MICROMAP: LOW-COST MULTICHANNEL ELECTROPHYSIOLOGICAL ACQUISITION SYSTEM

In neuroscience, the extracellular electric potential recordings have led to the understanding of how oscillatory neural activity may reflect important underlying processes involved in both local circuitry processing and large-scale neuronal integration. In addition, diseases (e.g. Epilepsy and Alzheimers`s) often display very characteristic aberrant electrographic behavior, making longitudinal electrophysiological recordings a biomarker-of-choice for long-term evaluation, highlighting unexpected non-physiological states that lead to disease manifestation. Although ideal regarding their predictive and/or diagnostic potential, recordings over long periods present challenges inherent to embedded electronics, signal storage and processing as well as the prohibitive cost for high-quality bioelectric-signal acquisition.
