In this study, we will show in three visual experiments that there are several brain regions in which induced blood oxygenation level-dependent (BOLD) responses are reproducible between visual tasks and between individual subjects. The reproducible BOLD responses indicate that the specific-sensorial structure (e.g., the lingual gyrus) and non-specific(More)
The study proposes our extended method to assess structure complexity for symbol-free sequences, such as literal texts, DNA sequences, rhythm, and musical input. This method is based on L-system and topological entropy for context-free grammar. Inputs are represented as binary trees. Different input features are represented separately within tree structure(More)
In functional magnetic resonance imaging (fMRI) studies, the blood oxygen level-dependent (BOLD) signal change, in contrast to noise, is typically small (< 5%; e.g., Chen & Small, 2007). Although the quality of acquired image data may be improved by pre-processing images with lowor high-pass filters, classification of voxels into the active/inactive status(More)
