･A correlation between balance function and the volume of the hippocampus and subfields was found in healthy elderly subjects.
･The balance function may be involved in the volume of the whole hippocampus and specific subfields. The index of postural stability (IPS) closed eyes/soft surface condition is considered to reflect vestibular function.
･Thus, IPS may be useful in evaluations of the relationship between the vestibular system function via the hippocampus and balance.
