<p class="bodytext">This is the brainstem’s big moment. Around the time of birth and during the following three or four months, the brainstem performs its role as central dispatcher with little interference. However, the brainstem is linked to other structures, such as the hippocampus and cortex. These structures are developing rapidly and the connections between them are growing stronger. During the coming months, the cerebral cortex gradually assumes its role in modulating the activity of the brainstem.<p class="bodytext">脑干, 从出生到3-4个月,脑干起了中枢作用, 这时候海妈体和大脑皮层都在迅速的发展, 以后大脑皮层逐步的接替了脑干的作用.<p class="bodytext">A popular word today is multimedia, but the brainstem has been in that business for a long time. The brainstem receives incoming sensations through separate channels, or “modes.” Information from the eyes is in the “visual mode,” what a baby hears is in the “auditory mode,” and what he feels by touching his skin is in the “somatosensory mode.” His brainstem integrates the input from the different channels, a multimodal process.<p class="bodytext">The brainstem is also “interactive.” When a baby hears a sudden loud noise, he startles. The muscles of his whole body jerk in unison. When he sees a face nodding above him, he moves his head and eyes to follow it. His brainstem receives the signals and automatically activates the appropriate muscles.<p class="bodytext">脑干从各个感觉器官接受信息, 然后作出反应. ( 基本上这些反应都是属于条件反射类的生物反应. <我写的>)<p class="bodytext">注:请不要延伸出去, 认为既然脑干是干这事的,我们正好闪卡给BB刺激. 一定有大大的好处. |
