Hemispheric Lateralisation Flashcards
The idea of hemispheric lateralisation is that…
The left and right hemispheres of the brain are responsible for different functions
The two hemispheres have different…
Functions and roles
The left hemisphere receives information and controls which side?
The right visual field
The right hemisphere receives information and controls which side of the body?
The left side of the body
What does the left hemisphere control?
Speech, language and comprehension.
Analysis and calculations
Time and sequencing
Recognition of words, letters and numbers
What does the right hemisphere control?
Creativity
Spatial ability
Context/ perception
Recognition of faces, places and objects
The left hemisphere is responsible for what and why?
Language as the two main areas are the Broca’s and Wernicke’s area
What is Broca’s area responsible for?
Speech production
What is Wernicke’s area responsible for?
The understanding of language
Where are Broca’s and Wernicke’s area located?
The left hemisphere
What is the right hemisphere responsible for?
Recognition of faces, places, objects and creativity
What can the right hemisphere only produce but what does it contribute towards
Only produce rudimentary words and phrases but contributed to the emotional context of what is being said
What is the corpus callosum?
A bundle of nerves in the brain that enables corresponding regions of the left and right hemispheres to communicate
Many functions are not lateralised such as…
Vision, motor and somatosensory area
Why are vision, motor and somatosensory areas not specialised?
As they occur in both hemispheres
