Abstract

The elucidation of physio-pathological mechanisms expressed by a neuronal network over extended time scales (i.e., from hours to weeks) is the goal of many neurophysiological and neuropharmacological in vitro studies. In this context, a challenging technological requirement is the establishment of an experimental setup able to collect long-term neuronal signals. In this work we report the development of a compact environmental chamber designed to perform prolonged recordings of the bioelectrical activity exhibited by neuronal networks grown on MicroElectrode Arrays (MEAs). To reproduce an environment suitable for cells growth (temperature, pH and humidity) the chamber was coupled with a temperature control system and an air humidifying module. Validation tests demonstrated that the environment inside the portable chamber is comparable to standard cell incubators environment. To collect neuronal extracellular signals, custom multichannel pre-processing boards have been developed and integrated with the chamber. With this equipment, we were able to reliably record spontaneous neuronal electrical activity from hippocampal cultures grown inside the chamber for several hours, which is not possible with the standard MEA recording setup due to environmental fluctuations. This system can collect multichannel data from neuronal cultures over long periods, providing an effective solution for long-term studies of neural activity.
