| Research Abstract |
We studied cortical activity of food cognition using magnetoencephalography and tractgraphy.
Neuromagnetic activities in 14 healthy female volunteers (24-35 years old, all right-handed) were recorded while fasting. Four types of visual stimuli-food picture, non-food picture, food name, and non-food name--were presented in random order. Subjects were instructed to judge whether items were food or non-food immediately after presentation and think nothing after judgment. Cerebral activities were evaluated by visual inspection of the topographies.
Food items resulted in higher activity of beta band in the left around posterior parts of superior temporal gyrus, than did non-food items.
Visual stimulation with food judge is possibility to relate Wernicke area.
