Many studies have reported that the DLPFC can be activated during the processing of emotional information in tasks requiring working memory. However, it is still not clear whether modulating the activity of the DLPFC influences emotional perception in a detection task. In the present study, using transcranial direct-current stimulation （tDCS）, we investigated （I） whether modulating the right DLPFC influences emotional face processing in a detection task, and （2） whether the DLPFC plays equal roles in processing positive and negative emotional faces. The results showed that anodal tDCS over the right DLPFC specifically facilitated the perception of positive faces, but did not influence the processing of negative faces. In addition, anodal tDCS over the right primary visual cortex enhanced performance in the detection task regardless of emotional valence. Our findings suggest, for the first time,that modulating the right DLPFC influences emotional face perception, especially faces showing positive emotion.展开更多

Using psychophysiological interaction and dynamic causal modeling analyses, we investigated the functional interactions between regions involved in the decision- making process while participants performed temporal discounting tasks in both the gains and losses domains. We found two distinct intrinsic valuation systems underlying temporal discounting in the gains and losses domains： gains were specifically evaluated in the medial regions, including the medial prefrontal and orbitofrontal cortices, and losses were evaluated in the lateral dorsolateral prefrontal cortex. In addition, immediate reward or pun- ishment was found to modulate the functional interactions between the dorsolateral prefrontal cortex and distinct regions in both the gains and losses domains： in the gains domain, the mesolimbic regions; in the losses domain, the medial prefrontal cortex, anterior cingulate cortex, and insula. These findings suggest that intertemporal choice of gains and losses might involve distinct valuation systems, and more importantly, separate neural interactions may implement the intertemporal choices of gains and losses. These findings may provide a new biological perspective for understanding the neural mechanisms underlying intertemporal choice of gains and losses.展开更多

Methods： A total of 120 female patients with overactive bladder syndrome were allocated to a treatment group of 80 cases and a control group of 40 cases on a voluntary basis. The patients in the treatment group received EA at four sacral points, and the treatment was given three times a week for 6 consecutive weeks, while the patients in the control group received oral administration of M-receptor antagonist tolterodine tartrate, which was given 4 mg each time, once a day for 6 consecutive weeks. Then the symptom scores were compared between the two groups before and after treatment. Results： At the end of treatment, the symptom scores showed statistical significant differences in comparing with those before treatment in both groups （both P〈0.02）; the symptom score in the treatment group was lower than that in the control group, showing a statistically significant difference （P〈0.05）. Conclusion： EA at four sacral points is an effective method for overactive bladder syndrome.展开更多

Blastula stage blastomeres acquire different identities as they have inherited different maternal materials which distribute radial symmetrically along the animal vegetal aixs in the full-grown oocyte, and are rearranged by the cortical rotation triggered by fertilization. The vegetal blastomeres demonstrate the different dorsalization potencies in the previous transplantation experiments. The data of blastomere explanting and RT-PCR analyzing indicate that the dorsal ventral bias also exists among the animal blastomeres even during the early blastula stage.展开更多
