Here, we defined the rostral junction point of the genu of the corpus callosum (GCCrj) that refers to the central convergence point of bilateral genu of the corpus callosum structures at the rostral part on coronal histological slices. The GCCrj and rostral junction point of the habenular commissure (HBCrj) constituted the new GCCrj\u2010HBCrj (GH) coordinate plane, which is located at the midline of the cerebral hemispheres. We described and delineated the GCCrj and HBCrj reference points across mouse, rat and tree shrew brains. We performed conversions between the GH points and the points of the existing BL and AP coordinate systems in standard brain atlases for each species. The height values for the GH system's G and H points were \u22120.55, +0.15 and \u22120.05\u2009mm across the three species, respectively. The horizontal plane of the GH system showed superior agreement with the horizontal plane of the BL coordinate system compared to that of the AP system within existing atlases. In summary, this study provides the spatial coordinates of the GCCrj and HBCrj as new reference coordinates for a multi\u2010species brain atlas. The two landmarks GCCrj and HBCrj are positioned on both the horizontal plane and cerebral mid\u2010sagittal vertical plane, running parallel to the BL reference plane. The novel GH coordinate system is compatible with established standard stereotaxic brain coordinate systems and may provide an alternative for a mammalian brain coordinate atlas.<\/jats:p>","DOI":"10.1111\/ahe.70171","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T05:34:36Z","timestamp":1787808876000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spatial Coordinates of the Rostral Junction Points of the Genu of the Corpus Callosum and the Habenular Commissure in Tree Shrew, Mouse and Rat Brains: A Preliminary Study"],"prefix":"10.1111","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7421-136X","authenticated-orcid":false,"given":"Rong\u2010Jun","family":"Ni","sequence":"first","affiliation":[{"name":"Mental Health Center and Institute of Psychiatry, National Center for Mental Disorders West China Hospital, Sichuan University  Chengdu China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,26]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyt.2021.699416"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/brainsci16050490"},{"key":"e_1_2_10_4_1","volume-title":"The Mouse Brain in Stereotaxic Coordinates, Compact: The Coronal Plates and Diagrams","author":"Franklin K.
