Within the P3 latency range, females showed neuronal activity in response to both body odors above central brain areas. Additional medial frontal activation predominantly occurred in response to the anxiety signals. Recently, it was demonstrated by CSD analysis that neuronal activity located in medial frontal brain areas is most prominent in the P3 latency window and in response to potentially harmful odors [41]. In general, medial prefrontal activation is the most common observation in emotional activation studies [42] and may be related to flexible physiological adjustments in (socially) relevant situations [43], as well as to the integration of sensory and cognitive information in order to adjust physiological activity [44].
