic spine restoration in prefrontal cortex within 24 hours.
  • BDNF surge mediating downstream plasticity.
  • Plasticity window appearing to last hours to days, not weeks.

Why integration matters

If the plasticity window is transient, what you do during it shapes what consolidates. This is a major argument for integration practices.
