Abstract

In this paper, investigations of brain activity response from experimental works, based on optic flow and wavelet using near infrared spectroscopy are presented. The outcomes of our research project showed that optical flow is a proper technology for the investigation of brain activity based on near-infrared spectroscopy (NIRS). Our research also showed that the results in the temporal domain, spatial domain, and wavelet domain are coherently supporting the analyses of our experimental results. Our wavelet analysis can obtain the majority of the brain activity for the spatiotemporal distribution. Based on the spatiotemporal analysis, we can clearly observe the existence of the dominant channel (DC), which plays a critical role in the brain activity. The spatial distribution of the cortical activity origin can be described by the hemodynamic response in the cerebral cortex after evoked stimulation using near infrared spectroscopy. Further application is expected in the next research outcomes

OtherThe sixth IEEE RAS/EMBS International Conference on Biomedical Robotics and Biomechatronics - BioRob 2016 - is a joint effort of the two IEEE Societies of Robotics and Automation - RAS - and Engineering in Medicine and Biology - EMBS.

BioRob covers both theoretical and experimental challenges posed by the application of robotics and mechatronics in medicine and biology. The primary focus of Biorobotics is to analyze biological systems from a "biomechatronic" point of view, trying to understand the scientific and engineering principles underlying their extraordinary performance. This profound understanding of how biological systems work, behave and interact can be used for two main objectives: to guide the design and fabrication of novel, high performance bio-inspired machines and systems for many different applications; and to develop novel nano, micro-, macro- devices that can act upon, substitute parts of, and assist human beings in prevention, diagnosis, surgery, prosthetics, rehabilitation and personal assistance
