How EEGs measure brain activity

Chronic stress, cognitive overload, and neurodegenerative disease are rising as modern life pushes the brain beyond what it was designed to handle. At the same time, most people still have almost no visibility into how their brain is actually performing day to day.

In this episode of Extend, we sit down with Ramses Alcaide, founder and CEO of Neurable, to unpack how brain computer interface technology is moving from research laboratories into everyday wearable devices. We break down how non-invasive EEG sensors built into headphones can track brain age, cognitive speed, mental recovery, focus, and stress, and how AI is making brain data accessible without the complex lab equipment historically required.

We also explore how continuous brain monitoring could transform prevention by identifying early patterns linked to burnout, ADHD, traumatic brain injury, and neurodegeneration years before symptoms appear.

Ramses Alcaide is the founder and CEO of Neurable, a neurotechnology company developing non-invasive brain computer interfaces built into everyday wearable devices. He earned a PhD in Electrical Engineering and Neuroscience from the University of Michigan, where his research on EEG biomarkers and brain computer interfaces laid the scientific foundation for Neurable's technology.
