Definition of Hemispheric Lateralisation
Definition of Hemispheric Lateralisation
Concept
- Hemispheric lateralisation refers to the idea that the two halves of the brain are not exactly alike.
- Each hemisphere specialises in different functions and processes certain types of information more efficiently.
Left Hemisphere
- Typically associated with language skills such as speaking and writing.
- Responsible for analytic thought, logical reasoning, and problem-solving.
- Controls movements on the right side of the body.
Right Hemisphere
- Known for its involvement in spatial abilities and creativity.
- Processes holistic thought, intuition, and visual imagery.
- Governs movements on the left side of the body.
Interhemispheric Communication
- The corpus callosum is a band of fibres connecting the two hemispheres, allowing for the exchange of information.
- Efficient information processing often requires the cooperation of both hemispheres.
Significance
- Understanding hemispheric lateralisation helps in identifying how specific brain areas are related to functions and behaviours.
- Research in this area contributes to insights about neurological disorders and potential treatments.
