Science-based meditation

Your Brain has a Focus Signal

Picture this: a meditation practice where you can hear, in real time and from your own brain, exactly when your focus locks in and when your mind starts to drift. After each session, you can see how long you stayed focused and where your attention wandered, so “is this actually working?” finally has an answer.

A vast body of EEG research has shown how specific brain rhythms reflect different mental states. Building on that work – and two decades of EEG experience – Dr. André Keizer identified a robust focus signal: a drop in occipital alpha power when you actively attend to the dark space behind your eyelids, and a rise when your mind wanders.


This free guide walks you through the research behind that signal, the CEVAM method built around it, and the technology that finally puts measurable focus training – grounded in your own brain activity – in your hands.

What you'll learn

01

Why not all meditation is the same

And which of the three scientifically recognized styles actually trains attention

02

The "holy grail" of meditation research

How scientists cracked the difference between a focused mind and a quietly wandering one

03

Occipital alpha power

Why this single neural marker, measured from the back of the head, has become the most reliable real-time signal of attention.

04

CEVAM

The new protocol that takes measurable focus out of the lab and into your daily practice
