Macrovibrissae

WebThe orienting behavior that rats perform with their macrovibrissae has been proposed to conform to a “maximal contact” active sensing strategy (Mitchinson et al., 2007; Grant et al., 2009), such that following a contact, as many whiskers as possible are positioned on to the surface, so as to extract more information.Several aspects of whisker control contribute … WebIn this paper we describe the effects of manipulating two kinds of sensory input in neonatal rats upon the development of the macrovibrissae--that movable subset of the rodent …
