However, they showed an impaired ability to distinguish textures by touch, indicating that they were not processing sensory messages correctly.
The underlying cortical coding mechanisms responsible for the formidable capability of rodents to distinguish texture coarseness have been studied extensively, mainly in granular and infra-granular cortical layers using multi- and single-unit recordings (Guic-Robles et al., 1992; Arabzadeh et al., 2003, 2006; von Heimendahl et al., 2007; Diamond et al., 2008a; Morita et al., 2011).
Slickness, roughness, and springiness were the major traits that distinguished the texture of varieties.
Finally, our model does not explain how occlusion-based junctions can be distinguished from texture-based junctions.
Above that thickness loses in visibility and light conditions make it difficult to distinguish small textures in detail.
Now a new study demonstrates that sweeping a whisker across a surface allow rats to distinguish between textures that confound even human fingertips.
They suspect that this explains the effect: Merkel cells are spaced more densely in smaller hands, giving those hands the ability to distinguish finer textures.
By giving the monkey rewards when it identified the right texture, the researchers discovered that it took as few as four training sessions for the animal to consistently distinguish the textures from one another, even when the researchers switched the order of the visually identical disks on the screen.
One of the key functions of whiskers is to help animals to distinguish between textures.
For this, the FD will be calculated with the ImageJ always between 0 and 2, not distinguishing different textures.
