| Research Abstract |
The present project aimed to evaluate food texture by means of neuroscientific techniques. The influence of food texture on the mouse brain was surveyed. Powdered food, in which mice can take using tongue but not teeth, resulted in the increase of hippocampal and diencephalon BDNF levels. However, this increase was not detected under hard(control) and soft food intake conditions. These results suggest that stimulation of the oral cavity through teeth is important to sustain ordinal brain functions regardless of hard or soft food texture. Increase of BDNF may be one of brain reactions against the stress caused by non-utilization of teeth.
