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. We apply blob-tracking to the video of cohabiting animals, and so obtain the coordinates of each animal in the field of view. We calculate the correlation between the movement of each blob and the movement of each SCT over an interval of roughly ten seconds. 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 possible the video tracking of co-habiting and socializing animals, along with simultaneous EEG monitoring with SCTs. The wealth of information available in video may now be associated with individual animals through their identifying SCT channel numbers. 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.
