Portable devices for monitoring brain activity

Philip Low created an algorithm that can classify sleep stages using data
from just a single EEG lead. In 2007 he founded NeuroVigil, a startup based
in La Jolla, CA, that manufactures a sleep-monitoring device based on the
technology. 

NeuroVigil's iBrain records EEG data and transmits it to the company by
phone. The iBrain device is small enough to be worn on the head. A cell phone
can relay EEG data to NeuroVigil for analysis. This prototype uses
off-the-shelf Bluetooth transmitters to send data to a cell phone. 

NeuroVigil has used clinical trials to amass a database of readings from
patients with particular diseases. Low hopes that by mining this database, he
will discover EEG signatures in the data that might warn of conditions like
Alzheimer's, schizophrenia, or Parkinson's before symptoms appear.
