Outline of Final Research Achievements |
Food deprivation or natural hunger produce a drive to seek and consume food. Cortical regulation of this motivation remains poorly understood. We used optogenetics to characterize functional importance of anatomical connection to and/or from insular cortex in mice. Several hypothalamic areas are known for its function to modulate eating behavior. Among all those areas Orexin neurons which are mainly located in lateral part of the hypothalamus has been implicated in not only food intake but also motivational aspect of eating behavior. We thus examined appetitive effect of orexin input to the insular cortex.
