lateralisation

• The main part of the brain (the cerebrum) is divided into two symmetrical halves called the left and right hemisphere.
• lateralisation is when our physical and psychological functions are controlled or dominated by a particular hemisphere
• left hemisphere controls the right side of the body
• right hemisphere controls the left side of the body
• Language is linked to the left hemisphere.
• The cerebral cortex is the outer layer of both hemisphere
• Each eye sends information from the right visual field to the left visual cortex and from the left visual field to the right visual cortex. This means that damage to the left hemisphere, for example, can produce blindness in part of the right visual field of both eyes.
