Recording of acceleration data while a rat performs a go/no-go task based on a tone. A: example trial shows the ability to extract the animal's reaction time from the accelerometer data. Traditionally, the only information available is the time a sensor on the nose-poke is triggered, but the accelerometer trace provides a significantly more accurate measure of reaction time. B: a histogram of the reaction time calculated using the accelerometer and nose poke. The mean and variance of the reaction time calculated from the accelerometer (red) is less than time taken to enter the nose poke (blue).
