A data acquisition and analysis system for use with multi-electrode arrays in the development of a retinal prosthesis for degenerative retinal diseases
… for the purpose of testing prototype prosthesis electrode arrays. These unique flexible arrays, produced on a biocompatible polyimide substrate, incorporate 16 extremely small platinum electrodes of diameter 5 microns which are signifcantly smaller than those used by other groups. Using the …

Characterization of neurite growth on a novel neurotube platform
… neurons in vitro is being continually studied: multi-electrode arrays allow for the development and maintenance of functioning neural networks that can be programmed to complete a task; and yet, after ninety years of exploring electrical dimensions of tissue slices and cultures, there is still a …

Comparative studies of brain developmental timing and progression using 3D stem cell models
… brain organoid slice cultures on high density multi-electrode arrays. We develop and design technologies for longitudinal recording of brain organoids in-situ at the airliquid interface, and provide the first evidence of circadian rhythmicity to electrophysiological activity in brain organoids. …

Monitoring of cerebellar injury using micro ECoG signals in ketamine/xylazine treated rats
… with chronically implanted, flexible-substrate, multielectrode arrays in rats were collected and analyzed with the motor cortex signals. The power spectra and the intercontact coherence plots of the spontaneous activity in the awake-quiet animals extended up to 800 Hz in the cerebellum and only …

Spatio-temporal structure of thalamically evoked activity in the barrel cortex
… were recorded in the ‘barrel’ cortex with multi-electrode arrays, while electrical stimulation of the thalamocortical pathway simulated incoming sensory information. <br>Glutamatergic responses to thalamocortical stimulation spanned multiple barrels starting 1–2 ms after the first fibre …

Master regulators of neuronal maturation in NGN2 reprogrammed iPSC-derived iNeurons
… early synchronous burst activity, as measured on multi-electrode arrays (MEAs). Candidate master-regulators of iNeuron maturation were identified using TF motif prediction tools and a dataset combining ATAC-seq and RNA-seq analysis of a granular time-course experiment during NGN2 reprogramming, in …

Methods for studying the neural code in high dimensions
… last two decades technological developments in multi-electrode arrays and fluorescence microscopy have made it possible to simultaneously record from hundreds to thousands of neurons. Developing methods for analyzing these data in order to learn how networks of neurons respond to external …

Optical Nanoantennas Integrated with 3D Microelectrode Arrays: Hybrid Photonic-Electronic Modalities for Nano-Bio Interfacing
… integrated biochemical and bioelectrical sensor arrays to create a multi-modal platform for complex systems biological research. For the biochemical sensor, we introduced a tunable optical nanoantenna that is driven wirelessly by incident laser light (photons) to create a highly localized …

Novel Methods for Recording and Analysing High-Density EMG Signals of the Hand & Forearm
… and analysed using non-invasive recording electrodes in a technique known as surface electromyography (sEMG). Key information about the muscles can then be extracted from EMG signals using signal processing techniques and used in various applications ranging from electrophysiology studies …

MICROELECTRODE ARRAY FOR CAPACITIVE TRANSDUCTION OF RETINAL RESPONSES
… techniques of neural activity sensing employ multi-electrode arrays (MEAs) that typically incorporate metal electrodes and measure currents via an electrochemical junction, leading to corrosion and charge transfer across the electrode-tissue interface. High-density neural interface technology …
