JB from NextSense discusses innovative ear EEG technology for sleep monitoring and enhancement.
In this episode of the Neural Implant Podcast, JB , founder and CEO of NextSense , discusses how his team is transforming ordinary-looking earbuds into wearable brain interfaces capable of recording EEG directly from the ear. Originally incubated inside Google X before spinning out as an independent company, NextSense combines consumer electronics with neuroscience to monitor sleep, enhance slow-wave activity through closed-loop audio stimulation, and explore future applications ranging from epilepsy forecasting to Alzheimer's disease monitoring. We also discuss the engineering challenges of ear EEG, wearable neuromodulation, vagus nerve stimulation, and what it takes to bring a neurotechnology product from the lab into consumers' hands. Top 5 Takeaways 1. Ear EEG makes continuous brain monitoring practical Rather than using traditional scalp electrodes, NextSense records EEG directly from the ear canal. While ear EEG doesn't provide the spatial resolution of clinical EEG systems, it offers a comfortable, easy-to-use solution for long-term brain monitoring that users can wear every night like standard wireless earbuds. 2. Closed-loop audio stimulation can enhance deep sleep The…
