Supplementary Figure 6: Comparison of the motion detected by the motion-detection metric derived from MiniLFM raw data, and the transverse acceleration as measured by an accelerometer.
From: High-speed volumetric imaging of neuronal activity in freely moving rodents
Top trace: Acceleration metric derived from a miniature accelerometer attached to the MiniLFM sensor circuit board (Online Methods) during a 5-minute trial of free behavior on a linear track. Raw signal was processed by hi-pass filtering, re-binning and taking the modulus of the transverse acceleration component (i.e., in the sensor plane). Bottom trace: Motion metric derived from MiniLFM raw data of the same trial. Metric is based on range of difference frame values (Online Methods).
