New Bluetooth-Low-Energy-Based Wireless Neuronal Recording System
Scientists have now created a compact, lightweight, Bluetooth-low-energy-based wireless neuronal recording system.
The wireless system was developed by researchers from the Department of Electrical and Electronic Information Engineering, Department of Computer Science and Engineering, Department of Applied Chemistry and Life Science, and the Electronics-Inspired Interdisciplinary Research Institute (EIIRIS) at the Toyohashi University of Technology.
The weight of the system is less than 3.9 g and it measures 15 × 15 × 12 mm
3 together with the battery. The system offers the benefits of ideal versatility, high signal quality, and low cost than wired recording using a commercial neurophysiology system. The study was published online on January 8

Overview:
A color illusion that strongly induces color contrast effect has been found by a research team at the Toyohashi University of Technology Department of Computer Science and Engineering, and Electronics-Inspired Interdisciplinary Research Institute (EIIRIS). The powerful visual illusion clarified a century-old contradiction relating to simultaneous color contrast theory. Through a human psychophysical experiment, the team demonstrated that the presence or absence of flanking contours formed from extremely thin white lines could be used to switch between contradictory visual phenomena (Figure 1), enabling consistent explanation for both discrepant theories. This solution alters theories of visual computatio
