localisation of function Flashcards
What does localisation of function refer to?
The theory that different areas of the brain are responsible for different behaviours, processes, or activities.
What was the holistic theory in relation to brain function?
The idea that the whole brain was involved in processing thought and action.
Who were the scientists that contributed to the shift from holistic theory to localisation of function?
Broca and Wernicke.
In what decade did the belief in localisation of function gain support?
The 1880s.
How many lobes is the brain split into?
Four lobes.
What are the names of the brain lobes?
- Frontal Lobe
- Parietal Lobe
- Occipital Lobe
- Temporal Lobe
Fill in the blank: The Frontal Lobe, Parietal Lobe, Occipital Lobe, and _______ are the four lobes of the brain.
[Temporal Lobe]
True or False: The localisation of function theory suggests that all parts of the brain are equally involved in all functions.
False
What lobe is the motor area in?
frontal
What is the function of the motor area?
-Controls voluntary movement in opposite sides of the body
What hemisphere is the motor area in?
Both
What are the consequences of damage to the motor area?
Loss of control over fine motor movements
What lobe is the somatosensory area in?
Parietal Lobe
What is the function of the somatosensory area?
Where sensory information from the skin is processed
What hemisphere is the somatosensory area in?
Both
What are the consequences of damage to the somatosensory area?
Numbness/ pins and needles, won’t feel hot or cold in the area.
What lobe is the visual area in?
Occipital
What is the function of the visual area?
Each eye sends info from the Right Visual Field to the left cortex and from the Left Visual Field to the right cortex
What hemisphere is the visual area in?
Both
What are the consequences of damage to the visual area?
Damage to left hemisphere can cause damage to the RVF and damage to the right hemisphere can cause damage to the LVF
What lobe is the auditory area in?
temporal
What is the function of the auditory area?
-Analyses and processes acoustic information
What hemisphere is the auditory area in?
Both
What are the consequences of damage to the auditory area?
Partial hearing loss, the more extensive the damage the more extensive the loss.
