| Outline of Final Research Achievements |
Patients having feeding/swallowing difficulty (dysphagia) have been increased with the advancement of an aging society. “Enjoy eating” is important not only for maintaining life but also for preserving quality of life and motivation for rehabilitation of dysphagia. The core of flavor is gustatory information and olfaction. However, it has been unclear how and where two kind of senses are integrated. To address this issue, we examined the spatiotemporal dynamics of excitatory propagation in cerebral cortex induced by simultaneous electrical stimulation of the chorda tympani nerve (CT) and main olfactory bulb (mOB). We performed in vivo optical imaging with a voltage sensitive dye. The primary sensory areas responded to each single stimulus. The simultaneous stimulation to mOB and CT increased the excitation in the AI, addition to response of each primary sensory cortices. This result suggest that partial of the gustatory and olfactory information was integrated in the AI.
