• vibrissal
  • Thus, an estimate for the total number of sensory nerve cells serving the mystacial vibrissal array on the face of a rat or mouse might be 25,000. (wikipedia.org)
  • Paired with earlier results suggesting similar patterns of vibrissal movement, this strongly implies that early therian (marsupial and placental) mammals were whisking animals that actively controlled their vibrissae. (biologists.org)
  • The structures in the skin that bear the vibrissae are referred to as vibrissal follicle-sinus complexes (F-SCs) [ 13 , 14 ], as the highly innervated hair follicle is surrounded by an ample blood sinus complex and a dense tissue capsule. (royalsocietypublishing.org)
  • sensory
  • However, vibrissae are different from other hair structures because they grow from a special hair follicle incorporating a capsule of blood called a blood sinus which is heavily innervated by sensory nerves. (wikipedia.org)
  • The rodent vibrissae system is one of the most used experimental models for the study of the sensory information handling. (hindawi.com)
  • seals
  • Even female and subadult male elephant seals can be distinguished from-other vagrant seals within their range by body size, size and proportions of the head, pelage coloration, prominence and colour of vibrissae, and relative size of the eyes. (fao.org)
  • nose
  • The mystacial area and nose are fleshy and rather pointed on females and young subadult males. (fao.org)
  • system
  • Despite the importance of the sematosensory system, little is known about how proper connections between vibrissae and innervating neurons are made. (wiley.com)
  • mice
  • The organisation of the mystacial vibrissae and corresponding barrels is so consistent that there is a naming convention to identify each whisker in rats and mice. (wikipedia.org)
  • Mice of either sex were randomly assigned to either vibrissa or auditory control training groups ( Fig. 1 A , B ). (jneurosci.org)
  • animals
  • Foveal whisking occurs when animals thrust all their vibrissae forward to palpate an object ahead of them, as occurs when they try to detect a landing on the far side of a gap. (wikipedia.org)
  • groups
  • Vibrissae (derived from the Latin "vibrio" meaning to vibrate) typically grow in groups in different locations on an animal. (wikipedia.org)
  • Vibrissae of different groups may vary in their anatomical parameters and in their operation, and it is generally assumed that they serve different purposes in accordance with their different locations on the body. (wikipedia.org)
  • several
  • They show that EphA4 is expressed most highly in the ventral whisker pad during vibrissae specification and innvervation, while several EphA4 ligands are expressed on innvervating trigeminal axons. (wiley.com)
  • studies
  • and since most behavioral studies of texture discrimination involved contact with both vibrissae ( Carvell and Simons, 1990 , 1995 ). (jneurosci.org)
