I recorded simultaneously the single unit activity from are 36 and the local field potential from area TE of monkey inferior temporal cortex when the monkey performed visual memory task and then analyzed the mnemonic information between these areas. Coherence analysis in a frequency domain reveals that there was a coherent activity in beta frequency during the delay period. This beta coherent activity was selective to the cue stimulus. Causality analysis of the local field potential between area 36 and area TE showed that, during the delay period, mnemonic signal in beta frequency flows from area 36 to area TE.

同时记录了猴进行视觉记忆任务时下颞叶皮层36区的单位活动和TE区的局部场电位，分析了这两个区域之间的记忆信息。频域相干性分析表明，在延迟期间，β频率存在相干活动。这种β相干活动对线索刺激具有选择性。对36区和TE区之间的局部场电位的因果关系分析表明，在延迟期内，β频率的记忆信号从36区流向TE区。
