Mole's Star

Product Information

Consequently, the ability of the star to rapidly determine location and identity of objects is enhanced by small receptive fields and its associated collateral inhibition system that constrains cortical neurons with short latency responses.

Other important fact of the representation of the star in the cerebral cortex is that each hemisphere had clearly visible set of 11 stripes representing the contralateral star. Mechanosensory organs of moles, shrew-moles, and desmans: a survey of the family Talpidae with comments on the function and evolution of Eimer's organ".These domes, known as Eimer’s organs, are the only type of receptor organs found in the star of the star-nosed mole, which proves that the star-like structure has clearly a mechanical functioning. This large amount of specialized receptors makes the star ultrasensitive – about 6 times more sensitive than the human hand, which contains about 17,000 receptors. Rays 1 through 9 each have about 4 fibers per Eimer's organ, while rays 10 and 11 have significantly higher innervation densities of 5. This means that tactile information from the environment is transmitted to the somatosensory neocortex rapidly.

One one level its a sweet tale about mole wanting to brighten up his home, and how he goes about that, and on another level, it’s a book about consequences and sharing.

There is rich opportunity for exploring the plot , literary devices, social issues and art with primary age children making this a potential powerhouse book for educators. However, it's worth noting that I think the premise of the book will appeal more to certain audiences than others, it has a gentle but political message about the importance of community and sharing instead of hoarding and profiting from wonderful things to ourselves, that no one person has the right to take the wonders of the earth from others, but if mistakes are made then teamwork and forgiveness can plough a path to happiness again. Stimuli cause depolarization of the receptor membrane, resulting in a receptor potential and therefore a current towards the node of Ranvier. It is associated with a Merkel cell- neurite complex at the base of the cell column, a lamellated corpuscle in the dermis just below the column and a series of free nerve endings that originate from myelinated fibers in the dermis, run through the central column and end in a ring of terminal swellings just below the outer keratinized skin surface. Other mole species also possess Eimer's organs, though they are not as specialized or numerous as in the star-nosed mole.
