Localisation Of The Brain Flashcards
What is the concept of localisation of function in the brain?
The idea that different parts of the brain perform different tasks and are involved with different parts of the body.
Who were the key scientists that supported the idea of localisation of function?
Paul Broca and Karl Wernicke.
What happens if a certain area of the brain becomes damaged?
The function associated with that area will also be affected.
What are the two symmetrical halves of the brain called?
Left hemisphere and right hemisphere.
What is lateralisation in the context of brain function?
The concept that some functions are controlled or dominated by a particular hemisphere.
Which hemisphere is generally associated with language in most people?
The left hemisphere.
What are the four lobes of the brain?
- Frontal lobe
- Parietal lobe
- Occipital lobe
- Temporal lobe
What is the motor area and where is it located?
The motor area is located at the back of the frontal lobe and controls voluntary movement in the opposite side of the body.
What does the somatosensory area represent?
Sensory information from the skin, such as touch, heat, and pressure.
What is the significance of the central sulcus?
It separates the motor area from the somatosensory area.
Where is the visual area located in the brain?
In the occipital lobe at the back of the brain.
What occurs if the left hemisphere is damaged in relation to vision?
It can produce blindness in part of the right visual field of both eyes.
What is the function of the auditory area?
It analyses speech-based information.
What is Broca’s area responsible for?
Speech production.
What condition results from damage to Broca’s area?
Broca’s aphasia.
What characterizes Broca’s aphasia?
Speech that is slow, laborious, and lacking in fluency.
What is Wernicke’s area responsible for?
Language understanding.
What condition results from damage to Wernicke’s area?
Wernicke’s aphasia.
What characterizes Wernicke’s aphasia?
Fluent but meaningless speech, often with nonsense words.
Fill in the blank: Damage to the left hemisphere can produce blindness in part of the _______.
right visual field.
True or False: Language areas are found in both hemispheres of the brain in most people.
False.
