Construction of a micro-projection system using a high-speed DMD

Abstract

Brain research is being conducted around the world. However, the mechanism by which simple neuronal activities are combined into a network to realize sophisticated brain functions remains largely unexplored. For this reason, research in the field of neuroscience is being conducted on C. elegans, which has an extremely simple brain and whose entire neural network has been completely elucidated. Although C. elegans is a relatively simple organism, it shares many essential biological characteristics with humans. Understanding the biology of the nematode C. elegans will develop into an understanding of humans. In the study of the nervous system, recent years have seen rapid progress in a field called optogenetics, in which light can be used to stimulate the nervous system through genetic manipulation. Therefore, in this study, we constructed a low-latency and high-speed microprojection system for manipulating neural activity in the nervous system of the nematode C. elegans.
