Corpus callosum parts (mnemonic)

Last revised by Daniel J Bell on 16 Feb 2019

A useful mnemonic to help remember the parts of the corpus callosum, from anterior to posterior, is:

  • Remember Genu Before Splenium
  • Remember G Before S (as G comes before S alphabetically)


  • R: rostrum
  • G: genu
  • B: body (trunk)
  • S: splenium
