localisation of function Flashcards
definition of localisation of function
the theory that different areas of the brain are solely responsible for different behaviours, processes or activities
frontal lobe
location of awareness
part of our consciousness
decision making
occipital lobe
visual information
-stimuli
cerebellum lobe
balance
temporal lobe
sound language and memories
auditory area - wernicks area
located in the temporal lobe in both sides of the brain
- recognise and responds to sound memory etc
- centre for comprehension and understanding
visual centre
in the occiptal lobe detecting and patterns and processing
somato sensory area
parietal lobe
-sensory and sensation
motor area
controls muscles via spinal chord
-situated in the frontal lobe of both hemispheres
brocas area
frontal lobe
-responsible for speech production
limitation of localisation of function 1
when the brain has been damaged eg through illness or accident, and a particular function has been compromised or lost, the rest of the brain appears to reorganize itself in an attempt to recover the function.
- so other partd are able to adapt NO LOCALISE
limitation of localisation of function 2
higher cognitive functions are distributed holistically .
- karl lashley 1950
- suggests that higher order cog functions eg processes in learning are not localised but distributed in an holistic way.
- learning is too complex to localise
strength of localisation of function 1
person et al 1998 used brain scans to demonstrate how wernicks area was active during listening tasks and brocas in learning .
- YES diff areas are localised
strength of localisation of function 2
case study support
- phineas gage
- his temporal lobe was damaged
- areas associated with these were affected such as personality
- so lobes are localised for certain functions
