🚀 Neuralink人脑植入芯片的首次人体试验及其成果

Elon Musk的Neuralink公司首次进行了人脑植入芯片的人体试验。Nolan Arbau成为首位接受植入的人类,他在100天的时间里,已经实现了脑机接口(BCI)控制光标速度和准确性的世界纪录。Nolan每天花费多达8小时参与Neuralink的研究会议,并在周末将个人和娱乐使用时间延长至每天10小时,每周达到69小时的BCI使用时间。他的速度从植入当天的4.6比特每秒(BPS)提高到3个月后的8 BPS,接近健全人使用鼠标的10 BPS。Neuralink的软件能够区分左键和右键点击,并且能够精确移动光标以点击笔记本电脑屏幕上的最小图标和按钮。这项技术的实际应用是,Nolan现在仅凭思考就能完成以前需要使用口棍(一种他含在嘴里与设备交互的工具)的任务。尽管Nolan已经能够熟练使用口棍,但他对BCI的评价是,一个月前他认为BCI和口棍一样好,如果不是更好的话,而且仍在改进中。Nolan现在不仅能玩简单的电脑游戏,如国际象棋和文明6,还能在Nintendo Switch游戏机上玩马里奥卡丁车,这超出了人们对早期阶段可能实现的功能的预期。Neuralink的主要目标是展示Link设备在日常生活中的安全性和实用性,而不仅仅是设置世界纪录或超越人类能力。尽管Nolan的测试中出现了至少一个问题,即手术后几周内一些植入脑组织的电极线开始回缩,减少了大脑与植入物之间的通信。Neuralink R1机器人在手术过程中将64根线植入大脑皮层,特别是运动皮层区域,每根线比人的头发还细,带有16个电极传感器,总共有超过1000个连接点。当线从大脑中回缩时,就会减少电极接口的数量,从而减少大脑连接的百分比。Neuralink的数据图表显示,从2月底开始,BCI的性能开始下降,但后来通过改进算法,Nolan的性能迅速恢复到8 BPS。

🔍 Neuralink植入物的挑战与未来计划

尽管Nolan的BCI性能有所下降,但Neuralink通过优化算法,使Nolan能够快速恢复到原来的8 BPS性能。在3月20日的直播中,Nolan展示了用意念下棋的能力。Neuralink认为,手术后Nolan颅内可能被困住了一些空气,导致一种称为气颅(pumilis)的状况,这虽然不会对Nolan的安全构成风险,但影响了他当前Neuralink植入物的潜力。如果电极线从脑组织中提取出来,就没有简单的方法将它们重新放回去。据华尔街日报报道,Neuralink已经提出了移除Nolan植入物的可能性,但目前没有迹象表明这将很快发生。Neuralink的Link设备设计为可移除和升级,内部人士表示,首次人体试验中遇到这样的挑战是预料之中的。尽管在动物身上进行了多次测试,但人脑手术的结果可能有所不同。Neuralink对食品和药物管理局报告说,他们相信已经找到了解决Nolan植入物遇到问题的方法,并计划在未来几个月进行另外两次人体植入手术。根据公司的潜在路线图,Neuralink的目标是在2024年植入10人,在2025年增加到27人,在2026年增加到79人。2021年,Neuralink在羊、猪和猴子身上进行了总共155次手术,2022年增加到294次。预计Neuralink将需要最多6年的时间来完成和验证首次人体试验的结果,主要研究期将在设备植入后的前18个月内进行,患者将每两个月与医疗团队检查一次,以监测进展并确保Neuralink设备按预期工作。同时,观众可以关注Nolan在X上的直播,了解他使用Neuralink能力的实时演示。

Elon musk's brain implant company

play00:02

neuralink has revealed new results from

play00:04

their first ever human trials we know

play00:07

that Nur Link's first human test subject

play00:09

has already accomplished something never

play00:10

seen before in the world of brain

play00:12

computer interface but the company has

play00:15

also run into at least one unexpected

play00:18

problem that needs to be

play00:23

overcome it's been just over 100 days

play00:26

since Nolan arbau became the first human

play00:28

being to be implanted with a neuralink

play00:30

and one brain chip the surgical

play00:32

procedure was conducted at the Baro

play00:34

Neurological Institute in Phoenix

play00:36

Arizona which is the world's largest

play00:38

treatment and research hospital for

play00:40

neurological diseases in those 100 days

play00:43

Nolan has already accomplished some

play00:45

unprecedented Feats during his first

play00:47

ever research session with nuring Nolan

play00:49

was able to set a new world record for

play00:51

human BCI cursor control that was day

play00:54

one during weekdays Nolan spends up to 8

play00:57

hours a day contributing to neuralink

play00:59

research sessions on weekends his

play01:01

personal and recreational use of the

play01:02

implants can exceed up to 10 hours per

play01:05

day he's been able to reach up to 69

play01:08

hours per week of brain computer

play01:10

interface with the N1 chip the standard

play01:12

for measuring speed and accuracy of

play01:14

cursor control is bits per second or BPS

play01:17

and that's what nurlink is calculating

play01:19

during these grid tests where you see

play01:21

the cursor moving around and clicking on

play01:22

different boxes on day one Nolan set a

play01:25

new world record of 4.6 BPS 3 months

play01:29

later Nolan is already achieving 8 BPS

play01:32

and is quickly approaching the same

play01:34

speed and accuracy of an able-bodied

play01:36

person using a mouse with their hand

play01:38

which is 10 BPS so he's close the

play01:41

nerling telepathy software is able to

play01:43

distinguish between left and right

play01:45

clicks and allow for movement of the

play01:47

cursor that is precise enough to click

play01:49

on the smallest icons and buttons of a

play01:51

laptop screen the real world result of

play01:54

this technology is that Nolan is able to

play01:56

use his thoughts alone to complete tasks

play01:59

that previously required his mouth stick

play02:01

literally a stick that he holds in his

play02:03

mouth and uses to interact with a device

play02:07

after 8 years of living with full body

play02:08

paralysis Nolan had become very

play02:10

proficient with using this physical

play02:12

control in his daily life he even told

play02:14

nurlink quote I thought that the mouth

play02:16

stick was a lot better than BCI a month

play02:18

ago when we compared them I saw that BCI

play02:21

was just as good if not better and it's

play02:24

still improving the games I can play now

play02:26

are Leaps and Bounds better than

play02:28

previous ones I'm beating my friend in

play02:30

games that as a quadriplegic I should

play02:32

not be beating them in not only can

play02:34

Nolan now play Simple computer games

play02:36

like chess and civilization 6 he's also

play02:39

been able to use the N1 to play Mario

play02:41

Kart on a Nintendo switch console which

play02:43

is even more than I would have expected

play02:45

to be possible at this early stage in

play02:47

the game it's important to remember here

play02:50

that the aim of the initial Prime study

play02:52

is not about setting World Records or

play02:54

beating human capabilities the primary

play02:56

goal is to demonstrate that the link

play02:58

device is safe and useful in daily life

play03:01

so a lot of the work that neuralink is

play03:03

doing is just remotely monitoring the

play03:05

technical performance of the device to

play03:07

try and measure the benefit that it

play03:09

provides to Nolan and his quality of

play03:11

life which so far appears to be

play03:13

overwhelmingly positive Noland told

play03:16

nurlink quote y'all are giving me too

play03:18

much it's like a luxury overload I

play03:21

haven't been able to do these things in

play03:23

8 years and now I don't know where to

play03:25

even start allocating my attention now

play03:28

of course this is a first of its kind

play03:30

medical procedure so it would be

play03:32

expected that some things will not work

play03:34

out as planned and neuralink is no

play03:36

exception here there's been at least one

play03:39

problem with the device that's already

play03:40

cropped up in Nolan's testing so what we

play03:43

know is that in the weeks following the

play03:45

surgery a number of the electrode

play03:47

threads that were implanted into Nolan's

play03:49

brain tissue started to retract

play03:51

essentially cutting off some of the

play03:52

communication between the brain and the

play03:55

implant during the surgical procedure

play03:57

nurlink R1 robot was used to insert 64

play04:00

threads into the outer layer of the

play04:02

brain the cerebral cortex and

play04:04

specifically this is targeted into the

play04:06

motor cortex region of the brain

play04:08

penetrating just a few millimeters deep

play04:10

into the tissue each thread is thinner

play04:13

than a human hair and Carries 16

play04:15

electrod sensors giving the link device

play04:17

a total of over 1,000 connection points

play04:20

into the neural network of Nolan's brain

play04:22

from here the electrodes can detect

play04:24

bioelectric pulses created by neuron

play04:26

activation within the cortex layer the

play04:29

link device us uses signals collected by

play04:30

the threads to create a digital

play04:32

representation of the brain activity

play04:34

that can be transmitted via Bluetooth

play04:36

into a nearby computer device so when

play04:39

the thread's retracted from the brain

play04:41

that decreased the number of electrode

play04:43

interfaces between the link implant and

play04:45

the motor cortex so losing one thread

play04:47

would be a 1.5% reduction in electrode

play04:51

count losing just three threads would be

play04:53

nearly a 5% reduction in brain

play04:55

connection we can see the effect of this

play04:57

in Nur Link's own data charts starting

play04:59

late in February the performance of the

play05:01

BCI started to drop off we can see that

play05:03

Nolan goes from 8 BPS down to five then

play05:06

four and as low as 3 BPS by mid-march

play05:09

but then the number recovers again

play05:11

quickly Nolan bounces back to 6 BPS by

play05:14

around the same time period that nurlink

play05:15

released the first live stream he was

play05:17

featured in on March 20th where we saw

play05:19

Nolan able to play chess on the stream

play05:22

with his mind nurlin explains this by

play05:24

saying that they honed the algorithm to

play05:26

make better use of the limited data

play05:28

being collected from the brain and we

play05:30

can see that Nolan is quickly back to

play05:32

his original performance of 8 BPS this

play05:35

was acknowledged by Nolan at a nuring

play05:37

company meeting that happened on March

play05:39

1st which he posted a recording of 2x on

play05:42

March 22nd Nolan said quote sure we're

play05:45

still working out the Kinks and stuff

play05:47

but once we get this figured out there's

play05:49

no reason for the implant not to be out

play05:51

there so this begs the question what

play05:53

happened well according to a report from

play05:55

The Wall Street Journal nurlink believes

play05:57

that some air was trapped inside Nolan

play05:59

skull after the surgery was performed

play06:02

this is a condition called pumilis now

play06:05

I'm not going to pretend like I'm a

play06:06

doctor here but it appears like mild

play06:08

cases of pumilis can be relatively

play06:10

harmless and are often resolved by the

play06:13

body reabsorbing the air so this doesn't

play06:15

appear to pose any risk to Nolan's

play06:18

safety but it does impact the potential

play06:20

of his current neuralink implant if the

play06:23

threads have extracted themselves from

play06:25

the brain tissue then there's no easy

play06:27

way to put them back in according to the

play06:29

wsj report neuralink has already floated

play06:32

the possibility of removing Nolan's

play06:34

implant but we have no reason to believe

play06:37

that this will actually happen anytime

play06:39

soon though one of the upshots for the

play06:41

link device is that it is intended to be

play06:43

removable and upgradable over time

play06:47

unnamed sources within neuralink have

play06:48

said that challenges like this were

play06:50

expected in the first test on a human

play06:52

patient although they didn't specify any

play06:54

reason why there would be a different

play06:56

result after doing the procedure on a

play06:58

human brain after dozens of test

play07:00

implants on monkey and pig brains the

play07:03

nuring sources say that the company

play07:05

remains optimistic that this problem can

play07:07

be resolved and that future implants

play07:09

will be able to capture more data and

play07:11

offer greater capabilities for human

play07:13

patients nurlink has already reported to

play07:15

the Food and Drug Administration that it

play07:17

believes it has fixes for the problem

play07:19

that was encountered with Nolan's

play07:21

implant according to the same sources

play07:23

reported by Wall Street Journal

play07:25

neuralink already has plans for two more

play07:27

human implant procedures in the coming

play07:29

months these will go forward once a

play07:31

safety review of Nolan's implant is

play07:33

completed nurlink reportedly maintains a

play07:35

goal to implant 10 people this year with

play07:38

the device according to a potential road

play07:40

map from the company that will increase

play07:42

to another 27 implants in 2025 and 79 in

play07:47

2026 in 2021 nurlink performed a total

play07:50

of 155 surgeries on sheep pigs and

play07:53

monkeys in 2022 that number grew to 294

play07:57

total surgeries so it's expected that

play07:59

the first human trial will take up to 6

play08:01

years for nurlink to complete and verify

play08:03

their findings the primary study period

play08:06

will take place over the first 18 months

play08:08

after the device has been implanted

play08:10

patients will check in with a medical

play08:11

team every 2 months to monitor progress

play08:14

and ensure the nurlink device continues

play08:15

to work as intended in the meantime make

play08:18

sure you follow Nolan on X at modded

play08:20

quad he started doing live stream

play08:22

demonstrations of his neur link

play08:23

abilities and it's pretty fascinating to
