Ber at doses of 1-4 mg·〓 iv was shown to decrease dose-dependently the spectrum power of delta dominant frequency in cortical area and transfer the dominant freqency from delta to theta rhythm in hippocampus. Under the same conditions, the effects of physostigmine 0.1mg·〓 iv on EEG were similar to Ber.
Ber 〓能浓度依赖性地使清醒兔皮层区EEG持续出现低振幅快波，其主频率功率明显减少，并使海马区EEG出现持续且有规律的θ节律，Ber 〓iv使功率谱中δ、θ、α+β相对功率由对照组的43.1±9.3、28.0±4.0和26.1±6.3分别变为28.3±4.7、48.6±5.8（P.01）和22.6±7.2，海马区主频率从δ段右移至θ段，主频率功率明显减少。

In particular, it is unknown how the relevant neural substrates function as a network to mediate perspective-taking during the task requiring understanding other's belief. The current work first developed a new psychological paradigm that excludes potential confounds such as the processing of language, biological motion, episodic memory and causal coherence in the paradigms used in previous studies. I recorded neural activities associated with mental inference task using functional magnetic resonance imaging and electroencephalography in order to investigate the functional roles of several brain areas (i.e. precuneus, MPFC, etc.) that engage in understanding other's belief. I also proposed a computational model based on the neuroimaging results that simulated the neurocognitive mechanism underlying cortical dynamics in correct judgment of other's belief.
本文首先发展了一个新的心理学实验范式，排除以往常用&错误信念&范式中与语言加工、生物运动、情景记忆及事件连续性和因果性等方面的混淆，采用功能磁共振成像（functional magnetic resonance imaging， fMRI）和脑电（Electroencephalography， EEG）时频分析等脑成像技术，记录与理解他人信念任务相关的神经活动，通过对行为和脑成像数据的分析，研究楔前叶和内侧前额叶等脑区在理解他人信念任务中的功能意义，并根据脑成像结果，提出一个基于自我和他人视角竞争的计算模型，模拟大脑在理解他人信念时做出正确决策时的认知神经机制。

The fMRI studies showed that,(1) when information obtained from self-perspective covered the information obtained from other-perspective, compared to a deductive reasoning task, the mental inference task induced increased neural activity in precuneus, decreased neural activity in ventral MPFC and enhanced functional connectivity between these two brain areas;(2) this neural activity pattern was observed in understanding human's belief, but not in understanding artificial intelligence;(3) when information obtained from other-perspective covered the information obtained from self-perspective, the mental inference task induced additional increased neural activity in dorsal MPFC and the right frontal cortex, as well as enhanced functional connectivity between these two cortical areas in addition.
EEG实验发现，额叶alpha频段神经活动在信念理解任务的早期（400-800 ms）表现为去同步化，顶叶alpha频段神经活动在信念理解任务的较晚时程（600-1000 ms）则表现为同步化。
