Ancient gene found to regulate brain folding, scientists report
Researchers report that an ancient gene, not a newly evolved one as previously thought, regulates the folding of the brain.
What happened
Scientists reported that an ancient gene regulates the process of brain folding, which produces the wrinkles and grooves seen in the brain.23
This challenges the traditional view that brain folding results from newly evolved genes.2
Separately, Taiwan's National Health Research Institutes reported finding genes linked to early-onset schizophrenia.1
Key points
What the coverage leaves out
- None of the outlets reviewed named the specific gene identified or the research institution and journal involved.
- None of the outlets reviewed described the study methodology, such as the species or models used.
- It is unclear from the coverage reviewed whether the Taipei Times report on genes linked to early-onset schizophrenia refers to the same research as the brain-folding findings described by the other outlets.
Why it matters
Brain wrinkles and grooves are linked to advanced cognition, and understanding the genetic mechanisms behind their formation could inform research into brain development.2
