Can the brain feel it? The world's smallest extracellular needle-electrodes
25 Oct 2016
Single 5 μm diameter needle electrode block modules for unit recordings in vivo
A research team from Toyohashi University of Technology developed the world's smallest 5-µm-diameter low-invasive needle electrodes, which are assembled on 1 × 1 mm2 blocks. Surprisingly, high quality neuronal signals from a mouse's cortex were stably recorded for a long period. Their new electrode device reduces the total invasiveness to brain tissue in vivo and realizes stable neural recordings, thus enhancing opportunities for needle-electrode device technology in neurophysiology.
