What Happens Next in 6 Minutes A Breakthrough in Restoring Memory
4 snips
Jul 18, 2026 Michael Kahana, cognitive neuroscientist and founder of Nia Therapeutics, explains his journey from physics to building implantable devices to boost memory. He discusses AI forecasting of memory states, state‑dependent brain stimulation, how brief pulses can reset memory, safety and implantation procedures, and the path from research to human trials and clinical devices.

Episode notes
Memory Fluctuates Dramatically Within Individuals
- Memory performance varies hugely within individuals across days and moments.
- Kahana found within-person variation can be twofold between bottom and top halves, prompting predictive models to forecast good or bad memory states.
AI Can Forecast Your Memory State
- Neural recordings plus AI can forecast when a person's memory will be good or bad.
- Kahana's team built forecasting models from intracranial signals collected across hundreds of patients to predict memory state before stimulation.
Stimulation Helps Only When Timed To Bad States
- Timing of stimulation matters: delivering pulses during good states can worsen memory while targeting bad states can improve it.
- The team learned this by aligning stimulation timing to AI forecasts and observing opposite effects based on state.
