10 New Biohacks for Peak Aging: Neurofeedback & Chill Summary
Dr. Andrew Hill explored emerging research on aging interventions in this week's livestream, demonstrating SMR neurofeedback training while covering ten recent findings that could reshape how we approach cognitive longevity. The session combined practical neurofeedback education with cutting-edge aging science, though the transcript cuts off before covering all ten promised biohacks.

Live Neurofeedback Demonstration
Dr. Hill set up a dual-protocol session using the Eager software:
Protocol 1: C4-A2 SMR Training (12 minutes)
- Target: 12-14.75 Hz sensory motor rhythm
- Inhibit: 4-7 Hz theta
- Purpose: Executive function, sleep quality, impulse control
Protocol 2: Pz-A1 Alpha Training (12 minutes)
- Target: 7-10 Hz "idling alpha"
- Purpose: Reduce rumination, threat sensitivity, speed processing
This combination targets both frontal executive control and posterior cingulate regulation—circuits directly relevant to healthy aging.
Aging Research Context
The session began exploring how recent findings challenge traditional aging assumptions. Dr. Hill emphasized that several discoveries deserve dedicated deep-dives, asking viewers to indicate which topics warrant full treatment.
Two key themes emerged before the transcript ended:
- Speed of processing improvements through specific interventions
- Stress response modifications that may slow cognitive decline
The posterior cingulate protocol (Pz-A1) directly addresses both areas, as this region regulates rumination and threat detection while supporting cognitive speed.
Notable Q&A Insights
Question: Is referencing to an ear (A1) roughly equivalent to referencing to the mastoid bone for SMR training?
Answer: They're similar but not identical. For training purposes, A1 and M1 (mastoid) produce comparable signals when using locations like C4 or Cz as the active electrode. However, you can't substitute mastoids for earlobes in QEEG assessment—databases are built with specific reference schemes.
For home training, if you can't access earlobes easily, you can paste a flat wire directly onto the earlobe with tape rather than switching to mastoids.
Key Mechanisms Explained
SMR's Anti-ADHD Properties: SMR represents the neurophysiological opposite of ADHD patterns. Strong SMR enables cats to hold perfectly still while stalking prey—combining deep relaxation with focused attention. This same thalamocortical rhythm strengthens sleep spindles and reduces physical fidgetiness.
Sleep-ADHD Connection: Research from Martin Arns (Netherlands) suggests ADHD may partially reflect sleep regulation dysfunction. People with ADHD often show altered sleep architecture and compromised sleep spindles—the same 12-14 Hz rhythm trained as SMR during waking states.
Alpha Frequency and Aging: The Pz-A1 protocol targets "idling alpha" (7-10 Hz), which naturally slows with age. Training this frequency can restore cognitive speed while dampening the posterior cingulate's role in rumination and self-referential thinking.
Practical Takeaways
- Home neurofeedback is accessible: Clean signals matter more than millimeter-perfect electrode placement (~1cm tolerance)
- Dual protocols address aging: Combining frontal SMR with posterior alpha targets multiple aging-related circuits
- Sleep and focus interlink: Training the same thalamocortical circuits improves both daytime attention and nighttime sleep quality
- Traditional approaches work: Single-channel protocols often outperform complex multi-channel systems for precise training
The livestream format allows real-time demonstration of these principles while exploring cutting-edge research—though the complete list of ten aging biohacks remains to be revealed in future sessions.
