Advanced Imaging Shows Crescendo, Diminuendo of Brain Circuitry

Using newly developed imaging techniques, neuroscientists for the first time have “unfolded” the brain’s sea-horse-shaped hippocampus to reveal how dynamic activity within the brain structure’s complex architecture orchestrates memory formation. Details appear in the Jan. 24 edition of the peer-reviewed journal Science. The researchers used extremely high-resolution functional magnetic resonance imaging (fMRI) and software developed at UCLA’s Ahmanson-Lovelace Brain Mapping Center to study blood flow within the hippocampus as 10 human volunteers learned to associate names with faces.
