AB -  NUMBER JULY, 1965 AN ELECTRONIC APPARATUS FOR RECORDING MOVEMENT IN SMALL ANIMALS' W. J. MCCLELLAND UNIVERSITY OF WESTERN ONTARIO Several types of apparatus have been employed to record the movement of small animals. Other than those systems which require attached or embedded leads or the use of radioactive materials, most instruments are variations of the treadmill, such as a nutating annular cage (Kissel, 1963) or versions of the tambour stabilimeter, such as a transducer system (Davis and Ellison, 1964) or a magnetic pick-up device (Mitchell, 1959). Advantageous as these instruments are for recording general activity over long periods of time, they are not sensitive in differentiating relatively subtle changes in the type and extent of movement. A radar-like ultrasonic device (Peacock and Williams, 1962) overcomes any need for mechanical coupling between the animal and the recording system, but presents other problems of frequency interference and reflection, threshold determination, and vibration artifacts. This paper describes an electronic apparatus based on capacitance sensing, for recording the movement of small animals. In contrast with the previous uses of capacitance sensing, such as the digital "on-off" recording of the presence of a snake on grids at various levels of a vertical cage
