EFFECT OF BRIGHT LIGHT ON EEG OCULAR ARTIFACTS
The Electroencephalogram (EEG) reflects electrical functionality of the brain as an advanced medical spectroscopy tool. EEG derives potential from the scalp electrodes, which occurs because of the neuronal firing. It records the strength of neuron firing in relation to time. Generally, the potential of EEG readings are observed to be in the order of microvolt seems as low amplitude and are highly prone to contamination of artifacts from other induced bioelectrical sources exhibited by nearer human organs such as the eye, etc. On precise statistical data analytics study on artifacts contaminating in EEG, it has been found that artifacts contaminating from Ocular organ into EEG has noticeable impact. It is also observed that light plays a vital role in defining amount of ocular artifact contaminating into EEG. This article synchronizes variables of light, ocular organ with EEG and through the statistical ‘Z’ test. Based on the calculated ‘P’ value comparing with 95% of level of Significance (α), confirms the alternate hypothesis that illumination in the EEG recording room also affect ocular artifacts. This is presented along with mathematical model and experimental analysis.
