leapfrog guidance specific to the technology, doled out a handful of breakthrough-device designations to brain-computer interfaces and, in April, issued its first approval to a system that translates brain signals into movements of a hand and wrist brace, allowing stroke patients to relearn how to grasp objects.

And while these rapid-fire developments make it easy to get swept up in the hype surrounding brain-computer interfaces, because of how sensitive neurotech can be, it’s important to realize that plenty of it is just that: unsubstantiated hype.

 

“More often than not, there’s a lot of people promising things that the tech can’t actually do,” Justin Sanchez, Ph.D., the technical fellow in charge of Battelle’s life sciences research business, told Fierce Medtech.

“It’s so important to get excited by the potential of neurotech and where it could go, but also to be really grounded on that technology and what it does and what science needs to happen in order to make it a reality,” he continued. “Understanding the difference between what is real and what is not when it comes to neurotech is such an important issue, and it’s one that, at Battelle, we take extremely seriously.”

Battelle’s brain-computer interface work began in the realm of spinal cord injuries with the development of a system that analyzes brain activity to detect a paralyzed individual’s intent to move their hand or arm, then uses that information to stimulate those muscles through a forearm sleeve.

That fundamental technology has since been expanded into stroke rehabilitation and, through Battelle’s long-running partnership with the U.S. Defense Advanced Research Projects Agency—where Sanchez was previously director of the biological technologies office—the ongoing development of a noninvasive brain-computer interface that involves an external headset and injected nanoparticles for neural stimulation.

In a Q&A with Fierce Medtech, Sanchez offered up the two major questions that can separate science from sci-fi in brain-computer interfaces and plotted out the technology’s next moves.

科学与科幻的分离:巴特尔的贾斯汀·桑切斯论平衡脑-机接口的嗡嗡声

激烈的生物技术

Andrea Park于2021年9月1日发布

脑机接口在医疗技术领域风靡一时,几乎每周都有一种新的“读心术”头戴式装置或神经刺激植入物问世。

以谨慎著称的FDA甚至也加入了这场运动。仅去年一年,它就提供了蛙跳制导针对这项技术,发放了少量突破性设备名称四月份,该公司首次批准了一种将大脑信号转换为手和腕托动作的系统,使中风患者能够重新学习如何抓握物体。

虽然这些快速的发展使得人们很容易被围绕着脑-机接口的炒作所包围,因为神经技术是多么敏感,但重要的是要认识到,其中很多只是:未经证实的炒作。

负责巴特尔生命科学研究业务的技术研究员贾斯汀·桑切斯(Justin Sanchez)博士告诉Fierce Medtech:“通常情况下,有很多人承诺,这项技术实际上无法完成的事情。”

“对神经技术的潜力和它的发展方向感到兴奋是非常重要的,但也要真正基于这项技术,以及它所做的事情,以及为了使它成为现实需要发生什么样的科学,”他继续说。“对于神经症来说,理解真实与非真实之间的区别是一个非常重要的问题,在巴特尔,我们非常重视这个问题。”

巴特尔的脑-机接口工作始于脊髓损伤领域,他开发了一种系统,该系统分析大脑活动,检测瘫痪者移动手或手臂的意图,然后利用该信息通过前臂袖套刺激这些肌肉。

这项基础技术已经扩展到中风康复和,通过Battelle与美国国防高级研究计划署(Sanchez曾任该署生物技术办公室主任)的长期合作关系,目前正在开发一种非侵入性脑-机接口,该接口包括一个外部耳机和用于神经刺激的注入纳米颗粒。

在与威猛医疗科技公司的问答中,桑切斯提出了两个主要问题,这两个问题可以在脑-机接口中将科学与科幻区分开来,并规划了该技术的下一步行动。
