Tools for reading brainwaves have been around since 1912, when Russian physiologist, Vladimir Vladimirovich Pravdich-Neminsky published the first use of electroencephalography (EEG). However, this technology was way ahead of its time. The first digital computers weren’t created until the 1940’s! As a result, the first EEG recordings were difficult to understand, compare, and make relevant. Now, one hundred years later, we live in an age where technology is rapidly getting cheaper, smaller, and more portable. As a result, wearable technology has emerged as an exciting field with seemingly limitless possibilities to record all aspects of life in real-world environments. We think this trend equates to some pretty exciting possibilities for taking EEG outside of the laboratory!
Now, you might be asking yourself what EEG actually means. If you haven’t googled it already, EEG is all about measuring the teeny-tiny electrical signals that our brains make when we do things. These signals are emitted when we think, day-dream, sleep, move around, or meditate – pretty much all the time, if you think about it. Whenever we use our brains, electrical impulses are moving and potentials are flowing all around inside of our heads. EEG is a technique for recording these brain signals.
An EEG system has three basic parts to measure these signals: electrodes which are placed on the scalp; an electronic amplifier that can sense and relay the tiny electrical changes that your brain makes; and a signal processing computer used to make sense of the data and map it to some type of output. After that, the possibilities are endless! One of the most important links in the chain is the amplifier. It is the goal of our Kickstarter to make an open-source, affordable, high-quality EEG amplifier available to everyone so that those possibilities we are talking about can be realized by anyone.
