Short answer
Several possible studiesNo clear answer.
More than one paper fits the article's details, and none fits well enough to single out. Checking claims against the wrong study would be worse than not checking them at all.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim 1 of 5Not checkedNew research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years.View evidenceHide evidence
As statedtwo distinct organs
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 2 of 5Not checkedThe discovery overturns a prevailing model of brain development in which a single progenitor cell early in development gives rise to the entire brain.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 3 of 5Not checkedThe front of the brain arises from a different progenitor cell than the back of the brain, and the forebrain/midbrain and hindbrain follow separate developmental paths from the earliest embryonic stages.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 4 of 5Not checkedResearchers successfully coaxed human pluripotent stem cells to become functional hindbrain motor neurons in the laboratory.View evidenceHide evidence
As statedfor the first time
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 5 of 5Not checkedThe findings may open new avenues for studying diseases that affect the brain stem, including spinal muscular atrophy and ALS.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Method layer
No single source study was found.
NewsLink still surfaces nearby research so you can inspect the field instead of a single paper.
