So... hey everyone. I'm Tom.

I study neuronal oscillations and their role in attention and decision-making, mainly using MEG and brain stimulation in human volunteers.

I'm a relatively new assistant prof at @thechbh.bsky.social, Birmingham, UK.

Birmingham is a lovely place. Come visit 🙂

I'm really glad you found that place.

A deep sense of gloom descended on Birmingham‘s York Road this evening as people came out in number to mourn the absence of cars.

We’re excited to share some leadership updates at the CHBH! After three years, Dr @katjakornysheva.bsky.social stepped down this month, we're grateful to Katja for her leadership. Prof @bagshaap.bsky.social will continue as Co-Director and we welcome Prof Stephane De Brito as Co-Director into 25/26.

Holy Moly this looks like a cool opportunity.

Nice

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

Hivemind, what are your favorite platforms for scientific collaborations/networks in their early stages?

Listserv (Google Groups?) is easy but limited functionality + would prefer to move away from Google
Dedicated channels (Slack, discord) often fall out of use

Hoping to avoid platform lock-in

Bots and sockpuppets are starting to show up here.

Advice for dealing with them?

Thanks Stan. It's been... a lot.

For precisely no reason, today I'm thinking about this list of assumptions programmers - and perhaps other organisations - might have about names...

...all of which are incorrect.

Tried to use a large language model to help me find research groups at my uni studying a particular topic.

Model helpfully points me to some researchers who published a paper on said topic...

...from Australia and Germany 🤦‍♀

WHY are we incorporating these tools into our workflows?
They don't work!

Benefits of Ireland's first OPM system:

✅Enables awesome cognitive neuroscience
✅Enables awseome clinical neuroscience
✅Makes @redmondoconnell.bsky.social look rather fetching

Neuroscientists: which films do a pretty decent job in being scientifically accurate when it comes to the brain (including sci fi grounded in neuroscience)? I’m making a watchlist!

I definitely had my consciousness raised about potential harms and pitfalls by @olivia.science, @irisvanrooij.bsky.social and colleagues so would echo suggestion to take a look at their work.

Surprised no one has mentioned this:

Potential con: Was the model ethically developed? E.g. did the humans whose work was used to train the model consent to that?

If the model itself is unethical, is ones use of the model maybe unethical too?

Almost like the box people want to pigeon-hole you into is often more of a story about their own insecurities and historical grievances than anything to do with you or the work you actually do 🙃

Want to do RIFT but you're not RICH?

🚨 New preprint: Invisible neural frequency tagging (RIFT) for the underfunded researcher:
👉 www.biorxiv.org/cgi/content/...

RIFT uses high-frequency flicker to probe attention in M/EEG with minimal stimulus visibility and little distraction. Until now, it required a costly high-speed projector.

Rapid Invisible Frequency Tagging (RIFT) enables neural frequency tagging at rates above the flicker fusion threshold, eliciting steady-state responses to flicker that is almost imperceptible. While R...

Niiiice!

Looking forward to reading this. Really like the initiative to lower the entry barrier to working with this set of tools 👍👍👍

Periodic reminder that, if you had gotten <thing>, it would also have been 'well deserved'.

You didn't not get it because you don't deserve it. That's not how any of this works.
