Accurate and affordable assessment of physiological and pathological tremor in rodents using the accelerometer of a smartphone. J Neurophysiol 122: 970–974, 2019. First published July 10, 2019; doi: 10.1152/jn.00281.2019.A unit error for the estimation of elastic stiffness was discovered in the manuscript.The second sentence in the third paragraph of materials and methods should be: “The elastics that were changed for each new experiment had stiffnesses of 0.5, 0.4, 0.25, and 0.1 N/mm.”Similarly, the legend for Fig. 1C should be: “Arrows point at peaks at 8–9 Hz that were detected with low-stiffness elastics (0.1–0.4 N/mm).”Accordingly, Fig. 1 has been changed to include the correct numbers and units for C–F.Importantly, this correction does not affect any conclusions or interpretations reported in the manuscript.Fig. 1.Experimental setup. A: a custom-built cage of light material (15 × 15 × 20 cm) suspended from a rack by rubber bands. A smartphone is attached underneath the cage. Acceleration is monitored with an application (VibSensor). B: mean spectrogram of acceleration before and during harmaline-induced tremor (n = 11 animals). Harmaline was injected 1 min before the start of the recording. C–F: power spectral density (PSD) plot of harmaline-induced tremor obtained with cage suspended by elastics of different stiffnesses. C: x-axis data. Arrows point at peaks at 8–9 Hz that were detected with low-stiffness elastics (0.1–0.4 N/mm). D: y-axis data. E: mean of x- and y-axis data. F: z-axis data. Several peaks are present (arrows).Download figureDownload PowerPointThis article has no references to display.
