The Animal Location Tracker (ALT) provides measurements of the movement of our Subcutaneous Transmitters (SCTs), which in turn permit us to identify individual animals in video recordings. Our Video Blob Tracking (VBT) software applies blob-tracking analysis to the video to obtain the coordinates of each animal or animal-like object in the field of view. We calculate the correlation between the movement of each blob and the movement of each SCT. This correlation permits us to identify which SCT corresponds to which blob, provided the blobs are moving. If they are stationary, we use the pre-existing identification provided by the ALT, knowing that the association of SCTs and blobs will not change until the animals move and disappear or occulde one another.
The ALT makes it possible to watch and identify co-habiting and socializing animals, while the implanted SCTs provide simultaneous EEG recording from the watched animals. Fully-automated analysis of animal activity and social interaction may now be performed along with fully-automated event detection in EEG, such as automated association of spike-waves with decision making or seizure spikes with convulsions.
Animal Location Tracker (A3032): An array of coils to detect power from subcutaneous transmitters and so measure the movement of these transmitters.
Animal Cage Camera (A3034): A camera with variable white and infra-red illumination for recording video of animals in cages.
Videoarchiver Tool: Manual for the Videoarchiver, a LWDAQ Tool, which records video from an Animal Cage Camera in such a way that it may be played back synchronously with EEG and ALT recordings.
Videoarchiver Libraries: Archive of libraries for MacOS, Linux, and Windows necessary to run the Videoarchiver in LWDAQ. Download, decompress, and place the Videoarchiver folder in LWDAQ.app/Contents/ to make LWDAQ.app/Contents/Videoarchiver.
