Development
During human
cornu ammonis. After about 18 weeks, the walls of the fissure fold into each other and begin to fuse. By 30 weeks, the hippocampal sulcus is normally obliterated except for its most medial part, leaving a shallow surface indentation.[1]
Clinical significance
Enlargement of the hippocampal sulcus has been associated with medial temporal lobe atrophy occurring in Alzheimer's disease.[2]
