The latest method of investigating brain function and dense array EEG

Abstract

EEG (electroencephalography) has been used in both clinical for diagnosing neurological diseases and medical technology for developing a Brain machine interface since Dr. Hans Berger first reported human EEG in 1929.<br>EEG is a non-invasive method of investigating brain function with excellent time resolution (msec order), however its used has been limited in clinical because of insufficient spatial resolution. Dense array EEG which has over 100 electrodes and is easy attachment appeared at the beginning of 2000's. Dense array EEG enables us to capture the brain activities with both high time and spatial resolution.<br>In this session, I introduce dense array EEG and show some clinical cases with epilepsy. Also we have discussion for further application possibility of EEG and NIRS as non- invasive method of investigating bran function.
