In order to investigate the effects of visual recognition of indoor plants on psychophysiology, human brain electroencephalography (EEG) was measured while subjects were watching Pachira aquatica (RPA), Ficus benjamina 'Star Light' (RFS) placed in the room, or objects composed of desk, cabinet, and computer in the room as a control group (CON). It has been shown that the groups of VPA and RFS showed significantly decreased delta wave in the frontal lobe and temporal lobe regions as compared to that of CON, indication that the activity of brain function may be enhanced in those area. It was, therefore, postulated by these results that indoor plants could activate the function of the frontal lobe which is the center of thougth and the comprehinsive brain function and takes charge of organization of the brain function, and the temporal lobe which plays important roles in the regulation of language, memory, and emotion.
