The　prefrontal　cortex　is　crucial　for　memory　encoding　and　processing,　in　which　the　lateral　prefrontal　cortex　(LPFC)　is　more　involved　in　semantic　and　episodic　memory,　whereas　the　medial　prefrontal　cortex　(MPFC)　is　more　related　to　the　associative　information　processing　and　social　cognition.　Social　statistical　information　is　a　kind　of　typical　associative　information　with　sociality.　However,　the　role　of　the　prefrontal　cortex　in　comprehending　the　social　statistical　information　remains　unknown　yet.　This　study　focused　on　the　brain　activities　of　36　normal　subjects　in　the　prefrontal　cortex　using　fMRI　while　they　viewed　the　social　statistical　information　presented　in　either　visual　form　as　a　graph　or　textual　form　as　a　verbal　description　of　the　information　in　the　graph.　The　results　showed　that　the　graph　and　textual　tasks　consistently　activated　the　anterior　and　posterior　portions　of　ventrolateral　prefrontal　cortex　(VLPFC),　the　dorsal　and　ventral　MPFC.　The　results　suggest　that　the　VLPFC　and　the　MPFC　commonly　contribute　to　the　social　statistical　information　processing.　©　Springer　International　Publishing　2013.
