The present experiment shows that the position of the arm is represented in the premotor cortex of the monkey (Macaca fascicularis) brain by means of a convergence of visual cues and proprioceptive cues onto the same neurons. These neurons respond to the felt position of the arm when the arm is covered from view.
The muskrat tail actually has some flatness, but vertical like a boat rudder. Muskrats do not cut down trees. Muskrats and beaver are the only mammals that build their home in the water, but the muskrat lodge is smaller.They often dig dens into the bank; again the muskrat opening is smaller. Muskrats do not store food for the winter as beaver do and a harsh winter can greatly decrease a muskrat population.Muskrats are more prolific breeders capable of multiple litters in one season whereas beavers have one litter annually.uskrats do not store food for the winter as beaver do and a harsh winter can greatly decrease a muskrat population.

General Description. Sometimes mistaken at first glance for the beaver, the muskrat's small size and rat-like tail are the most immediate identification marks. Muskrats weigh from two to four pounds (0.9â1.8 kg).
