brain anatomy

Notes from CBMM 2022 summer course. I haven't double checked these

• language areas found in frontal and temporal lobes
  • unilateral. localized on left side of the brain
• temporal lobe
  • audio processing
  • audio cortex
• and then wernicke's area
  • pitch
• and then broca's area: angular gyrus
  • language processing
• motor cortex
  • first area of the brain to be mapped out
  • movement
  • at boundary between frontal and parietal lobe on the frontal side
• somatosensory lobe
  • right behind the frontal lobe
  • senses
  • parts of the body that are more sensitive are over-represented in somatosensory cortex
• occipital lobe
  • fovia over-represented vs periphery of vision
    • discovered from studies of patients with damage to occipital lobe
• hippocampus
  • memory area lies deep in the temporal lobe
  • HM experiments
  • essential role in building memories
• thalamus
  • role under active research
  • at first: researchers thought was relay station connecting periphery and cortex
  • now: think it serves some gating function. some inhibitory function
  • when we sleep, TRN enters different activity mode
