Devices and methods for analyzing rodent behavior

A method of detecting and recording behavioral information of a group of animals in a corral, the method comprising:

• emitting band lights into a base surface of the corral via a plurality of lights positioned around the base surface, the band lights being totally internally reflected within the base surface, the base surface being sensitive to a footprint of one or more animals in the corral such that contact between the footprint of the one or more animals frustrates the totally internally reflected light and refracts the light out of the base surface;
• and
• capturing an image of both a full footprint of a first animal and an image of a toe print of the first animal when the first animal is standing on its toes.
