INTRODUCTION: Like other cells, nerve cells also show changes of electrical potential during activity which can be detected, amplified and recorded in the form of waves with an instrument called electroencephalograph
. The EEG waves are due to current flow in the fluctuating dipoles formed on the dendrites of the cortical cells and cell bodies.
Briefly, under pentobarbital (50 mg/kg, i.p.)-induced anesthesia, two stainless steel screws attached to insulated wire were implanted in the skull over the frontal-parietal cortex for electroencephalographs
Scientists at New York University School of Medicine used a computer to analyze brain waves from electroencephalographs
(EEGs) conducted among 44 healthy people, aged 64-79, who were taking part in a long-term study of dementia.
to monitor brain activity, Posner put 4- and 6-year-olds through five one-hour training sessions over a period of two or three weeks.
The grant-in-aid, worth about 70 million yen, will be used to help the hospital in the provincial capital buy such equipment as stretchers and electroencephalographs
, it said.
