Localisation of function Flashcards
what is meant by Localisation of Brain Function?
Different areas of the brain have been linked to different functions/behaviour.
Which functions are to be localised to specific areas of the cortex ?
Language, Visual perception and Movement.
The idea that different parts of the brain perform different tasks means…?
that if a certain area is damaged (through injury/illness)= the functions associated will also be affected.
Where is the motor cortex and what is its specific function?
In the frontal lobes, controlling voluntary movement in the opposite side of the body.
Where is the Somatosensory cortex and the specfic function of it?
In the parietal lobes and tactile sensation.
Where is the Primary Visual Cortex and the specific function of it?
Occipital lobes and visual perception .
Where is the Secondary Visual Cortex and the specific function of it?
The Occipital lobes and surrounding areas, responsible for the perception of colour, form and movement.
Where is the Auditory cortex and the specific function of it?
Temporal lobes and to analyse speech based info (hearing).
Where is the Broca’s area and specific function?
Base of LEFT frontal lobe and speech production.
Where is the Wernicke’s area and the specific function?
Top of LEFT temporal lobe of Left hemisphere and Speech comprehension.
Consequences of damage to the Motor Cortex?
Loss of control over fine movements e.g not being able to draw/paint or tie shoelaces.
Consequences of damage to Somatosensory Cortex
Loss of sensation- inability to recognise objects by touch.
Consequences of damage to Primary Visual Cortex?
Cortical blindness.
Consequences of damage to Secondary Visual Cortex?
Inability to recognise things by sight.
Consequences of damage to Auditory Cortex?
Partial hearing loss (cortical deafness)
