Document Summary
Participants: 5 healthy r-handed females subjects who identified a positive, personal memory about a perfume. Experimental odor (eo): 5 specific perfume identified by each subject. Experimental visual (ev): color photographs of experimental perfumes. Control visual (cv): color photographs of control perfume. Higher activation in the medial temporal lobe (amygdala, hippocampus, parahippocampal gyrus) and decreased activation in lingual gyrus, fusiform gyrus and middle occipital gyrus when presented with eo as compared to co/ev/cv. Increased activation in parahippocampual gyrus and amygdala and in thalamus and cerebellum in eo compared to co. Air puff is given if subject is at a resting state (not responding to stimuli/goal driven behaviors/not thinking about anything), but after the puff they might be thinking oh my, that chanel no. Subjective experience of an odor memory is more emotional than alternate sensations (visions) Emotional responses plotted on arousal vs valence, but in this study they only measure arousal.
