Název v původním jazyce

The Neural Correlates of Spatial Reference Frames Processing

Popis výsledku v původním jazyce

The research is focused on EEG correlates of the navigation in the virtual tunnel task. Subjects tend to represent the tunnel traverse by the adoption of egocentric or allocentric reference frame (they differ in the origin of the coordinate system) and we explore features in the EEG signal to discriminate the employment of the particular reference frames. The decomposition of the EEG signal to the basic features serves as the input for clustering algorithms. We adopted clustering, hierarchical clustering and self-organizing maps to select the best features discriminating between mentioned reference frames. We identified different activity in the Brodmann area 7 in agreement with the similar study (Gramann et al., 2006), but we also detected other brainareas involved in this task. There are differences for the navigation in horizontal and vertical plane as well.
