There are many ways in which to build new bodies across scale, from the biomolecular to the scale of tissues and organs.
有許多方法可以超越常規(guī)來(lái)建立新的身體，從生物分子層面到組織和器官層面。
Today, I want to talk about one area of NeuroEmbodied Design,
今天，我想談?wù)勆窠?jīng)體現(xiàn)設(shè)計(jì)中的一個(gè)領(lǐng)域，
in which the body's tissues are manipulated and sculpted using surgical and regenerative processes.
使用外科手術(shù)和再生技術(shù)，對(duì)人體組織進(jìn)行處理和重塑。
The current amputation paradigm hasn't changed fundamentally since the US Civil War
自美國(guó)內(nèi)戰(zhàn)以來(lái)，截肢規(guī)范并沒(méi)有發(fā)生根本性的改變，
and has grown obsolete in light of dramatic advancements in actuators, control systems and neural interfacing technologies.
隨著執(zhí)行器、控制系統(tǒng)和神經(jīng)接口技術(shù)的迅猛發(fā)展，原來(lái)的截肢規(guī)范早已過(guò)時(shí)。
A major deficiency is the lack of dynamic muscle interactions for control and proprioception.
一個(gè)主要的缺陷是缺少了用來(lái)進(jìn)行控制和本體感知的動(dòng)態(tài)肌肉間的相互作用。
What is proprioception? When you flex your ankle, muscles in the front of your leg contract,
什么是本體感知呢？當(dāng)你彎曲腳踝時(shí)，腿前部的肌肉就會(huì)收縮，
simultaneously stretching muscles in the back of your leg.
同時(shí)，腿后部的肌肉則會(huì)伸展。
The opposite happens when you extend your ankle.
當(dāng)你伸展腳踝時(shí)，肌肉的作用正好相反。
Here, muscles in the back of your leg contract, stretching muscles in the front.
當(dāng)腿后面的肌肉收縮時(shí)，腿前面的肌肉就會(huì)伸展。
When these muscles flex and extend, biological sensors within the muscle tendons send information through nerves to the brain.
當(dāng)這些肌肉彎曲和伸展時(shí)，肌肉肌腱內(nèi)的生物傳感器通過(guò)神經(jīng)向大腦發(fā)送信息。
This is how we're able to feel where our feet are without seeing them with our eyes.
這就是為何我們根本不用看就能感覺(jué)到腳的位置。
