類似度に基づいてデータをグループ分けする機械学習の手法。
The Murata Laboratory belongs to Waseda University’s School of Advanced Science and Engineering, Department of Electrical and Information Biotechnology, and is a cutting-edge laboratory that explores the possibilities of data. Against the backdrop of rapidly evolving computer technology and the accumulation of vast amounts of data, we aim to use probability, statistics, and machine learning methods to elucidate the essence of data and gain insights that will be useful to society.

Extracellular recording of single neurons has been one of the key techniques to investigate neural activity in freely behaving animals for more than 60 years. Improvement of recording technology including electrode profiles, configurations, and driving mechanisms has led to the significant increase of the number of simultaneously recorded neurons, yielding important findings in neuroscience. In this lecture, we will review the basic physics of extracellular electrophysiology, the types of signals that can be recorded by extracellular electrodes, and the technical developments of extracellular electrophysiology in freely behaving animals. The lecture will also cover essential concepts in sleep and memory as well as computational methods for the analysis of electrophysiological data. We will showcase a research example of detection of memory reactivation together with neural networks modeling of memory function.
