Map formation in the brain

• Topographic maps omnipresent in the sensory regions of the brain

  • retinotopic maps: neurons ordered as the locations of their visual field on the retina
  • tonotopic maps: neurons ordered according to tone for which they are sensitive
  • maps in somatosensory cortex: neurons ordered according to body part for which they are sensitive
  • maps in motor cortex: neurons ordered according to muscles they control
