海马

Rapid eye movement sleep consists of a dreaming state in which there is activation of the cortical and hippocampal electroencephalogram, rapid eye movements, and loss of muscle tone. Although REM sleep was discovered more than 50 years ago, the neuronal circuits responsible for switching between REM and non-REM sleep remain poorly understood. Here we propose a brainstem flip-flop switch, consisting of mutually inhibitory REM-off and REM-on areas in the mesopontine tegmentum. Each side contains GABA (gamma-aminobutyric acid)-ergic neurons that heavily innervate the other.

快动眼睡眠是一个包括有皮层和海马脑电活动的睡梦状态，可见眼球的快速运动和肌张力减低，尽管快动眼睡眠已经被发现50余年了，对其与非快动眼睡眠之间的神经回路却知之甚少，我们用脑干触发转换器，包括脑桥背盖区一个互相抑制的快动眼-关、快动眼-开区域，每侧均包含高度互相支配gamma氨基丁酸能神经元。

The expression of TrkA had an obviously increasing tendency in the cortex of telencephalon from E15 day to E17 day.

胎鼠纹状体、海马的发育较晚，E17天开始发育，TrkA在其内的表达与皮质内相似。

The tetanic of electrical stimulation, which induce LTP in spinal dorsal horn, can caused hyperalgesia lasted on several days.

与海马LTP的研究相比，脊髓背角LTP的研究才刚刚起步，有许多问题有待探讨。

The active ingredient in marijuana – tetrahydrocannabinol or THC – interferes with synchronized activity between neurons in the hippocampus of rats, according to a paper published in the December 2006 issue of Nature Neuroscience.

活性成分大麻-四氢或货柜码头处理费-干扰了同步活动之间的神经元在大鼠海马，根据一项发表在2 0 06年1 2月发行的自然神经科学。

Objective To investigate the effect of thrombin preconditioningon the apoptosis of hippocampal neurons and explore the potential mechanisms.

目的：研究凝血酶预处理对大剂量凝血酶诱导海马神经元凋亡的影响，阐明TPC的保护作用。

Together, these results indicate that the negative cell cycle regulator, Tob, is involved in hippocampus-dependent learning and memory.

这些结果表明，CA1区的Tob参与海马依赖性的学习记忆过程，参与对突触可塑性的调控，这种作用很可能与其在细胞周期中扮演的角色完全不同。

Our previous study indicates that Tob in the hippocampal CA1 region is involved in declarative learning and memories that require the hippocampus.

前面的工作表明，Tob参与海马依赖性的陈述性学习和记忆的巩固。

Here, we show that the same tSOS applied in the waking brain also induced an increase in endogenous EEG slow oscillations (0.4 1.2 Hz), although in a topographically restricted fashion.

更为有趣的是，在EEG的theta频段(4 8 Hz)，发现活动也有明显而又广泛的增强，而且，与海马相关的记忆能力，也有提高。

Abstract］ Objective To determine indirectly the degree of total gene expression in the hippocampal neurons of Alzheimer's disease.

摘要］ 目的间接了解Alzheimer's病海马神经元总体基因表达水平。

The relative size of the hippocampal formation in relation with the total volume of the brain is often conserved in most of the mammalian species.

绝大多数的哺乳类动物海马的大小取决於脑容量的大小，但是鲸类这一部位的发育相对不完全。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
