Electroencephalogram Measurement in Long-term Adapting Process to Inverted Vision with Candle-like Micro-needle Electrodes

Abstract

This paper describes investigation of the brain activity in an adapting process to inversion vision through electroencephalogram (EEG). In particular, we used Candle-like microneedle electrodes, which does not require any preparation for measuring high-quality EEG. Note that conventional wet electrodes require abrasion of stratum corneum and application of electrolyte paste as preparation for measurement of EEG and they give discomfort to subjects and take time for experimenters. In our previous study, EEG fluctuations of High β，Low γ，and Mid γ waves were detected during the adapting process to inverted vision. In this study, we measured EEG 3 days during the pointing task under an inverted vision state. We detected the long-term adapting process to inverted process using EEG fluctuations and discovered that the detection position had strong correlation with the dominant eye.
