Mole's Star

Product Information

Further, the proximity of the star-shaped nose to the mouth greatly reduces the handling time required before food can be ingested and is a major factor in how the star-nosed mole can find and eat food so quickly.

Somatosensory Fovea in the Star-Nosed Mole: Behavioral Use of the Star in Relation to Innervation Patterns and Cortical Representation". This means that tactile information from the environment is transmitted to the somatosensory neocortex rapidly. There are two series of Starstruck books, twelve books in total, written under the pseudonym of Cathy West.

Furthermore, the outstanding speed and precision at which the mole performs may provide insights into the structural design of intelligent machines as an artificial response to the remarkable sensory ability of the star-nosed mole.

The threshold at which the mole can decide whether or not something is edible is of 25 milliseconds: 12 milliseconds to the neurons in the mole’s somatosensory cortex to respond to touch and other 5 milliseconds for motor commands to be conducted back to the star. Stimuli cause depolarization of the receptor membrane, resulting in a receptor potential and therefore a current towards the node of Ranvier. For tonight’s bedtime read, T was attracted by the “beautiful star” when he picked out Mole’s Star by Britta Teckentrup.

These bubbles are then drawn back into the nostrils, so that odorant molecules in the air bubbles are wafted over the olfactory receptors.Electrophysiological experiments using electrodes placed on the cortex during stimulation of the body demonstrated that roughly 52% of the cortex is devoted to the nose. Because the star-nosed mole is functionally blind, the snout was long suspected to be used to detect electrical activity in prey animals, [6] though little, if any, empirical support has been found for this hypothesis. Predators include the red-tailed hawk, great horned owl, barn owl, screech owl, foxes, weasels, minks, various skunks and mustelids, and large fish such as the northern pike, as well as domestic cats.
