MDU RANK LIST IS OUT

-
now the waiting time  is complete and the mdu rank is disclosed and finally the result breakover is shows it is clearly defined the result is being affected by the even semester ghost is totally patronized the students and the hauuuwa of the even semester is done their job  but but but over on this  maximum no of the student get clears the result with verry good percentages  so many hurdles are comes out but now the rank is declared and are below ↓

brain monitoring Electroencephalography (EEG)

-
Image
Electroencephalography  ( EEG ) is an  electrophysiological  monitoring method to record electrical activity of the  brain . It is typically noninvasive, with the  electrodes  placed along the  scalp , although invasive electrodes are sometimes used such as in  electrocorticography . EEG measures voltage fluctuations resulting from  ionic current  within the  neurons  of the  brain . [1]  In clinical contexts, EEG refers to the recording of the brain's spontaneous electrical activity over a period of time, [1]  as recorded from multiple  electrodes  placed on the scalp. Diagnostic applications generally focus either on  event-related potentials  or on the  spectral content of EEG. The former investigates potential fluctuations time locked to an event like stimulus onset or button press. The latter analyses the type of  neural oscillations  (popularly called "brain waves") that...
