Episode notes
INSIGHT

DBS As Circuit-Level Intervention

  • Deep brain stimulation (DBS) targets circuits to treat intractable psychiatric conditions rather than whole-brain symptoms.
  • Chris Rozell frames DBS as an engineered intervention to modulate malfunctioning brain circuits for clinical impact.
INSIGHT

Objective Measures To Support Psychiatry

  • Psychiatry lacks objective biomarkers that clinicians can trust in real time.
  • Rozell stresses that objective brain measures could supplement clinicians' judgment and inform treatment adjustments.
ADVICE

Favor Human-In-The-Loop For Slow Recoveries

  • Use slow, human-in-the-loop adjustments rather than immediate automatic changes when disease recovery is slow.
  • Provide clinicians with decision support tools before attempting fully autonomous closed-loop DBS.
