Somatosensorische Homunkuli
Published: 17.08.2011
Im somatosensorischen Cortex sind nicht alle Körperregionen gleich stark repräsentiert. Wichtige Areale wie Gesicht, Hände oder Füße erhalten mehr Raum auf der somatosensorischen Karte, hier verdeutlicht in Homunkuli von Mensch und Tier. Mehr dazu wie der menschliche Körper im Gehirn abgebildet ist und wie sehr die Karte des des somatosensorischen Cortex wandelbar ist können Sie in unserem Artikel Das flexible Gehirn lesen.
Cortex
cortex cerebri
Cortex refers to a collection of neurons, typically in the form of a thin surface. However, it usually refers to the cerebral cortex, the outermost layer of the Cerebrum. It is 2.5 mm to 5 mm thick and rich in nerve cells. The cerebral cortex is heavily folded, comparable to a handkerchief in a cup. This creates numerous convolutions (gyri), fissures (fissurae), and sulci. Unfolded, the surface area of the cortex is approximately 1,800cm².

Cerebrum
telencephalon
The cerebrum comprises the cerebral cortex (gray matter), the nerve fibers (white matter), and the basal ganglia. It is the largest part of the brain. The cortex can be divided into four cortical areas: the temporal lobe, frontal lobe, occipital lobe, and parietal lobe.
Its functions include the coordination of perception, motivation, learning, and thinking.
