A study published in Nature in which researchers from the University of Valencia have participated has identified a neuron migration route that begins in the foetus around mid-gestation and continues until between two and three years of age. The route extends from the lateral ventricle, where these cells are born, to the entorhinal cortex, an area related to the regions where memory and learning are consolidated. There, neurons await signals that induce them to mature, providing plasticity to the brain after birth.

The Science group of journals publishes several parts of a high-resolution atlas of human brain cells, the largest 'map' of its kind to date. It is a series of papers from an international mega-project, the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative - Cell Census Network (BICCN), launched in 2017 to study brain cell types and their functions in humans, non-human primates and rodents. The data "will now allow researchers to address fundamental scientific questions about the human brain and its genetic organisation," states the introduction to the journal's special issue.
