Fig. 2From: Correction to: Comparison of the effects of olfactory stimulation by air-dried and high-temperature-dried wood chips of hinoki cypress (Chamaecyparis obtusa) on prefrontal cortex activityTime-dependent oxy-Hb concentration changes (per second) in the prefrontal cortex during olfactory stimulation by air-dried or high-temperature-dried hinoki cypress wood chips. The oxy-Hb concentration shown is the difference between the pre- and postmeasurement conditions. Data are expressed as mean ± SE; n = 19Back to article page
