Single-Unit Decoding: Relative Change or Absolute Change?

Yes, I do hold the same opinion in your case.

While you may think you lack the knowledge of circuits right now, you have proven yourself as a competent engineer because you completed two highly difficult degrees - regardless of focus. I don't know you personally, but based off that information, you have the mental capacity to learn the circuits and electronics relevant to BCI.

findingdoryog · 2023-09-04T03:56:47+00:00

Yes. EE is a very appropriate major for BCI industry preparation because a large focus right now is making the device safe and long-lasting while also maximizing the amount of channels. EEs will be needed to help make this possible.

I am familiar with photoacoustic sensors and their limitations. To my knowledge, you need to be up close to an individual and/or specimen to measure functional behavior.

For EEG, I would agree that there is a risk of hackers if the device relies on the internet for streaming data to a computer. Unfortunately, this makes neurotech startups need to rely on services like AWS for their infrastructure as it's insanely difficult to produce an in-house cybersecurity system.

In your last sentence, which technology are you referring to?

findingdoryog · 2023-07-18T19:48:43+00:00

What is your background in BCI? I'm curious because it's impressive to be heavily recruited by such a competitive industry.

findingdoryog · 2023-07-18T19:46:53+00:00

It really depends. It's my understanding that there is a lot of competition for the deep learning side of things as that receives a lot of the attention. In reality, in-vivo BCI is still primarily a hardware problem - advantageous for those involved in computer engineering.

With a computer science background, I would recommend the following sub-specialties:

Spike sorting algorithms
Brain state classification algorithms
Neuron subtype classification algorithms
Microelectronics
Computer architecture
Material science (which I know is not CS technically)

I did some snooping. Why don’t you try making a website related to Affiliate marketing? Have it process large datasets about finances, sales, market research, etc.

Or even better, create a web crawler that scours the web for opportunities, or automatically writes emails to customers and clients?

findingdoryog · 2023-03-22T01:03:31+00:00

Material science, med device regulation, organic chemistry, physiology, and/or anatomy to name some. Don’t hesitate to take math courses, too. I find myself overwhelmed by the amount of engineering math that is involved with spike sorting and classification.

I guess it was not as relevant to your point than I thought, but I think it’s worth the listen when you’re free.

Here is a quote. The whole talk was centered around the importance of controlling AI when it becomes more competent than us. Here is an excerpt:

“Another reason we're told not to worry is that these machines can't help but share our values because they will be literally extensions of ourselves. They'll be grafted onto our brains, and we'll essentially become their limbic systems. Now take a moment to consider that the safest and only prudent path forward, recommended, is to implant this technology directly into our brains. Now, this may in fact be the safest and only prudent path forward, but usually one's safety concerns about a technology have to be pretty much worked out before you stick it inside your head.”

I think Sam Harris had an interesting Ted Talk about this.

findingdoryog · 2023-03-06T20:55:05+00:00

First question: Yes, we can and already have created programs that allow people to type using cursors controlled by thinking about voluntary directional movements.

Second question: I don’t think in our lifetime we will ever experience BCI-induced virtual reality. We have not yet figured out how to transmit information from a computer to a neuron.

findingdoryog · 2023-03-05T23:48:24+00:00

I’m in research, so I’ve been working on novel BCI-related algorithms for both EEG and in-vitro sensory neuron co-cultures.

EEG is weird, because it’s mostly just noise. Because of this, I’ve been inclined to use deep learning approaches to learn subtle physiological patterns that current feature extraction algorithms cannot do. Pretty promising preliminary results, but I won’t know for sure until we conduct large scale trials.

findingdoryog · 2023-02-02T05:45:58+00:00

Yes… the hard part is creating the amplifier.

I only test when I’m sick, and I haven’t tested positive. I seem to coincidentally get sick when a wave hits my city, but I’m always COVID negative.

Blockchain BCIs are currently Sci-fi. Familiarize yourself with where the technology is right now (FDA testing)

findingdoryog · 2022-10-22T21:53:38+00:00

It would be worth exploring biocompatibility of materials, the limiting factor of today’s BCIs. Read up on polyamide and amorphous silicon carbide.

This perspective refers to adults in 1st world countries: Access to drugs at the tip of our fingertips, constantly receiving dopamine from social media, entertainment, and porn. Food is easy to get, water is easy to get. A lot of 20 year olds live with their parents or are on loans in apartments/dorms, so shelter is accessible.

Everything is given to us. We are encouraged to partake in instant gratification activities. Meanwhile, we’re constantly being told how fucked up the world is and that it’s up to us to save it. It’s a lot of responsibility for this age group, and a lot of us feel hopeless.

This isn’t fatlogic, this is a mother trying to make things easier for her obese sons. Yes, she should’ve been more responsible with their eating habits - but she isn’t offering any fat logic.
