In mammalian brain anatomy, the prefrontal cortex (PFC) is the cerebral cortex which covers the front part of the frontal lobe.The PFC contains Brodmann areas 9, 10, 11, 12, 46, and 47. third definition of the prefrontal cortex is the area of frontal cortex whose electrical stimulation does not lead to observable movements. For example, in 1890 David Ferrier used the term in this sense.
The blubber helps to keep them warm since they live in a very cold environment.   When harp seals are born, they have a white â¦ fur coat. The fur coat camouflages into the snow to protect them from their enemies on land.
The seal migrates in winter, because it does not have a fur coat to keep it warm if it were able to hibernate, therefore the seal would freeze to death trying to hibernate. Pl â¦ us, the seal needs to go into the water daily to keep its skin hydrated, so it must migrate in winter.It does not hibernate.he seal migrates in winter, because it does not have a fur coat to keep it warm if it were able to hibernate, therefore the seal would freeze to death trying to hibernate.
