Fig. 2From: Effects of volatile sesquiterpenes from Japanese cedarwood on visual processing in the human brain: an event-related potential studyRepresentative examples of the sinusoidal grating stimuli and the time sequence of the task. A 10° angular sinusoidal grating was presented as the frequent stimulus (F) at a 60% probability. A 5° angular infrequent (I) stimulus and a 0° angular target (T) stimulus were each presented at 20% probabilityBack to article page
