The muzzle is wide with puffy whisker pads. A dreaming cat will sometimes have rapid, uncontrolled facial, whisker, paw, and abdominal movements. Reflow to melt solder or tin plate to relieve surface stress lowers whisker incidence. They have conspicuous cheekbones and light, large whisker pads. These afferents are mechanoreceptor cells that fire in response to whisker deflection. Deflection-based firing neurons can sustain their response throughout the deflection of the whisker. They then project back to the whisker motor and somatosensory cortex. Silicon required more pressure than the cat whisker contact, although not as much as carborundum. This cortical-claustral-cortical circuit plays a role in whisker movements for orientation and palpation. Ohl investigated why the cat's whisker functioned so well. An additional advantage of underfill is that it limits tin whisker growth. They were very unreliable, requiring frequent adjustment of the cat's whisker and offered no amplification. Cell bodies of the whisker primary afferents are found here. The shop was called Stewart Brothers Wet Whisker. In 1983, the name again changed from Stewart Brothers Wet Whisker to Stewart Brothers Coffee.
