The human brain has several parts, but for now we are just going to be looking at the cerebrum.

Diagram of left side of the brain, with the cerebrum, cerebellum and brainstem indicated with red arrows.

The cerebrum has two halves (called hemispheres), and on each half there are four different main lobes.

Diagram showing left side of the brain with the frontal lobe (coloured blue) parietal lobe (coloured yellow), temporal lobe (coloured green) and occipital lobe (coloured red), indicated with red arrows.

The frontal lobes are easy to remember, as they are at the front!

Some know of their temples from tension headaches.

Tension headaches often entail tenderness, pain or throbbing around our temples - from the word temporal (temporal lobes).

Occipital and Parietal may be new words for some. Here is a way to remember how to say them.

For occipital, think of an Ox, sipping a tall drink!

occipital is pronounced ox-sip-i-tall

Parietal is a four syllable word, pa-ri-e-tal

  • pa - as in papa
  • ri - like in rice
  • e - small e, like in egg
  • tal - like tall

The outer layer of the cerebrum is called grey matter, as it is darker than the white matter underneath. This outer layer is known as the cortex, or or cerebral cortex. The term cortical means from or of the cerebral cortex.

So, the cortex is a part of the cerebrum (the outer layer).

Checklist:

Before you move on to the next level, please check:

  • You know what part of the brain the cerebrum is
  • You can name all four of the lobes and know where they are located
  • You know the difference between cortical (from cortex) and cerebral (from cerebrum)
