Still a favorite: Using space and time to encode vibrotactile information: toward an estimate of the skin’s achievable throughput

Since 2015 there’s a paper that has absolutely eaten me alive, neuron by neuron. It’s called “Using space and time to encode vibrotactile information: toward an estimate of the skin’s achievable throughput (Eagleman, Novich)” and causes my mind to be absolutely paralyzed by possibilities. Sensory substitution! What a thought, Eagleman!

Of course, Paul Bach-y-Rita was one of the original OG’s in this realm.

& now, Elon Musk continues to seek talent for up-&-coming Neuralink – which promises to offer high-bandwidth brain-to-computer interfaces. Hm. Not a bad idea, especially when you consider the therapeutic applications of existing brain-to-computer technologies.

To research or work on any of these technologies would be the opportunity of a lifetime, & I’d cancel pretty much everything in my life right now to pursue them if only I knew how. In the meantime the opportunity to sit back and learn is available & my cynical little mind is already shouting out some words of caution.

BRAIN-TO-COMPUTER-INTERFACES-ARE-NEVER-GONNA-HAPPEN!, says cynical brain

Well, nothing interesting that ever happened was ever-going-to-happen. New inventions are just crazy, that’s how it is! 

(this back-and-forth arguing continues). The primary concern is whether or not a high-bandwidth brain-to-machine interface for general-purpose use would be a good thing. Musk & others are right when they say that a keyboard isn’t enough to transmit a certain amount of information back-and-forth. But is that enough to support the overall claim that as it relates to human beings using and interfacing with information technology, quality of communication is proportional to the bandwidth of the information being passed along? Childish idealism runs rampant in my thoughts now – I’d like to go to coffee w a clever human like Elon & ask them, ‘will the problems you foresee with AI actually be solved by brain-machine interfaces or will they be worsened? Will the malicious capabilities of technology be diminished if humans are more closely linked w technology?’ It seems even a pen and paper (even morse code!) are often not enough for humans to communicate effectively, promptly, or sufficiently. It leads me to wonder if the tech-augmented hippocampus & cortex, adorned with messy glued-on silicon chips, might not be a devastatingly unhealthy Matrix-esque nightmare of limbic slop.

That coffee date won’t be happening anytime soon so in the meantime I’ll have to scroll from afar & hope these technologies work, & serve the common good.

Still a favorite: Empirical explorations of mindfulness (Conceptual and methodological conundrums)

& a must-read – especially for anyone hoping to be well-informed about health claims related to mindfulness, meditation, yoga, etc

Poetry challenge from RG: Vastness

Vastness

 

Most folks will say “look up! at that little twinkling star”,

& maybe rattle numbers off – “it’s really, REALLY far!”

suppose it’s true, cosmos are large, perhaps they’re kinda big

but look down at your bag of skin and let your daydreams dig

Seven billion people roam our “vast” tiny Earth

But seven billion billion billion atoms teem within one’s girth

They talk and play and scream and die as we all are right now

They love and hate and question fate and probably tip cows

All the while praying watching, wondering what they are

Colossal chemists peering in from microscopes afar

So don’t feel too small or look to stars to find some spacious wealth

The vastness of a universe is really in yourself

 

 

 

Do you cry after caffeine intake?

I do. It’s weird

Coffee is a devilish drug with a tendency to cultivate dependence and craft caffeinated chains between itself and the user. As I type this I’m maybe a few ounces (probably 30-50mg of caffeine) into a cup of coffee &, as often happens, I started crying in what totaled to a brief 10-second spurt. Playing on my mental radio was a sudden dialogue with a formless stranger about how beautiful my cats are, how grateful for them, etc. An image of myself much older came to mind; I was seeing an old picture of the cats and hadn’t seen that old picture in some time and I was crying tears of gratitude.

This mental trip took place in less than 4-5 seconds, was profound, colorful, and detailed, and took me straight out of the room I was sitting in. There was a glowy feeling of being decades older and shown these gorgeous pictures of these gorgeous cats. It was less a thought process and more of a vision or fleeting headline on the newsreel of my frontal lobes.

It immediately passed and I felt funny for having had the experience yet again. Self aware, un-emotional, and nonreactive to what had just occurred. This type of thing occurs very often after coffee but it was quite some time before I realized that. I thought I was the type of person who had an early morning cry session, or a few chaotic ones (always of about 10-20 seconds maximum) but the link with caffeine became clear after a long period of daily journaling. Will post an excerpt soon but just wanted to leave this note here for myself later. With that said, I’m off to finish this coffee
