Rapid Whisker Movements in Sleeping Newborn Rats

Loading video...

Caption: Sample video clips of individual, dual, and multiple whisker twitches are shown, as is an example of a mystacial pad movement. See Figure 1A to orient the whiskers on the snout and to identify each of the 11 whiskers and Figure 1B for the associated quiver plots. Each clip was recorded at 200 frames/s and is played back at 50 frames/s. The white light in the lower-right-hand corner indicates that the experimenter observed twitching of the distal limbs or tail, indicative of active sleep. Note that these clips only show those 11 whiskers that were monitored in these tests.
