AO1

• lateralisation: two halves of the brain are functionally different and certain mental processes and behaviours are mainly controlled by one hemisphere rather than the other
• for language the two main centres are only in the LH. The RH can only produce rudimentary words and phrases but contributes emotional context to what is being said
• vision is not lateralised, motor and somatosensory areas appear in both hemispheres
• for the motor area the brain is cross wired- The RH controls movement on the left side of the body whilst the LH controls movement on the right
• vision is both contralateral and ipsilateral (opposite and same sided). each eye receives light from the LVF and the RVF
• The LVF of both eyes is connected to the LH. This enables the visual areas to compare the slightly different perspective from each eye and aids depth perception
