食物奖赏和渴求行为相关的大鼠左侧眶额叶皮质Delta频段脑电活动OA北大核心CSCDCSTPCD
Delta EEG Activity in Left Orbitofrontal Cortex in Rats Related to Food Reward and Craving
眶额叶皮质与中脑边缘多巴胺奖赏系统有着复杂的相互纤维联系.先前的研究探讨了药物成瘾过程中眶额叶皮质的脑电活动.在本实验中,将探讨食物奖赏和渴求过程中该皮质的脑电活动.实验采用了两个环境:对照环境和食物刺激相关的环境.首先,训练大鼠在食物刺激相关的环境中吃巧克力花生豆,而后在该环境中设置两种不同的刺激方式:能看到和闻到但不能吃到(渴求实验),或者仍旧可以吃到巧克力花生豆(奖赏实验):同时进行左侧眶额叶皮质的脑电记录.结果发现,在食物刺激相关的环境中…查看全部>>
The orbitofrontal cortex (OFC) is particularly important for the neural representation of reward value. Previous studies indicated that electroencephalogram (EEG) activity in the OFC was involved in drug administration and withdrawal. The present study investigated EEG activity in the OFC in rats during the development of food reward and craving. Two environments were used separately for control and food-related EEG recordings. In the food-related environmen…查看全部>>
