      The brain can be divided down the middle lengthwise into two halves called the cerebral hemispheres. Each cerebral hemisphere is divided into four lobes by sulci and gyri. The sulci (or fissures) are the grooves and the gyri are the “bumps” that can be seen on the surface of the brain.

      The frontal lobe is the bit at the front (behind your forehead) and is concerned with reasoning, planning, parts of speech and movement (motor cortex), emotions, and problem-solving. The parietal lobe is behind the central sulcus (think of the bit of your head where your crown is!) and perceives things in our environment, such as touch, pressure, temperature and pain. The temporal lobe sits underneath the frontal and parietal lobe (think of your temples – behind there!). It deals with all the noise that we process and handles our memory (in the hippocampus). The last lobe is the occipital lobe, which is at the back of your head (think of the bump at the back!) and mostly deals with our vision
