Editing Cerebral cortex (section)

====Layer IV====
Layer IV, the '''[[internal granular layer]]''', contains different types of [[stellate cell|stellate]] and pyramidal cells, and is the main target of [[thalamocortical radiations|thalamocortical afferents]] from thalamus type C neurons (core-type)<ref name="Jones"/> as well as intra-hemispheric corticocortical afferents. The layers above layer IV are also referred to as supragranular layers (layers I-III), whereas the layers below are referred to as infragranular layers (layers V and VI). [[African elephant|African elephants]], [[Cetacea|cetaceans]], and [[hippopotamus]] do not have a layer IV with axons which would terminate there going instead to the inner part of layer III.<ref name="u035">{{cite journal | vauthors = Bhagwandin A, Molnár Z, Bertelsen MF, Karlsson KÆ, Alagaili AN, Bennett NC, Hof PR, Kaswera-Kyamakya C, Gilissen E, Jayakumar J, Manger PR | title = Where Do Core Thalamocortical Axons Terminate in Mammalian Neocortex When There Is No Cytoarchitecturally Distinct Layer 4? | journal = The Journal of Comparative Neurology | volume = 532 | issue = 7 | pages = e25652 | date = July 2024 | pmid = 38962882 | doi = 10.1002/cne.25652 }}</ref>
