Document Summary

Cerebral cortex: very large in humans, divided into two identical halves, halves left hemisphere and right hemisphere, both sides have the same lobes, divided into different areas or lobes which have different functions. Three functional divisions: primary sensory areas: thalamus, association cortex: associated with usually sensory areas. They combine sensory information and make sense of them. Least well understood: primary motor area (smallest part) : If you see something information goes from: eye thalamus occipital lobe. Information from the left visual field (not the left eye) goes to the right occipital lobe of the brain and vice versa. The representation of the somatosensory cortex in the brain depends on the amount of sensory fibres. Motor cortex is at the very back of the frontal lobe. Output: motor cortex left hemisphere sectio(cid:374) (cid:272)o(cid:374)trols the (cid:271)od(cid:455)"s right side.

Connections between primary sensory/motor cortex and body are contralateral:
