Double membrane that separates the nucleus from the cytoplasm

Double membrane that separates the nucleus from the cytoplasm is from Nuclear Envelope

Explanation

The nuclear envelope consists of a pair of lipid bilayer membranes, an inner nuclear membrane, and an outer nuclear membrane. The area connecting the membranes is termed as the perinuclear space. The double layer that separate the content of the nucleus and cytoplasm is called nuclear envelope. This envelope is riddled with holes called nuclear pores that allow specific types and sizes of molecules to pass between the nucleus and the cytoplasm.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
