Gingulate Gyrus

   

  • Lies between corpus callosum and cingulated sulcus

  • Cingulate cortex overlies the cingulum, the largest association bundle

  • The part posterior to splenium of corpus callosum is called isthmus of cingulate gyrus

  • Beyond isthmus, it imperceptibly becomes parahippocampal gyrus

  • Receives blood supply from cingulated branches of anterior cerebral and pericallossal arteries

  • Main function is limbic

Paracentral Lobule  

 
  • Sorrounds the medial end of the central sulcus

  • Abuts on the falx cerebri

  • Lodges sensory and motor functions of the lower limb

  • Supplied by anterior cerebral artery

  • Damage to it causes paraplegia
