Hemispheric Lateralisation AO3

• Left and Right Hemispheres

  • Have different specialisms
  • e.g. RH more active for global elements, LH more active for specific details
• Research has challenged the idea of functional specialisms
• Challenges to functional specialisms


  • JW able to learn to speak using the right hemisphere
  • Rats could still learn to navigate a maze with 10-50% of their cortex removed
• Lashleys Equipotentiality Theory


  No brain area is more important than another when navigating, brains work together holistically
