New view of brain development: Striking differences between adult and newborn mouse brain
4 months ago Comments Off on New view of brain development: Striking differences between adult and newborn mouse brain
Spikes in neuronal activity in young mice do not spur corresponding boosts in blood flow — a discovery that stands in stark contrast to the adult mouse brain. This new study raises questions about how the growing human brain meets its energy needs, as well as how best to track brain development with fMRI, which relies on blood-flow changes to map neuronal activity. The research could also provide critical insights for improving care for infants.
