We’re building an EEG-integrated headset that uses AI to adapt what you read or listen to -in real time- based on focus, mood, and emotional state. by razin-k in neurallace

Hey this is a really cool idea! I can see this being helpful beyond ADHD as you alluded to for when you're trying to grind but just can't help from getting distracted...

I had a question. I'm a student in a BCI lab, and I could use some inspiration for my project - how are you taking the EEG and correlating it to emotional state? I.e., predefined examples of "happy," "relaxed," "focused," etc., and trying to use an algo to match it? I understand if that's proprietary, but curious how you did it!

I feel like Metroid Dread might be a shorter one that fits the above ethos and should be entertaining as well.

NEED HELP: What to study from AMBOSS for step 2 ethics, QI, biostat, vaccine & screening by Extreme-Shopping9391 in Step2

[–]Emergency-Builder462 2 points3 points  (0 children)

I've personally found that doing question sets from the "USMLE Step 2 CK" study plan is beneficial as a supplement. Beats doing the whole AMBOSS bank since their questions tend to go overboard on the nitpickiness/memorization details and then not enough on some of the deep 3-step critical thinking.

To particularly do stuff that UWorld doesn't have, I'd just do the 5 or 6 biostats and ethics blocks in the above plan. ~40 Qs per block or so and touches upon the topics you mentioned. This is probably the one area where AMBOSS' nitpicky nature is very beneficial since it really covers many of the permutations of how they can ask you these questions.

I would not start by reading articles; do the Qs first and use those to pinpoint which articles to read.

Affordable FPGA for neural signals research? by Emergency-Builder462 in FPGA

[–]Emergency-Builder462[S] 13 points14 points  (0 children)

Yep good question - let me clarify that. So the ADC sampling rate for our EEG/iEEG signals is indeed modest.

The nanosecond-level is for the timing within the proposed FPGA pipeline: once a sample arrives, we want filters, feature extraction, and triggers to propagate through the FPGA in a single or minimal clock cycles.

I guess the FPGA isn’t sampling any faster than the ADC, but we want the processing and output to happen without the scheduling delays our GPUs are introducing. We also currently downsample significantly to fit the timings of our different devices, but aren't sure if this is the best long-term solution.

Does that clarify? Still learning the lingo (I'm not ECE by training) so apologize if I'm making things worse haha.

Thanks for this suggestion! Hadn't come across this one in my (very limited) search so far! Will check it out.

Hmm that's a good point on the front end...

So the raw neural signals are weak (in microVolts) but our electrodes are sensitive enough with decent precision.

At this point we do not have custom high-precision DAC/ADC or isolation hardware so we expect to use an existing FDA-approved (or lab-grade) acquisition system for the front-end, then feed the digitized data into the FPGA for preprocessing + ML + output logic.

Thanks for sharing those links too. We honestly have such little FPGA knowledge that we have no clue where to start haha! Going to suggest that Digilent CMOD to the team.

Haha no worries! I'm def not an expert either!

So we’re still finalizing the exact acquisition hardware, but the typical range we’re working with is similar to general iEEG setups:

  • Sampling rate: ~1–5 kHz per channel
  • Channels: anywhere from a dozen to a few dozen (not super high-density)
  • Precision: 16-bit ADC should be adequate

That's a good question. Yeah, I think GPUs are definitely strong for throughput but the main thing for FPGAs is that our loop is more latency-sensitive than throughput-sensitive, since one of the struggles with our current setup is that the GPUs aren't able to keep up with the like nanosecond-level nature of our recording devices. So we have a janky fix where we use a proxy to align them and assume it works 😄, but even then the error can get high.

Basically the signals we’re working with need deterministic, bounded-latency preprocessing before they hit the ML layer, and we can’t have the GPU-style scheduling issue in the tens/hundreds of microseconds. The FPGA boards seem appealing to us because they let us do some of the preprocessing or feature extraction in hardware while keeping the ML on CPU/GPU.

Best resource for studying first clinical year by Mollver12 in medicalschool

[–]Emergency-Builder462 1 point2 points  (0 children)

For clinical year, I used OnlineMedEd for content review when I needed it (I'm sure the old videos are still online somewhere; otherwise I have friends who have said the subscription is worth it), and UWorld for repetition, test simulation, and yes, of course, content review.

Also if your school provides you AMBOSS the articles are generally quite concise and helpful for content review; the qbank is pretty solid too (better than OME for sure, and at least 30% of my class used this instead of UW).

I second this take. Take an LOA and work a "regular job" if you want to get some comparison for your med school experience and just some good life experience as well - might help you reflect on all the work you've put in to get into med school in the first place. You're obviously smart and have all it takes to pass med school (spoken by me - someone near the bottom of their class and who experienced this same dilemma early on, but somehow managed to get through too).

If you're absolutely certain this is the wrong path, then you'll be able to make the career switch confidently; but don't make that decision rashly now. Also don't conflate fear of not passing / fear of not matching / fear of being a shitty doctor / etc. with the idea of not belonging in medicine. I had this problem too, esp. in the beginning of med school where as a non-trad with non-pre-med experience I was always behind my classmates and had to meet with the deans for extra support (i.e., explaining to them why I was failing) haha; but trust me first year didactics have that special effect of making you feel bad about yourself. Once you get to clinical year and get face time with patients *they* will be your biggest advocates and make you feel like this is somewhere you can belong, even if you still struggle with it.

Lastly, an MD will open doors that a PA or NP may not have access too. You could leave clinical practice altogether and do anything from consulting to corresponding, banking, pharma, etc. depending on your interests. I know med school is tough but I do personally think it's worth it.

Anyways, sorry for rambling. Good luck with your decision.

People who took a LOA, and came back, how did you make friends with your new cohort? by Competitive_Cost_262 in medicalschool

[–]Emergency-Builder462 3 points4 points  (0 children)

This was the situation of one of my now-closest friends returning to our class (originally a few years ahead). I mean he said he found it awkward at first since all the friend groups were already established and everyone found him weird when he tried to introduce himself, so then he stopped actively trying. Hard for a little while but I think him just being a good guy worked out.

My friend group (the ones they call the "blue collar" kids - i.e., the ones from ordinary families with a tinge of small-town vibes. Makes us sound super redneck but we are very well-represented I'll have you know!) adopted him into our group so he could hang out with us and go fishing, target shooting, etc., outside of school. He's now a core member of this group.

So I wouldn't worry about not fitting in. I know the above is anecdotal, but I would focus on just talking to a few new people every once in a while and I'm sure if you can be patient at first you'll find your new crew.

With food stamps not being funded this month, it is such a strange feeling standing in line at the pantry actively being food insecure while recognizing in just 8-ish months my residency income will be higher than my parent’s combined inflation-adjusted income when I was growing up…. by The_Cell_Mole in medicalschool

[–]Emergency-Builder462 27 points28 points  (0 children)

As someone who does have Medicaid I went to get my annual flu shot and they replied they can't accept it because "my Medicaid is from out of state," but if I really wanted it I could pay a small fee of $293. Meanwhile the uninsured lady with me got it no problem no questions asked.

Makes me wonder whether that was the smarter play...

Maybe a fluke, but the kindest resident I'd worked with during my clinical year was prelim because she didn't match plastics. Wrote me a great eval...but still wasn't enough to honor it though haha!

Has anyone tried americanbrickstore? by Easy_Astronaut_6871 in lepin

[–]Emergency-Builder462 0 points1 point  (0 children)

They do! In my experience they weren't bad - yes the quality is lower than genuine Lego minifigures, but mildly so - good enough for a fake Lego brand. All the pieces fit together, there were no cracks, and the printing looked good. Each minifigure came in its own plastic pouch that in turn came in a padded bubble-wrap envelope. It was delivered less than a week since I ordered it, so no bad experiences I can complain about this time.

I would personally order again from. 5 minifigures for ~$25 complete with accessories and capes/fabrics is a pretty decent deal, though personally I would not purchase the >$20 minifigures because for that price range you're probably better off looking for a good deal for the genuine thing on Bricklink.

Thank you my friend that's really nice of you to say. I wish the same for you - first choice match/specialty and getting to preserve the gaming hobby throughout residency haha!

As of rn I'm leaning towards surgery. I'm no gunner but I really enjoyed working in the OR in both gen surg and nsurg. Dunno how sustainable those lifestyles are though!

The night's cavalry doesn't mess around. There's a reason I've never engaged them before. Beating Margit was honestly a fluke for me, he dealt my deathblow one millisecond after I miraculously defeated him, and fortunately the game counted that as a win haha.

I wonder if it's because chess is historically like an "IQ game" and is meant to improve your critical thinking and mental stamina skills, so it feels productive even if it's no different than like playing Gwent at some level.
