Before 👤Alan Turing's invention, people thought of #computers as individuals calculating numbers 9-5 🕘🕔. Just like "engine" referred to a 🐎 horse before the Industrial Revolution.

Technical follow-up: the interesting part of @Myndlift is that it is not just “Muse alone.” Their setup can use a separate movable electrode across 10–20 EEG sites for sqEEG-style brain mapping.

Important nuance: sqEEG means sequential EEG. It is not the same as traditional full-cap qEEG, where many channels are recorded at once. My understanding is that sqEEG collects EEG data sequentially from different scalp locations, then uses it to build brain maps under remote professional guidance.

A practical detail I also appreciate: some Myndlift kit bundles include a hard case. That matters more than it sounds—the Muse headband feels delicate, and without a case it’s awkward to store or travel with safely.

I’m also curious whether this kind of sqEEG data could eventually be combined with LORETA/sLORETA source-localization methods to improve functional interpretation—not just “which frequency band is high,” but roughly where the activity may be coming from.

For inspecting Muse signals directly, I found Mind Monitor useful: https://t.co/MNMVd1Ftq5

After a couple weeks with @ChooseMuse, I’m impressed by the idea but disappointed by signal reliability. For overnight EEG, I want clearer signal-quality history; otherwise beautiful sleep/neurofeedback summaries are hard to trust.

I tried sleeping with the Muse headband overnight, wearing it snugly, but I still seemed to lose signal more often than I expected. In the iPhone app, I couldn’t find a clear “signal quality over time” or “minutes lost” report, which would be very helpful for interpreting the sleep data.

Using Mind Monitor made the rawer side of the experience much more visible. I could see that signal quality and dropouts are not a minor technical detail—they directly affect how much confidence I can place in sleep and neurofeedback summaries.

That said, I’m still impressed by the direction of the technology. The “Digital Sleeping Pill” concept is especially interesting: adaptive audio that responds to your state and tries to help you fall asleep or return to sleep feels like a real glimpse of where consumer neurotech could go.

Muse S Athena is also interesting because it combines EEG with fNIRS, so it can look not only at brainwave activity but also blood-flow / oxygenation signals.

I’m curious to try Muse S Athena through @Myndlift too, because their platform adds guided neurofeedback, clinician-style assessment tools, and a separate movable electrode for more structured EEG mapping.

For now, I’m going back to HRV biofeedback. There is still a lot to learn there, and the signal feels more transparent to me.

What the 4 screens show:

3. a spectrogram/heatmap — to see when activity shifts across frequencies over time

4. a live spectrum snapshot — to see which frequencies are strongest right now

Still learning, but it’s amazing to see live data from my own #brain 🧠 in real time.

[Mark Vital 🇺🇦 @markvitals]

Really exciting to explore my own brain activity in real time.

Using a Muse headband (@ChooseMuse) with the Mind Monitor app to view raw 4-channel #EEG, band activity, and a live spectrogram.

Simple test: closing my eyes produces an immediate shift in the signal.

[Mark Vital 🇺🇦 @markvitals]

What the 4 screens show:

1. raw #EEG waves from 4 sensors — to see the live signal itself and spot obvious changes/artifacts

2. band power over time (delta, theta, alpha, beta, gamma) — to see which broad #brainWaves ranges rise or fall

@ChooseMuse 👋
I bought Muse S Athena with a premium subscription. I’m excited to try it.

I set it up, but my subscription is still free 🙁
I haven’t received the activation email.

I 📧 emailed support.
Please help.

[Mark Vital 🇺🇦 @markvitals]

@alexzender Thanks for sharing your experience. I also look @ recovery in my watch.

Wristwatches use sensors to measure hypothetical, average #HRV. Since the sensors are optical and far from the heart, they mostly rely on algorithms.

Chest straps like H10 measure real ECG.

[Mark Vital 🇺🇦 @markvitals]

l've been using #HRV #biofeedback for a month and I'm impressed.

HRV, heart rate variability, correlates with the sympathetic SNS and parasympathetic PNS nervous systems. It predicts anxiety, depression, and hyperarousal.

My routine is: 🏃run 😮‍💨breathe 🧘measure

#keepTraining

[Mark Vital 🇺🇦 @markvitals]

I use Polar H10 chest strap + @EliteHRV app for #biofeedback.

I run 20 min, 3-4 times a week 🏃

I practice 5 min deep calm
breathing: short inhale - nose, long exhale - mouth, 4-8-1 pace 😮‍💨💨

I do daily 2.5 minute baseline HRV measurements called "morning readiness" 🧘

[Mark Vital 🇺🇦 @markvitals]

I’ve been using @EliteHRV and @kubiosHRV apps for measuring "morning readiness" #HRV biofeedback #baseline. I use Polar H10 chest strap sensor.
Why are the scores are so different? Does the algorithm difference cause this?

[Mark Vital 🇺🇦 @markvitals]

I’ve been using #AI and #LLMs for communication more responsibly lately, especially with a low temperature setting in @Apple writing tools. This helps me achieve consistent and quasi-predictable results.

@alexzender @X Just reflecting — moving from enterprise & SaaS software and #informationDesign into #embedProgramming, #microcontrollers, BCI and biosignal processing feels like a leap. At my age I sometimes feel “old but not obsolete,” but curiosity keeps me exploring

[Mark Vital 🇺🇦 @markvitals]

@alexzender @X Good job, that’s quite a milestone!

Have you thougjt about👨‍💻low/embed programming, 🤖robotics and 🧠 BCI interfaces to combine with AI?

I would like to hack my own #neuroFeedback device one day.

[Anna Vital @annavitals]

my kindergartener came home with cupcakes full of sprinkles. What artificial dyes are actually common vs just talked about? The data didn't exist. So I tracked 609 food additives across 817K+ products. The awareness gap surprised me ↓ https://t.co/Djg5ue00YJ

[Mark Vital 🇺🇦 @markvitals]

@alexzender Very cool idea! Embedding an interactive playground right in the docs makes it so much easier for users to explore and connect MCP servers. Excited to see this in action 👏

[Mark Vital 🇺🇦 @markvitals]

@leonovco Thanks for the explanation!
I didn’t know it was already possible.

Hallucinations on questions like model context window size were a problem for me a while ago.

@ghaffarellis @annavitals thank you, will look into this

[Mark Vital 🇺🇦 @markvitals]

@emotiv Makes sense!
While I’m not planning to use it for #meditation, I’m exploring it for remote #therapy.
Do you have a list of neurofeedback software, platforms, or APIs that are compatible with the FLEX and EPOC X devices?
Thanks in advance!

[Mark Vital 🇺🇦 @markvitals]

@emotiv Can Epoc X 14 channel EEG headset and Epox Flex 32 ch. be used as at home #neuroFeedback devices?
Are there any platforms that support brain training with Epoc?
