Abstract

This paper introduces Ultra-Flexible Tentacle Electrodes (UFTEs), a novel high-density electrode array for long-term neural recordings. UFTEs achieve high signal-to-noise ratios and unit yields while minimizing tissue damage, enabling months-long tracking of individual neurons and neuronal ensembles across multiple brain areas in freely moving rodents. The study reveals distinct classes of neuronal ensembles, some with surprisingly long lifetimes, highlighting the potential of UFTEs for advancing our understanding of brain dynamics.
