The anterior cingulate cortex, like other prefrontal regions, undergoes a prolonged developmental process relative to sensorimotor regions. Pasko Rakic, JeanPierre Bourgeois, and others at Yale University have shown that, even though neurogenesis is completed in the anterior cingulate cortex (area 24) before the visual cortex, synaptogenesis occurs later. Synaptic density in area 24 then remains at a high level until sexual maturity. Speculations relating the development of this brain region to behavior have been proposed by Michael Posner and Mary Rothbart of the University of Oregon on the basis of behavioral data from infants and children on tasks thought to require the anterior cingulate cortex. B. J. Casey at the Sackler Institute in New York and colleagues have used MRI-based morphometric studies of this region to relate its size and symmetry to behavioral development. More recently, Casey has used functional MRI studies for this purpose.
