“使用共享前運(yùn)動(dòng)神經(jīng)元來(lái)控制多個(gè)肌肉可能是運(yùn)動(dòng)系統(tǒng)的一般特征，” 斯坦尼克說(shuō)。“有關(guān)大腦的其他部分的其他研究，重要的是要記住，單個(gè)神經(jīng)元可以受到多個(gè)下游區(qū)域的影響。”
研究人員使用他們的技術(shù)有興趣進(jìn)一步使小鼠跳回到它的大腦中，zui終繪制回路一直到皮層。但首先，他們計(jì)劃深入研究前運(yùn)動(dòng)神經(jīng)元和運(yùn)動(dòng)神經(jīng)元之間的連接。
“這只是了解這些顏面部動(dòng)作的控制的一小步，” 斯坦尼克說(shuō)。“在咀嚼，飲水和講話(huà)中，我們只能看著兩塊肌肉和至少有其他10個(gè)肌肉在活動(dòng)，仍然需要大量的工作來(lái)觀察這些其他肌肉，也只有這樣，我們才能得到所有的這些工作如何作為一個(gè)單元來(lái)協(xié)調(diào)這種行為的一個(gè)完整圖片。”
實(shí)驗(yàn)原理：高壓蒸汽滅菌是將待滅菌的物品放在一個(gè)密閉的加壓滅菌鍋內(nèi)，通過(guò)加熱，使滅菌鍋隔套間的水沸騰而產(chǎn)生蒸汽。待水蒸汽急劇地將鍋內(nèi)的冷空氣從排氣閥中驅(qū)盡，然后關(guān)閉排氣閥，繼續(xù)加熱，此時(shí)由于蒸汽不能溢出，而增加了滅菌器內(nèi)的壓力，從而使沸點(diǎn)增高，得到高于100℃的溫度。導(dǎo)致菌體蛋白質(zhì)凝固變性而達(dá)到滅菌的目的。
 在同一溫度下，濕熱的殺菌效力比干熱大，其原因有三：一是濕熱中細(xì)菌菌體吸收水分，蛋白質(zhì)較易凝固，因蛋白質(zhì)含水量增加，所需凝固溫度降低（表Ⅵ-2），二是濕熱的穿透力比干熱大（表Ⅵ-3）；三是濕熱的蒸汽有潛熱存在，每1克水在100℃時(shí)，由氣態(tài)變?yōu)橐簯B(tài)時(shí)可放出2．26kJ（千焦）的熱量。這種潛熱，能迅速提高被滅菌物體的溫度，從而增加滅菌效力。

"Using shared prefrontal motor neurons to control multiple muscles may be a general feature of the motor system," said Steynick. "Other studies of other parts of the brain, it is important to remember that a single neuron can be affected by multiple downstream regions."
Researchers using their technique are interested in further jumping mice back into its brain, eventually drawing the loop all the way to the cortex. But first, they plan to dig deeper into the connections between the motor and motor neurons.
"It's only a small step toward understanding the controls on these facial movements," said Steynick. "In chewing, drinking and speaking, we can only look at two muscles and at least ten other muscles in motion. We still need a lot of work to observe these other muscles, and only then can we get all of these things A complete picture of this behavior as a unit. "
Experimental principle: Autoclaving is to be sterilized items placed in a closed autoclave, by heating, so that the water between the autoclave compartment boil and produce steam. Until the water vapor rapidly drained the cold air from the exhaust valve, and then close the exhaust valve to continue heating, this time because the steam can not overflow, and increase the pressure inside the sterilizer, so that the boiling point increased, A temperature above 100 ° C is obtained. Resulting in coagulation and denaturation of bacterial proteins to achieve the purpose of sterilization.
 At the same temperature, hot and humid bactericidal effect than dry heat, for three reasons: First, hot and humid bacteria in the body to absorb moisture, protein easier to coagulate, due to protein moisture content, the required freezing temperature decreased (Table VI-2) (Table VI-3); third is the hot and humid steam latent heat exists, each 1 g of water at 100 ℃, from the gaseous state can be released when the liquid 2.26kJ (thousand Coke) of the heat. This latent heat, can quickly increase the temperature of the object to be sterilized, thereby increasing the effectiveness of sterilization.
