GoKawiilStudy on brain segmentation misreported as evidence of 'two brains'
A new developmental biology paper examining how the vertebrate nervous system forms its major segments—forebrain, midbrain, hindbrain and spinal cord—was mischaracterized in press coverage as showing humans have two brains. The confusion originated from a university press release, and the underlying research actually explores how the embryo's ectoderm gives rise to distinct neural segments during development.
