How much should we know on how a human brain works? 
This is a tricky question. Instead of getting lost in endless discussions, let’s dive into how wearable technology can make a difference in aggregating real life data about the activity of the brain.
How is brain activity measured?
Electrical Brain activity is accumuluated via EEG – meaning Electroencephalography 
yeah, what a tongue twister! In the essence one can measure electrical activity generated by the synchronized activity of thousands of neurons in volts. Because these signals are transmitted with near to no latency, EEG provides excellent time resolution.
By applying multiple electrodes distributed over the skull, a 3D image of the brain activity can be computed. See illustration 1-5 in the below image to get from raw data aggregation with electrodes to mapping the activities to certain regions in the brain.
This makes EEG one of the fastest and smallest imaging techniques available!

What is the potential of a wearable EEG?
Measureing brain activity in the lab is cool, but measuring EEG continuously in real life is what provides the far more valuable insights. As wearable device experts, Leitwert is proud to support companies and researchers in designing EEG-Wearable device that are used for sleep analysis and other purposes.
Besides Sleep Analysis and brain research applications, there are lots of medical applications, where EEG can be used. These include:
Epilepsy (most common)
Dementia
Brain tumor
Brain damage from head injury
Brain dysfunction that can have a variety of causes (encephalopathy)
Inflammation of the brain (encephalitis)
Stroke
Sleep disorders
