Topographical mapping of grand-averaged ERPs under the cedarwood and resin conditions. The P1 components were elicited at the occipital region (Oz). P3b was predominantly recorded for the target stimuli at the parietal site (Pz) in both the cedarwood (A) and resin (B) huts. The latencies of the P1 and P3b components were almost the same regardless of the hut condition. Note that P1 was evoked at Oz, and P3b was recorded only for the target stimuli predominantly at Pz regardless of the hut condition
