Brain connectivity in spatial orientation task

Abstract

Spatial orientation (SOT) is one of the spatial skill which is required in motor imagery and navigation. A lot of researches have shown underlying neural dynamics during SOT as an effect of spatial transformation strategy, but the consistent findings related to flow of information between designated brain areas are not present. The purpose of the study is to identify flux of information between pairs of channel to identify active hubs during the course of task. The directed transfer function (DTF) method is used to detect alterations in the functional coupling of EEG rhythms (0.5–30 Hz) in different brain cortical areas during virtual reality based perspective taking test. Results confirmed that there were common regions for motor imagery and SOT. It has also shed light on the active role of parietal and occipital lobe in SOT. This study proffers DTF as a useful technique for identifying hubs and flux of information in neuroscience.
