'Douglas J. Bakkum' 'Urs Frey'] Microelectrode arrays and microprobes have been widely utilized to measure neuronal activity, both in vitro and in vivo. The key advantage is the capability to record and stimulate neurons at multiple sites simultaneously. However, unlike the single-cell or single-channel resolution of…

Implantable neural interfaces for central nervous system research have been designed with wire, polymer, or micromachining technologies over the past 70 years. Research on biocompatible materials, ideal probe shapes, and insertion methods has resulted in building more and more capable neural interfaces. Although the…

'Sotiris C. Masmanidis' 'Hiromu Tanimoto'] Extracellular electrode arrays can reveal the neuronal network correlates of behavior with single-cell, single-spike, and sub-millisecond resolution. However, implantable electrodes are inherently invasive, and efforts to scale up the number and density of recording sites must…

'Jaclyn Lundberg' 'Michael J. Burns' 'Thomas C. Chiles' 'John P. Christianson' 'Michael J. Naughton'] Recent progress in the study of the brain has been greatly facilitated by the development of new tools capable of minimally-invasive, robust coupling to neuronal assemblies. Two prominent examples are the…

'Ilya Bezprozvanny' 'Olga Vlasova' 'Rosa Garriga'] In recent decades, microelectrodes have been widely used in neuroscience to understand the mechanisms behind brain functions, as well as the relationship between neural activity and behavior, perception and cognition. However, the recording of neuronal activity over a…

'Nenggan Zheng' 'John A. Rogers' 'Kewang Nan'] Millimeter-scale animals such as Caenorhabditis elegans, Drosophila larvae, zebrafish, and bees serve as powerful model organisms in the fields of neurobiology and neuroethology. Various methods exist for recording large-scale electrophysiological signals from these…

'Kerstin Doerenkamp' 'Björn M. Kampa' 'Simon Musall' 'Markus Rothermel' 'Andreas Offenhäusser'] Chronically implanted neural probes are powerful tools to decode brain activity however, recording population and spiking activity over long periods remains a major challenge. Here, we designed and fabricated flexible…

'Matthew R. Angle' 'William Wray' 'Yifan Kong' 'Jan Müller' 'Andreas Hierlemann' 'Nicholas A. Melosh' 'Andreas T. Schaefer'] Mammalian brains consist of 10s of millions to 100s of billions of neurons operating at millisecond time scales, of which current recording techniques only capture a tiny fraction. Recording…
