Texture signals in whisker vibrations.
Hipp J, Arabzadeh E, Zorzin E, Conradt J, Kayser C, Diamond ME, König P. Hipp J, et al. J Neurophysiol. 2006 Mar;95(3):1792-9. doi: 10.1152/jn.01104.2005. Epub 2005 Dec 7. J Neurophysiol. 2006. PMID: 16338992 Free article.
Rodents excel in making texture judgments by sweeping their whiskers across a surface. Here we aimed to identify the signals present in whisker vibrations that give rise to such fine sensory discriminations. First, we used sensors to capture …

Gradient of tactile properties in the rat whisker pad.
Gugig E, Sharma H, Azouz R. Gugig E, et al. PLoS Biol. 2020 Oct 22;18(10):e3000699. doi: 10.1371/journal.pbio.3000699. eCollection 2020 Oct. PLoS Biol. 2020. PMID: 33090990 Free PMC article.
This may, in turn, provide a systematic map of separate tactile channels governed by the mechanical properties of the whiskers. To examine whether this map is expressed in a location-dependent transformation of tactile signals into whisker vibrations a …

Whisker-mediated texture discrimination.
Diamond ME, von Heimendahl M, Arabzadeh E. Diamond ME, et al. PLoS Biol. 2008 Aug 26;6(8):e220. doi: 10.1371/journal.pbio.0060220. PLoS Biol. 2008. PMID: 18752356 Free PMC article.
Rats use their whiskers to rapidly and accurately measure the texture of objects. The authors evaluate recent evidence about how whisker movement across a surface produces texture-specific motion signals, and how the signals are represent …

An amplitude modulation/demodulation scheme for whisker-based texture perception.
Boubenec Y, Claverie LN, Shulz DE, Debrégeas G. Boubenec Y, et al. J Neurosci. 2014 Aug 13;34(33):10832-43. doi: 10.1523/JNEUROSCI.0534-14.2014. J Neurosci. 2014. PMID: 25122886 Free PMC article.
These texture-induced whisker vibrations are then replayed via a multiwhisker stimulator while recording neuronal responses in the barrel field of the primary somatosensory cortex (S1bf). ...Fine textural properties are encoded in the time-varying enve …

Dynamic translation of surface coarseness into whisker vibrations.
Lottem E, Azouz R. Lottem E, et al. J Neurophysiol. 2008 Nov;100(5):2852-65. doi: 10.1152/jn.90302.2008. Epub 2008 Sep 17. J Neurophysiol. 2008. PMID: 18799602 Free article.
They do so by actively sweeping their whiskers across surfaces in a rhythmic motion. To determine how textures are transformed into vibration signals in whiskers and how these vibrations are expressed in neuronal discharges, we induced ac …

Frisking the whiskers: patterned sensory input in the rat vibrissa system.
Mehta SB, Kleinfeld D. Mehta SB, et al. Neuron. 2004 Jan 22;41(2):181-4. doi: 10.1016/s0896-6273(04)00002-9. Neuron. 2004. PMID: 14741099 Free article. Review.
Recent papers show that textures may excite intrinsic mechanical vibrations of the vibrissae. Although these vibrations are too rapid to be directly followed by cortical neurons, there is evidence that their speed is encoded by contact-dependent sensor …

Mechanisms of tactile information transmission through whisker vibrations.
Lottem E, Azouz R. Lottem E, et al. J Neurosci. 2009 Sep 16;29(37):11686-97. doi: 10.1523/JNEUROSCI.0705-09.2009. J Neurosci. 2009. PMID: 19759315 Free PMC article.
In their natural environment, rodents use their whiskers to locate and distinguish between objects of different textures and shapes. ...We found that whiskers, being the first stage of sensory information translation, shape transduction by amplifying s …

Millisecond precision temporal encoding of stimulus features during cortically generated gamma oscillations in the rat somatosensory cortex.
Bessaih T, Higley MJ, Contreras D. Bessaih T, et al. J Physiol. 2018 Feb 1;596(3):515-534. doi: 10.1113/JP275245. Epub 2018 Jan 9. J Physiol. 2018. PMID: 29265375 Free PMC article.
ABSTRACT: In the natural environment, tactile exploration often leads to high-frequency vibrations at the level of the sensory organs. Single-unit recordings of cortical neurons have pointed towards either a rate or a temporal code for representing high-frequency tactile …
