Marginal Sulcus
In neuroanatomy, the marginal sulcus (margin of the cingulate sulcus) is a Sulcus (neuroanatomy), sulcus (crevice) that may be considered the termination of the cingulate sulcus. It separates the paracentral lobule anteriorly and the precuneus posteriorly. Additional images File:Marginal sulcus animation small.gif, Position of marginal sulcus (shown in red).

Neuroanatomy
Neuroanatomy is the study of the structure and organization of the nervous system. In contrast to animals with radial symmetry, whose nervous system consists of a distributed network of cells, animals with bilateral symmetry have segregated, defined nervous systems. Their neuroanatomy is therefore better understood. In vertebrates, the nervous system is segregated into the internal structure of the brain and spinal cord (together called the central nervous system, or CNS) and the routes of the nerves that connect to the rest of the body (known as the peripheral nervous system, or PNS). The delineation of distinct structures and regions of the nervous system has been critical in investigating how it works. For example, much of what neuroscientists have learned comes from observing how damage or "lesions" to specific brain areas affects behavior or other neural functions.
