Hemispheric lateralisation

• What is hemispheric lateralisation?

  There are two sides of the brain
• For some functions the localised areas appear in both hemispheres
• What is an example of a function where the localised areas appear in both hemispheres?

  Vision - visual area in left and right occipital lobe
• Which hemisphere are the two main centres for language found?

  Left
• Why can we say language is lateralised?

  Performed in the left side of the brain
• What is the left hemisphere referred to as in terms of language?

  The analyser
• What is the right hemisphere referred to as in terms of language?

  The synthesiser
• What can the right hemisphere only produce in terms of language?

  Rudimentary words/phrases but provides emotional context
• What areas are not lateralised?

  Vision, motor, somatosensory
• In terms of the motor area, what is the brain?

  Cross-wired (contralateral wiring)
• What does it mean that, in terms of the motor area, the brain is cross-wired (contralateral wiring)?

  Right hemisphere controls movement on the left side of the body and the left hemisphere controls movement on the right side
• In terms of the vision area, what is the brain?

  Both contralateral and ipsilateral
• What does it mean if the brain is ipsilaterally wired?

  Same-sided
