Brain Mapping Using Nanotechnology

Abstract

Electroencephalography deals with the recording and study of electrical activity of the brain. By means of electrodes attached to the skull of a patient, the brain waves can be picked up and recorded. The brain waves are the summation of neural depolarizations in the brain due to stimuli from the five senses as well as from the thought processes. On the surface of the brain, these voltages are about 10 mv. Here, we can use sensors material is nanosensors. These sensors are looking very small size compare with now a days available sensor in electroencephalography. Nanosensors are very accuracy measuring the voltages of the brain waves.
