This study is to examine the possibility of a brain-scientific approach of the fashion-store visual merchandising display (VMD). In marketing area, VMD has become a research topic of interest. However, a few VMD research has been done by using human brain signals. In this work, the hemodynamic responses (HRs) in the prefrontal cortex (PFC) using functional near-infrared spectroscopy were measured...
White matter segmentation is an essential step to study whole-brain structural connectivity via diffusion MRI white matter tractography. One important goal of segmentation methods is to improve consistency of the white matter segmentations across multiple subjects. In this study, we quantitatively compare two popular white matter segmentation strategies, i.e., a cortical-parcellation-based method...
Episodic memory dysfunction is one of the hallmark symptoms of Alzheimer's disease (AD) and mild cognitive impairment (MCI). This cognitive impairment may be related to abnormal brain structure and activity. Functional connectivity mapping (FCM) analysis provides a powerful tool for exploring the topology of human brain function using magnetic resonance imaging (MRI). Thus, it would be advantageous...
Blinking has two functions: to moisturize eyes and as a defensive response to the environment and responses caused by the by mental processes. In this paper, we investigate statistical characteristics of blinks and blink rate variability of 11 subjects. The subjects are presented with a reading/memorization session preceded and followed by resting sessions. EEG signals were recorded during these sessions...
Although EEG-based BCI are very promising for numerous applications, they mostly remain prototypes not used outside laboratories, due to their low reliability. Poor BCI performances are partly due to imperfect EEG signal processing algorithms but also to the user, who may not be able to produce reliable EEG patterns. This paper presents some of our current work that aims at addressing the latter,...
Color change detection is of great importance in the study of automatic visual processing mechanisms. Although the visual mismatch negativity (vMMN) has been widely explored, the importance of induced components and the precise oscillations of EEG signal have been ignored. In the present study, we conducted the event-related (de)synchronization (ERD/ERS) of the EEG oscillatory activities relevant...
The effects of visuospatial selective attention on information processing have been investigated by means of high-density event-related brain potentials (ERP) while the subjects were instructed to covertly attend to one side of the visual field with fixation on the center of the screen. Previous studies have demonstrated the attention-related modulation of the P1 (scalp-positive waves from 90-130...
