name the largest and most complex part of human brain
cerebrum
title: Human brain text: Human brain The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head. The cerebrum is the largest part of the human brain. It is divided into two title: Human brain text: primates.

It is divided into title: Human brain text: the largest cells (by size of cell body) in the nervous system. The adult human brain is estimated to contain 86±8 billion neurons, with a roughly equal number (85±10 billion) of non-neuronal cells. Out of these neurons, 16 billion (19%) are located in the cerebral cortex, and 69 billion (80%) are in the cerebellum. Types of glial cell are astrocytes (including Bergmann glia), oligodendrocytes, ependymal cells (including tanycytes), radial glial cells and microglia. Astrocytes are the largest of the glial cells. They are stellate cells with many processes radiating from their cell bodies. Some of these processes end as perivascular title: Human brain text: is the outermost membrane of the cortex. The living brain is very soft, having a gel-like consistency similar to soft tofu. The cortical layers of neurons constitute much of the brain's grey matter, while the deeper subcortical regions of myelinated axons, make up the white matter. The cerebrum is the largest part of the human brain, and is divided into nearly symmetrical left and right hemispheres by a deep groove, the longitudinal fissure. The outer part of the cerebrum is the cerebral cortex, made up of grey matter arranged in layers. It is thick, and deeply folded to give a title: Paleocortex text: Paleocortex In anatomy of animals, the paleopallium or paleocortex is a region within the telencephalon in the brain which is younger in an evolutionary sense (i.e. phylogenetically) than archicortex (or archipallium), but phylogenetically older than neocortex (or neopallium). Paleocortex (or paleopallium) and the archicortex (or the archipallium, which is a synonym) of the cerebral cortex together constitute the allocortex or the heterogenetic cortex. The distinction for what is called neocortex or isocortex, which comprises most of the human brain (about 90%), is made from the number of cellular layers that comprise the structure. Neocortical tissue comprises six distinct cell layers,
