Control center brain

Our thinking organ processes vast amounts of information and regulates complex body processes

The brain processes stimuli from the sensory organs

The brain processes sensory impressions, influences our body functions, stores memories and coordinates our actions. Together with the spinal cord, the organ forms the central nervous system (CNS). The brain tissue consists of nerve cells and supporting cells (glial cells). The brain is enveloped by meninges. On average, it weighs around one and a half kilograms.

You can find many details about the anatomy of the brain in our body atlas.

The brain is divided into different areas, including


The cerebrum consists of two halves of the brain. They are connected by the so-called beam. Each half is divided into rags, including one below

  • Frontal lobes
  • Parietal lobe (parietal lobe)
  • Temporal lobes
  • Occipital lobe (occipital lobe)

Areas of the heavily furrowed cerebral cortex specialize in certain functions. For example, there are regions in the frontal lobe that are primarily responsible for motor skills.In the occipital lobe there is, among other things, the so-called visual cortex, which processes sensory impressions that we perceive through the eyes.


The diencephalon contains, among other things, the thalamus. It is an important control center and at the same time fulfills a filter and readout function in that it does not pass all stimuli on to the cerebrum. The hypothalamus controls components of the hormonal system and the non-voluntary (vegetative) nervous system.


The cerebellum is located behind the cerebrum. Among other things, it plays an important role in our equilibrium system and in the regulation of movements.

Brain stem

The brain stem regulates many vital functions such as breathing and circulation, as well as important reflexes, for example the swallowing and coughing reflexes. The brain stem extends down into the spinal cord.
