In this paper, investigate the use of brain activity for person identification. A biometric system is a technological system that uses information about a person. Research on brain signals show that each individual has a unique brain wave pattern. Electroencephalography signals generated by mental tasks are acquired to extract the distinctive brain signature of an individual. Electroencephalogr...

Several recent articles re-emphasize the value of clinical electrophysiology: in localizing epileptogenesis, predicting effectiveness of epilepsy surgery, and disclosing a mechanism of benign Rolandic epilepsy of childhood.A review of the role of EEG in the diagnosis of epilepsy indicated that epileptiform activity will appear in 50% of initial awake recordings of adults with epilepsy and in 85...

Electroencephalography (EEG) is a noninvasive, widely available, and relatively inexpensive test that can help exclude or identify structural or functional factors contributing to psychiatric syndromes. This article defines the clinical usefulness of EEG in evaluating neuropsychiatric disorders, emphasizing the complementary nature of the visually inspected standard EEG (SEEG) and the computera...

The main focus of the self-stimulation phenomenon, as indicated by maximum rates for minimum stimulus levels and by lesion studies, iies in an olfactory midbrain pathway through septal area, lateral hypothalamus and ventrolateral tegmemum; over most of its course this pathway is called the medial forebrair bundle. The studies which indicated this "focus" also showed a gradient of self-stimulati...

EEGs are commonly requested by physicians in medical wards for patients with altered conscious levels and also in the outpatient setting for investigation of seizures. This article seeks to explain how EEG is performed and explore the correct indications for its use.

Some children with severe retrolental fibroplasia have mental retardation. It is difficult to determine whether this retarda­ tion is based only on the loss of vision or whether it is related to cerebral damage. With the hope that electroencephalography would give some evidence that would help to separate these factors, a series of children with severe retrolental fibroplasia in cicatricial sta...
