easyTEL+ implantable telemetry can acquire multiple biopotentials (EEG, EMG, ECG, EOG) and pressures (arterial, ventricular), temperature, activity, and respiratory rate in small and large animals. While the small animal implants acquire up to 2 biopotentials and one pressure for up to 150 days, the large animal implants can record 4 biopotentials and 2 pressures for up to 295 days.
A major advantage of fully implantable systems is their compatibility with water-based tests (i.e. Morris Water Maze, Forced Swim Test). Transmitter state (on/sleep) and reconfigurable settings (sampling rate, resolution, transmission power, transmission frequency, etc.) can be controlled wirelessly. This reduces human interaction, thereby increasing the likelihood or the animal’s natural state during behavioral testing. The electrodes on these implants can have a bipolar or common ground configuration.
Examples of an easyTEL+ system set up to acquire physiological data during various behavioral tests are shown below.
