Scientists Re- Evaluate Existing Brain Formation Idea




A recent research by a team of scientists has shed some light on the origin of the vertebrate brain. Through the current research, the scientists have challenged the existing facts about the formation process of the brain. As per the findings, the interpretation supported hitherto about the main regions formed at the beginning of vertebrate brain development is incorrect.

The scientists used the brain of an invertebrate organism, amphioxus (a fish-like marine chordate) for their research. As per the scientist, amphioxus, places in the evolutionary tree, is very close to the origin of the vertebrates. Additionally, the researchers have also created the first detailed map of the regions with the help of the obtained data.

The scientists said their work shows that the brain of vertebrates must have formed initially from two regions (anterior and posterior). The current study denied the fact that the vertebrates have formed from three regions (forebrain, midbrain and hindbrain).
