EEG signal( Description )
•Definition:-An electroencephalogram is a measure of the brain's voltage changes as detected from scalp electrodes.
Electrodes: Small metal discs placed on the scalp in special positions.

EEG signal( Description cont)
•It is an approximation of the cumulative electrical activity of neurons.
•Actions that affect the EEG signals to three categories:-
Muscular Movements Expressive States Cognitive States (Our Scope)

EEG signal( Description cont)
•Study of EEG paves the way for some problem:-
Monitoring Alertness, Coma, and Brain death.
locating areas of damage following head injury and tumour.
Investigating and testing epilepsy.Monitoring the brain development.investigating sleep disorders and mental disorders.

Brain Computer Interface(Description)
Definition:-
Brain Computer Interface (BCI) is a collaboration in which a brain accepts and controls a Mechanical device as a natural part of its representation of the body.

Brain Computer Interface( Description cont. )
What is it good for ?
•People with little muscle control.•Early medical diagnosePeople with Amyotrophic lateral sclerosis(ALS)
Spinal injuries.Mental disorders.
Dementia.(cognitive abilities).Epileptic disease.

Brain Computer Interface( Description cont. )
•In Review
Allow those with poor muscle control to communicate and control physical devices
