Thirty-second average and overall mean oxyhemoglobin (oxy-Hb) concentration in left prefrontal cortex while touching hinoki or marble materials. a Changes in each 30-s average oxy-Hb concentration over 90 s. b Overall mean oxy-Hb concentration. Data are expressed as means ± standard error, n = 22, p < 0.05 (comparing pre- vs. postmeasurement value), *p < 0.05 (comparing hinoki vs. marble materials) as determined by the paired t test (one-sided); the Holm correction was applied
