The LAM10/16/25 Locomotor Activity Monitor uses infrared beams to characterize the pattern of movement in each of 32 individual tubes or vials. A planar array of 3 or 9 radial beams crosses each tube at its midpoint, and when animals in the tube move through the array, the beams are interrupted and then registered as counts. Over the course of an experiment, which may last for days or weeks, the counting circuits continuously monitor each tube for activity, and at periodic intervals upload their count totals to the host computer for storage and analysis. This daily record provides a good measure of both the intensity of locomotor activity and the relative periods of rest in each tube. The unit is available in 3 tube sizes: 10, 16, and 25mm diameter, and either 3 or 9 beams. The 3-beam unit is appropriate for animal species with a standing height of at least 1/2 of the tube diameter. Otherwise the 9-beam high-resolution unit should be used to insure reliable detection. Populations of drosophila melanogaster up to about 20 individuals may be accurately characterized by the LAM25H, which uses 25mm vials and 9 beams. These units may be operated with horizontal tubes as shown, or rotated back 90 degrees to orient the vials vertically. An optional tube support plate mounts on the rear of the unit to register and support the tubes when vertical. A 3-board version of each unit is available for additional measurement fidelity. These 3- board stacks, the LAM10H-3. LAM16H-3, and LAM25H-3, measure the activity in each tube with 3 independent beam arrays spaced at 10mm along the tube axis. The unit is compatible with the PSIU9 hardware network and the DAMSystem3 data collection software application. Up to 120 monitors may be connected to a single system of this type
