Formen Sehen

Published: 12.11.2010

Im primären visuellen Cortex sind 200 Millionen Nervenzellen damit beschäftigt, Ordnung in das Chaos der eingehenden Signale zu bringen. Eine wichtige Rolle dabei spielen Ecken und Kanten. Und Zellen, die auf ganz bestimmte Winkel reagieren.

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.
