Hi there, it's Matt here and welcome back to the podcast. Today we're venturing into an exciting

realm of human health that goes far beyond sleep into general topics of the brain. And I'm trying

this because many listeners have asked me to cover more brain science topics

on the podcast. And since I absolutely love all things brain, not just sleep, I wanted to broaden

the podcast to reflect that and show just how utterly incredible the human brain is.

Today, we're going to be diving into the real science of something

called 40 Hertz stimulation therapy. In this episode, we'll dive deep into what happens when you

expose the human brain to a very specific rhythm, 40 cycles per second, known as the gamma frequency. We'll talk about how flickering

lights and pulsing sounds at 40 hertz might enhance cognition and memory, potentially fight

Alzheimer's disease, improve sleep quality, regulate mood, and even influence energy levels.

And as always, we'll stay grounded in the science, focusing only on peer-reviewed research,

especially human studies.

I'll try to spare you the social media hype and the marketing, and just focus on the

scientific data. Before we dive in, let's set the

stage. 40 Hertz refers to a frequency of 40 cycles per second. When your neurons synchronize at this

rhythm, it's like they're all humming together at 40 beats per second. If that sounds fast, it is.

Imagine a hummingbird flapping its wings, which happens about 40 to 50 times per second.

That's the kind of rapid beat we're dealing with, but in electrical bursts of neural activity.

Why 40 hertz? Gamma waves in the brain have long been linked to higher order cognitive functions. When you concentrate hard, solve a problem,

or try to recall a memory. Studies show an increase in gamma activity as different brain regions

communicate in synchrony. Think of gamma as the conductor of an orchestra, ensuring multiple brain

areas stay in tempo during mentally demanding tasks. Scientists began wondering, could boosting gamma rhythms at 40
