Abstract
The neurons of the human brain generate electrical activities related to
body functions. The generated potential distribution can be measured
with elctrodes placed on the scalp (electroencephalography, EEG). EEG
signals can be related to sponteneous, event related or evoked potential
recordings. The EEG pattern change in stiuations of alertness, resting
or sleep. It is possible to communicate with the environment and control
a computer or another device, by using mu and P300 waves. These systemss
are called brain computer interfaces or interactions, and widely used.
Oxygenation in the brain can be observed with functional near-inrared
spectroscopy (fNIRS). By using these systems, brain functions of people
whose work require attention, can be monitored. In this study, EEG and
fNIRS are proposed for some military purpose. A person whose task
requires high alertness can be monitored using their brain functions.
Observance of a person by a command center in some critical tasks such
as the jet piloting where it is required to give rapid and correct
decisions under stress or under the risk of loss of conscious, or the
surveillance of critical areas or devices would highly support the
performance of the mission. Inaddition, it is possible to use EEG
signals to make easier the lives of veterans who have normal brain
functions but suffer from physical or speech disabilities or in the
investigation of their brain trauma.... Show more Show less
