Smart home-cage for combined optogenetics and electrophysiology

We have previously developed the first fully wireless head mounted device to combine optical stimulation for optogenetics and electrophysiological recording within a single device. This system enables to activate and track brain activity in freely moving rodents in real time using a new microelectronic design and dedicated signal processing algorithms recently invented by Dr Gosselin at ULAVAL. This is the only tool to enable circuits' analysis in awake and behaving rodents, with high spatial resolution and at millisecond time scale, through large-scale electrophysiology technology combined with optogenetic capabilities, which is key for research. The researchers from all around the world need such a tool to advance knowledge of brain functions and to develop novel therapeutics against brain diseases.
