Validation of baseplate-derived ambulatory activity by comparison to manual tracking.

<p>Data shown are from the ventral midline RFID placement following ‘shielding upgrade’. (a) Ambulatory movement (distance travelled) of the rats derived from the baseplate RFID reader (red line) is overlaid with distance travelled measured by manual tracking (blue line) over a 60 min period (plotted in 1-minute bins; mean of 6 rats ± SEM), for each RFID implantation site. (b) Correlation plot of baseplate and manual activity data (distance travelled) from the 6 rats plotted in 15-minute bins from the 60-minute monitoring period. The dotted line is the equivalence line. (c) Bland-Altman plot showing the average difference between the baseplate and manual measurements as a function of the average reading.
