Localisation Of Function Flashcards
Holistic theory
Brain works as one organ
Localisation theory
Different areas of the brain are responsible for different functions
Where is the motor cortex
Frontal lobe
What does the motor cortex do
Control voluntary movements
Consequence of damage to the motor cortex
Loss of control over movements in hands/ fingers
Where is the somatosensory cortex
Parietal lobe
What does the somatosensory cortex do
Processes sensory info from the skin
Signals spinal cord
Reach thalamus
Then somatosensory
Then response
What is the consequence of damage to somatosensory
Less or more pain sensitivity
Where is the visual cortex
Occipital lobe
What does the visual cortex do
Receives/ processes visual info
Consequence of damage to visual cortex
Blindness/ poor vision
Where is the auditory cortex
Temporal lobe
What does the auditory cortex do
Analyses speech
Consequence of damage to auditory cortex
Hearing loss
Where is Broca’s area
Frontal lobe ( left only)
What does Broca’s area do
Speech production
Consequence of damage to Broca’s area
Brocas asphasia
Difficulty speaking
Where is wernickes area
Temporal lobe
(Left only)
What does wernickes area do
Responsible for language comprehension
Consequence of damage to wernickes area
Wernickes asphasia
Inability to understand language
Evaluate localisation of function
+ evidence from brain scans- Petersen found wernickes area active during listening- objective
- simplistic- EB had left hemisphere removed but regained language ability- more than one area
- contradiction- Lashley- up to 50% of cortex in rats removed- still able to learn maze- holism
- gender differences- women have larger wernickes- greater use of language
+case study- phineas gage- changed personality- suggests frontal lobe regulates mood
