Faster brainwaves are associated with active thinking and alertness, while slower waves occur during states of relaxation, creativity, or sleep. Each type of brainwave serves a specific purpose, and maintaining a healthy balance between them is crucial for optimal mental health and performance.
Brain waves are patterns of electrical activity occurring in the brain. They are categorized based on their frequency (measured in Hertz, Hz), which represents the number of cycles per second. Each type of brain wave is linked to specific states of consciousness, alertness, and behavior.
MIT neuroscientists have found that the six anatomical layers of the mammalian brain cortex show distinct patterns of electrical activity which are consistent throughout the entire cortex and across several animal species, including humans.
Like musical sounds, different states of mind are defined by distinct, characteristic waveforms, recognizable frequencies and rhythms in the electrical field of the brain.
At the root of all our thoughts, emotions and behaviours is the communication between neurons within our brains. Brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. This activity is detected using sensors placed on the scalp.
Brainwaves are electrical readings that reflect brain activity. These electrical impulses can vary in speed and are measured in cycles per second, or hertz (Hz). You can detect a person’s mental state and measure the electrical activity in specific brain areas related to a particular brain function while looking at the brainwave activity.
Brainwaves are patterns of electrical activity in the brain, each occurring at different frequencies: delta, theta, alpha, beta, and gamma. Frequency refers to how fast a brainwave oscillates. For example, alpha waves cycle 8 to 12 times per second, or 8–12 Hz.
Let’s break down the four primary types of brainwaves—Alpha, Beta, Theta, and Delta—and explain what they mean for your mind and body. Alpha waves are typically produced when you’re in a relaxed yet alert state.
Here, we present BrainWave, the first foundation model for both invasive and non-invasive neural recordings, pretrained on more than 40,000 hours of electrical brain recordings (13.79 TB of data) from approximately 16,000 individuals.
Here, we introduce for the first time newly developed open-source software and instructions for building, testing, debugging, and using BrainWAVE (Brain Wide-spectrum Audio/Visual Exposure) stimulation. We demonstrate BrainWAVE stimulation across multiple species and different experimental settings.
