Multi-cage / multi-channel EEG, EMG and activity monitor

ActiveRat is an elegant solution for collecting multi-channel EEG, EMG and activity (infrared detector) data from multiple freely-moving small animals.  The system architecture incorporates amplification and 24-bit analog-to-digital conversion in a single, compact unit located inside or immediately adjacent to the animal housing.  Up to 32 A/D boxes are synchronized but remain galvanically isolated from each other by means of a fiber-optic data daisy chain.  Systems with more than 32 A/D boxes connected to a single host PC are also possible on a custom basis, with a proportional reduction in channels per cage and/or sample rate.
