What is EEG?

Electroencephalography (EEG) is a high-speed non-invasive neuro-sensing technique that records microvolt-level electrical voltages generated by millions of firing brain cells at millisecond speed.

The Brain's Electrical Telegraph

Listening to Microvolt Neuronal Waves

Every thought, emotion, and focus state is driven by 86 billion neurons firing synchronized electrical impulses (post-synaptic potentials) inside your cerebral cortex.

These tiny ionic currents travel through tissue and scalp, producing microvolt fluctuations (10μV to 50μV)—about 100,000 times weaker than a AA battery!

The 5 Brainwave Rhythms

Running real-time Fast Fourier Transform (FFT) on raw EEG microvolt data.

Delta (δ) 0.5 – 4 Hz

Deep Sleep & Recovery: Dominant during deep, dreamless sleep. Essential for brain cell repair and memory consolidation.

Theta (θ) 4 – 8 Hz

Meditation & Screen Fatigue: Associated with deep meditation, creative intuition, or growing mental drowsiness during long iPad screen sessions.

Alpha (α) 8 – 12 Hz

Calm Flow State: The signature of relaxed focus, calm alertness, and effortless learning ("In the Flow Zone").

Beta (β) 13 – 30 Hz

Active Work & Problem Solving: Surges during intense analytical thinking, executive decision-making, and active coding/work.

Gamma (γ) 30 – 100 Hz

Peak Cognitive Synthesis: High-frequency processing during rapid memory recall, complex problem resolution, and peak athletic execution.

Texas Instruments ADS1292R AFE

Powered by a 24-bit 2-channel biopotential ADC with an integrated 12x Programmable Gain Amplifier (PGA) to resolve microvolts with zero distortion.

Clinical Neuro-Technology

Medical Applications & Seizure Monitoring

From hospital neurology clinics to 24/7 continuous wearable monitoring.

Clinical Standard

Epilepsy & Seizure Diagnostics

In hospital neurology, EEG is the global gold standard for diagnosing Epilepsy, detecting subclinical absence seizures, and mapping abnormal cortical spike-and-wave discharges.

Abnormal neuronal hypersynchrony produces distinctive 3Hz generalized spike-and-wave electrical bursts that are instantly identifiable on prefrontal EEG channels.
