WebSep 15, 2013 · The results of two manual tracking examples are shown (A,B). Two macrovibrissae (blue, left whisker field; green, right whisker field) and one genal whisker (red) during two episodes of regular whisking. The genal whisker moves synchronously with the macrovibrissae, but at a lower amplitude, during some but not all whisk cycles. WebApr 9, 2014 · Rodents use their whiskers to detect a variety of tactile features of their environment. They do so by using two functionally distinct whisker systems: the macrovibrissae and microvibrissae.
