METHODS: Exposed cutaneous branches rooted in rami posterior nervi spinalis and dominated muscles by exciding the median skin at the back of the rat's neck, given electric stimulation to the muscles by Low-frequency pulse transmitter. The output range was Voltage 0-40 V, frequency 1-111 Hz and pulse width 0-1 000 ms.

切开大鼠颈后正中表皮，显露脊神经后支皮支及其所支配的颈部后外侧肌群，使用低频脉冲发射器对上述肌肉进行电刺激，发射器的输出范围为：电压0~40 V，频率1~111 Hz，脉宽0~1 000 ms。

Methods40 adult male SD rats were used in this study and divided into 4 groups at random: normal group, aging model group, TNY treatment group, and negative control group, each group had 10 rats. The subacutely aging rats were made by injecting Dgal into the rats' abdominal cavity continuosly. The learning and memory ability of rats in each group were detected with Morris water maze. The monoamine transmitter contents in hypothalamus and hippocampus were detected with HPLCECD.

方法选用成年雄性SD大鼠40只，随机分为4组，每组10只：正常组、衰老模型组、TNY用药组、阴性对照组。D半乳糖连续腹腔注射制作亚急性衰老的大鼠模型，采用Morris水迷宫检测各组大鼠的空间学习记忆能力及采用高效液相色谱电化学法检测各组大鼠下丘脑、海马NE，DA，5HT的含量。

Soon, broadcasting beeps from a radio-transmitter attached to a collar around his neck, Mara joins the three other tigers – Mudka, Sundari, and Dasa - that I have already radiocollared in Nagarahole that month.

很快，从它脖子的项圈上的无线电发射机收到了&吡吡&的讯号。玛拉加入了这个月里我戴上了无线电项圈的其他三只老虎——玛德卡、桑黛丽和达莎——的行列。

Results indicated that the GABAnergic system inhibition and pre-synaptic transmitter exhaustion may play an important role in short-term plasticity. And the short-term depression in thalamocortical visual pathway was strengthened when the cortex circuit get mature.

结果表明：GABA能系统的抑制作用和突触前递质衰竭很可能是决定该回路短时程抑制特性的主要因素；幼年大鼠与成年大鼠视觉系统短时程突触可塑性的对比研究表明，随着皮层回路的成熟，视觉丘脑至皮层通路的短时程突触抑制作用越来越强。

The results suggest that there is prominent short-term synaptic depression in the rat thalamocortical visual pathway. Presynaptic transmitter depletion and postsynaptic GABAergic inhibition are the main possible mechanisms of this synaptic depression. The short-term synaptic depression is helpful in neuronal correlated firing detection.

以上结果表明：丘脑皮层视觉通路具有显著的短时程突触抑制特性，突触前的递质耗竭和突触后的GABA能抑制系统很可能是产生视通路短时程突触抑制作用的主要机制，突触抑制作用有助于视觉系统对同步发放活动的检测。
