Research Abstract

Animal brains swags in vivo. On the other hand, the intracellular recording electrode is fastened on to a base in the experiment. The intracellular recording is necessary for elucidating the information processing in the brain, but the current intracellular recording system does not realize a long-term stable recording in behaving animals. To solve this problem, I will develop a micromanipulator tracking brain micromotion in 3D and aim to simultaneously record the membrane potentials from two neurons in behaving animals.
