Technology Tools

Evidence-based reviews of neurotechnology and cognitive tools. What works, what doesn't, and what the research actually shows.

EEG Headbands (e.g. Muse)

Consumer EEG headbands that turn your brain activity into live feedback for meditation and attention.

How TMS uses focused magnetic fields to treat depression and OCD — the science, FDA-cleared protocols, and what to expect from clinical sessions.

What the research actually shows about tDCS for focus and learning — mechanism, consumer devices, and why the hype outpaces the evidence.

Non-invasive vagus nerve stimulation for anxiety and stress — how it works, which devices exist, and what the clinical evidence supports.

Red and near-infrared light therapy for energy and recovery — the photobiomodulation mechanism, dosing parameters, and where the evidence stands.

Clinical neurofeedback vs consumer apps — what the evidence shows for ADHD and anxiety, how protocols work, and realistic timelines.

How Apollo Neuro and haptic wearables use gentle vibration to calm the nervous system — the science, the trials, and honest limitations.

HRV biofeedback for stress resilience — resonance frequency breathing, the baroreflex mechanism, devices, and the strong meta-analytic evidence.

How Brain.fm and functional audio use neural entrainment for focus and sleep — the mechanism, the research, and how it differs from lo-fi playlists.

The most contested cognitive training tool — what dual n-back actually trains, the transfer debate, and who it might genuinely help.

How tinnitus apps use sound therapy and habituation to reduce the brain's fixation on ringing — the Jastreboff model, specific apps, and evidence.
