Hacking Our Sense Perceptions

11 April 2019

Are humans limited to the senses we’re born with? Or is it possible to hack the brain and create new senses? Even if we could, would we want more senses than we already have? This week we’re thinking about hacking the brain: perception beyond the five senses.

The idea of “hacking” the brain might sound a bit scary or sci-fi, but we’re not talking about brain chips or anything so invasive. What we are talking about is being able to add novel human senses, like a bat’s echolocation or a bird’s magnetoception (the ability to perceive magnetic fields). Wouldn’t that would be cool?

In a sense, we’ve already been hacking the brain in this way for a long time. Just think of the cane blind people use to see. It’s relatively simple technology and it doesn’t involve brain surgery to work, yet this is a simple way to hack the brain.

You might say that blind people don’t literally see with the cane. They navigate their environments with it, but that does not amount toseeing. The cane doesn’t give the blind person a sense perception they lack.

It’s true that a cane cannot endow a blind person with vision. However, we should not underestimate the power of the cane in the blind person’s hand. It’s more than just a mere navigation tool. As the phenomenologist Merleau-Ponty said, the cane gets “incorporated” into the blind person’s body. It becomes anextension他们的手。也许他们看不见地面,但他们可以用手杖感觉到地面!盲人的大脑被黑了,没有任何大脑植入。他们所需要的只是一根简单的手杖。

But how does this constitute "hacking the brain"? It's hacking because the brain takes information from the cane and integrates it so seamlessly into experience that the cane starts to feel like part of the body, part of the perceptual system. Now, this might not sound very novel or exciting, ifthisis all I mean by “hacking” the brain, but the example of the cane was just to illustrate how technologically simple and unobtrusive this kind of hacking can be. The cane does not exhaust the possibilities.

Brain hacking technology doesn’thaveto be very advanced. However, think about what could be achieved with today’s sophisticated technology. More advanced brain hacking technology has already been developed, so this is not just the stuff of sci-fi. For example, there are smart vests that allow not only blind people to see but also deaf people to hear using vibrations on their skin. And the same technology can be utilized to add novel human senses, not just those that most humans already have.

But the question remains. Can blind people reallyseewith this vibrating vest? Can deaf people reallyhear? I already conceded that the blind person with a cane doesn’t literally see, so why would it be any different with a vest?

The difference is the amount of information you can get from the vest versus the cane. The only information the cane gives is what is on the ground in front of the person. It can tell you if there are obstacles or steps or other changes on the surface. The vest, on the other hand, provides much richer information of the environment. It uses a camera to translate visual information into vibrations, which creates a complex picture of the environment. In the case of the normally sighted person using their eyes to see and the blind person using the vest to see, roughly the same visual information is sent to the brain to be processed.

当然,大脑本身是看不见的,但是有机体——以正确的方式被体现出来的人,用正确的感知器官以正确的方式连接到大脑,才是看得到的。大脑并不关心它是如何获得这些信息的,这就是为什么它可以以这种方式被黑。马甲实质上成为了一个全新的感觉器官,就像拐杖无缝地融入盲人的身体一样,马甲也是如此。

As a person is learning to use the technology, whether cane or vest, they are aware of it as something external and unintegrated. But fairly quickly the technology becomes incorporated and fades into the background of experience. It’s like when you put on a pair of glasses. At first you might feel different and aware of something propped on the end of your nose. But quickly you stop noticing the glasses and only notice what you can now see with their aid.

考虑到这种惊人的可能性,这项技术是一个非常令人兴奋的发展。这意味着那些失去或从未拥有特殊人类感官的人现在将能够拥有这些感官,而无需进行昂贵的侵入性手术,比如人工耳蜗植入。这也意味着我们可以添加新的人类感官,这是我们想象不到的。

Perhaps now we will finally be able to answer that vexing question famously posed by philosopher Thomas Nagel—whatisit like to be a bat?

I have been watching human

I have been watching human development for a relatively short time. Probably only the last twenty-five to thirty years of my life. Most of us, sooner or later, read something about evolution---whether we agree with it, disagree, or are rabidly opposed to the entire 'notion'. I have remarked, in print and to friends, regarding what seems to me significant about modern humans. Children are developing, psychologically; emotionally; and consciously at earlier and earlier ages. 'Gifted' children are becoming more the norm than the exception, in all sorts of ways, with all sorts of talents. This must have roots in more than curricula and teaching techniques---a 'totality of circumstances' perhaps. If Jean Piaget were alive today, my guess is he would say, 'well, I was trying to tell you so'. Or, he may be just as puzzled as others among us. The evidence is, to me, pretty convincing, although my best points of reference are my own grandchildren. They are not like children of their age were fifty years ago. I have asked other people if they have noticed these changes, but, once again, the reference frame is skewed because most of the people I speak with are thirty to forty years my junior---they have a shorter experiential mode from which to form hypothesis or theory...they are so close to the forest, the trees are in camouflage. Or something like that. It is, I think, a braver, newer world---perhaps there WAS something to Stephen Jay Gould's notion of 'punctuated equilibrium' Yeah, I know-the whole thing is mostly laughed at now. But, Gould was an insightful character, in his own right-so who knows what HE would think (or have to say)-not so many years after his own untimely demise? There is something happening here---it is not fully clear what that is. Yet. If evolution, in se, evolves, just what would that mean? I am surprised (a little) that more thinkers and public intellectuals are not talking about that notion. I guess they do not wish to stick their feet in potentially hot water. I am not so fearful. Have no reason to be.

I don't think we will ever be

I don't think we will ever be able to know what it is like to be a bat. I say that knowing full well there are human beings who echolocate - the most famous of them being James Holman. We already know the brain can manufacture senses from very rudimentary implants from the success of cochlear implants. Miguel Nicolelis at Duke has done the incredible in linking minds to motion outside the body. He has demonstrated a clear speed improvement in these scenarios that also demonstrates that such a body sense will not be merely extending but enhancing. If we could induce synesthesia if might count as another sense as well. Drugs can already do that somewhat, I suppose, though that is not, I think, what you are hacking at.

I don't know what it is like to be Laura, or Harold or Ken. How can we ever know these things?

Certainly, I would like to be a Mentat from Dune or better yet see the C-beams glitter in the dark near the Tannhauser gate like Roy Batty in Blade Runner. If we can build sensors we can wire them to our brains. I look forward to any sensation I can comprehend. But mostly I want comprehension. Wire me to that. Then I promise not to go bat crazy.

If we can expand our sensory

If we can expand our sensory capacity, I doubt our brain is ready to handle it. Assume ghost exists, and somehow I manage to see it, will that not affect my everyday living? and say that I can see through the cloud and into the space millions of light year away, how quickly my eye need to adjust as I look back down and cross a street. I just think that the sets of sense given are already the product of natural selection, any drastic amendment does not guarentee fabulous experience.

This is ever more fascinating

This is ever more fascinating stuff. Dancing robots. Vibrating vests. The kids I wrote about awhile back are developing nicely. They are clever. The eldest, whom we were concerned for because of his communications, has overcome arrested development issues. A little counseling and a lot of patience. The wife and I are doing OK for old people. My brother is more creative than ever. Our semi-retired educator and neuroscientist in Ecuador remains vibrant, active and generally witty: he, the dyslexic, voted least likely to be anything. You just never know...
