What is an EEG performed to measure?

An EEG, or electroencephalogram, is performed to measure the electrical activity of the brain. It captures the brainwaves as they pop up during various mental states, like when you're relaxed, focused, or even dreaming. This electrical dance of neurons provides crucial insights into brain disorders, seizures, sleep conditions, and helps doctors understand what's going on in that fascinating head of yours! In real-world application, EEGs are used beyond just medical diagnoses. They assist in research related to brain-computer interfaces (BCIs), where signals from the brain are used to control devices, like prosthetic limbs or even gaming systems! Imagine a video game where you control your character merely by thinking about it! EEG technology is transforming how we interact with machines and expanding the boundaries of what we thought was possible.
