见证黄河源危机

绿色中国（综合版） 2006年第4期 49-57页

作者：李沫萱 john novis

从恐怖的大冰崩到日渐干涸的姐妹湖，从“跳舞公路”到陷入赤贫的牧民，作者目睹了黄河源区的重重危机。在气候变化的威胁下，黄河的安危已然命悬一线，陷入困境的不仅仅是一个地区的牧民，整个流域和整个国家都面临着严峻挑战。

好莱坞大片《后天》所展现的大灾难——纽约在瞬间被滔天海水淹没,观者在惊叹电脑特技如此真实、场景如此恐怖之后或许会一笑置之,但如果全球气候变暖继续恶化,世界范围内冰川融化加快,纽约灾难的发生,如果不是在"后天",那会在何时?

Objective: The present study aimed to investigate and to compare the electrophysiological changes in bipolar patients and healthy subjects during the execution of a saccade task. Materials and Methods: The subjects had to respond to a fixed visual stimulus presented by a LEDs bar. We executed an ANOVA (one-way) and post hoc Scheffé test to examine the difference of absolute alpha power and reaction time among four groups: control, depression, manic and euthymic. We observed the frontal, parietal and occipital regions. The paired t test was realized on each electrode and group to compare the pre and post moment in the task. Results: We observed a statistical difference among the groups for the behavioral variable—saccade reaction time. For the electrophysiological variable—absolute alpha power, we did not find significant difference between the moments (pre and post stimulus presentation) for none of the electrodes of each bipolar group. However, the results pointed out to a difference between the moments for F3, P3, O1 and O2 electrodes for control group. Conclusion: We cannot affirm that the task influences the cortical activity of the patients. It is possible that the method used to analyze the data is not the adequate. The time-frequency analysis could be better to analyze the present data. We also observed that the absolute alpha power could be considered a marker of bipolar disorder, but not of the different states (i.e., mania, depression, euthymia).
