Study of brain activity during total sleep deprivation

To study the effect of total sleep deprivation on brain activity using EEG. Methodology: In this paper, the EEG of sixteen subjects (Mean = 21.5; SD = ±2.5) is recorded just after they woke up from sleep. Then, they are sleep deprived for the next twenty-four hours, and the EEG is recorded after sleep deprivation. The raw EEG data is pre-processed. The source localization is performed by a recently developed method- CARSS and sLORETA.Results: (1) The prominence of the right lobe increased from pre to post. (2) The increase in frontal source activation powers and a decrease in parietal is observed from the pre to the post (3) The δ, θ, and α powers increased from pre to post in pre-frontal leads. The left frontal lead showed an increase in α, but a decrease in the right frontal lead is observed. Conclusions: The changes in the source activations and the powers show that there is a change in the way in resting-state neural networks post sleep deprivation.

I. Introduction

Sleep deprivation is known to create a severe loss of concentration, attention and creates an emotional imbalance or hallucinations [1].
