hemispheric localisation of the cerebrum

frontal lobe

• at front

• personality

• motor cortex

• movement and speech

temporal

• temples

• hearing sometimes memory

parietal

• top and back

• senses like touch and temperaure (somato)

occipital

• back of the head

• vision

primary visual cortex

• light levels

• wavelength (colour)

• 2d image

• within the occipital lobe

visual association area

• understands and interprets information using visual memory

• within the occipital lobe

primary auditorty cortex

• detects amplitude and wavelength

• l to r and r to l

• tonotopically organised

• lowest freq at the front and highest at the back

auditory association area

• understanding and interpreting the sound

• loud sound=scary

carl wernicke (1874)

• paitient=receptive aphasia

• couldnt understand language

• autopsy discovered damage to the left auditory association area

• wernickes ares=left temporal lobe that processes langauge in the auditory association area

paul broca (1861)

• paitient only said “tan”

• expressive aphasia

• autopsy showed damage to brocas area

• left motor cortex in the left frontal lobe

motor cortex

• somatopically organised

• more fine motor control, more of the motor cortex is dedicated

• r to l and l to r

sensory cortex

• somatopically organised

• more sensory info, more sensory cortex dedicated

• r to l and l to r
