Abstract

Extracellular single unit recording during high fixed ratio bar press behavior, guided by multimodal cue stimuli for food intake, revealed functional heterogeneity in the monkey dorsolateral prefrontal cortex. Cells were found significantly more often in the ventral arcuate concavity, the dorsal arcuate concavity, the principal sulcal area and the inferior convexity which responded, respectively, to visual events, auditory events, visual plus auditory events and bar press.

摘要

在以多模态线索刺激引导食物摄入的高固定比率压杆行为期间进行的细胞外单单位记录显示，猴子背外侧前额叶皮层存在功能异质性。在腹侧弓形凹陷、背侧弓形凹陷、主沟区域和下凸区域发现细胞的频率明显更高，这些区域分别对视觉事件、听觉事件、视觉加听觉事件和压杆做出反应。
