Localisation of Function Flashcards
What is the motor cortex responsible for?
Generation of voluntary motor movements
Where is the motor cortex located?
Frontal lobe
- Precentral gyrus
What does the somatosensory cortex detect?
Sensory events arising from different regions of the body
Where is the somatosensory cortex located?
Parietal lobe
What is the postcentral gyrus dedicated to?
The processing of sensory information related to touch
Where is the primary visual centre located in the brain?
Visual cortex in the occipital lobe
How does the somatosensory cortex produce sensations?
sensory information from the skin
What sensations do the somatosensory cortex produce?
- Touch
- Pressure
- Pain
- Temperature
Where does visual processing actually begin?
The retina
- Light enters and strikes the photoreceptors
- Nerve impulses from the retina are then transmitted to the brain via the optic nerve
Where might some of the nerve impulses from the retina travel to?
Areas of the brain involved in the coordination of circadian rhythms
Where do the rest of the impulses terminate?
Thalamus
What does the thalamus act as?
A relay station passing information on the visual cortex
What is the auditiry centre in the brain concerned with?
Hearing
Where does most of the auditory centre lie?
The temporal lobes
Where do auditory pathways begin?
Cochlea ( inner ear)
