6.6.1 Hemispheric Lateralisation

• What does hemispheric lateralisation refer to?

  Specialisation of brain functions
• Hemispheric lateralisation involves the specialisation of functions in the brain’s two hemispheres—the left and the right
• Both brain hemispheres are identical in their functions.

  False
• Match the hemisphere with its primary function:

  Left ↔️ Speech production, comprehension

  Right ↔️ Visual-spatial perception, facial recognition
• Which hemisphere controls speech production and comprehension?

  Left
• Mathematical computation is primarily controlled by the left hemisphere
• Hemispheric lateralisation allows the brain to perform diverse tasks efficiently.
• What is the corpus callosum's role in the brain?

  Interhemispheric communication
• Key functions lateralised to the left hemisphere include language and mathematical computation
• The left hemisphere is primarily responsible for tasks requiring logical and analytical processing.
• Which hemisphere is specialised for facial recognition?

  Right
• The right hemisphere is crucial for tasks requiring spatial, emotional, and visual analysis
• The corpus callosum allows the left and right hemispheres to communicate with each other.
• What are two key functions of the left hemisphere?

  Language, mathematical computation
• Language processing in the left hemisphere relies on Broca's and Wernicke's areas
• The right hemisphere is specialized for processing emotions and recognizing faces.
• What is the primary function of the corpus callosum?

  Interhemispheric communication
• The corpus callosum facilitates sensory integration by combining information from both hemispheres
• Hemispheric lateralisation improves task efficiency by reducing cognitive load.
• What is one potential downside of hemispheric lateralisation?

  Impaired interhemispheric communication
• The left hemisphere excels in language and mathematical computation
• The right hemisphere enhances visual and emotional perception.
