Hugely outmanned by non-invasive methods people, I still managed to have a couple of inquisitive conversations here at #BrainStimConf and find the most interesting computation person in my life. Not too ashamed of my poster anymore:

Optogenetic stimulation in visual cortex evokes modality-specific percepts; projection-specific optogenetic stimulation of visual vortex for neuroprosthesis (I'm one of those noninvasive guys, but find this very interesting work)

Great work by @sucharit.bsky.social suggesting that one failure mode in maintaining low self-esteem is the failure to integrate experiences of high confidence into self-esteem. Would be great to develop the intervention/therapeutic potential further.

"Survey measures of metacognitive monitoring are often false" - N = 273 study examines self-reported metacognition scales vs task based measures and finds a negative correlation at best. Interoception research really needs to realise this... link.springer.com/article/10.3... #psychscisky

📣 Dear #psychsky, I know many of you are swamped with peer review requests… but it’s been quiet on my end 🤷🏽‍♂️ So, journal editors on here: I’m open to doing more peer reviewing! My expertise lies in developmental and social psychology. Feel free to dm me for my contact info 🙏🏽 #devpsyc #socialpsyc

You first.

If you're curious how a democracy transitions from a free press to state-run media, this is the kind of step you'd expect to see.

On Friday I learned my monthly Cycling Plus column has ended. As a freelancer work comes and goes, and I'm hugely grateful for the three years I had. Where a door closes, etc., so I'll be posting on Substack instead. Here's a quick post by way of introduction. It's a bit of a new adventure

Looking for any papers that report a significant increase in any effect (not motor) in systole compared with diastole. I think I have an exhaustive list but just checking that I have not missed any. If you know of any please let me know. Thanks #interoception #cardiac

Starmer has the backing of Britons to stand up to Trumpism. At the White House, he should do so | Polly Toynbee

The US voted *with* Russia against the UN resolution condemning the invasion of Ukraine and demanding a withdrawal. Utter betrayal of country, allies, and principles.

After playing a fictional member of the Resistance a long time ago, I never could have imagined it ever happening in real life, but here we are.

Read this twice. The world we know is shifting beneath our feet.

An extraordinary moment. America has publicly resigned its leadership of the free world

Applications close Friday 28th!!

Just finished rewatching all of Twin Peaks last night. Started listening to the Final Dossier audiobook today. So yes, I celebrate. Happy #twinpeaksday!

Amen to that.

Worst. Episode. EVER.

Excited to see this now out in the world! We identify a computational basis for how persistent underconfidence is maintained in the face of intact performance, finding that it is grounded in impaired updating of global self-beliefs from local metacognition www.nature.com/articles/s41... 1/N

Team Canada wins in overtime, and l’ve never been delighted with a hockey win before, ever.

🔥 Finally!! Starmer ready to offer Youth Mobility Scheme. 🙌🙌🙌

preprint updated - www.biorxiv.org/content/10.1... Each of us perceives the world differently. What may underlie such individual differences in perception? Here, we characterize the lateral prefrontal cortex's role in vision using computational models ... 1/ 🧠📈 🧠💻

❗RESEARCH OPPORTUNITIES❗ We're hiring for an ambitious @wellcometrust.bsky.social project exploring brain mechanisms of planning/inference in psychosis 🧠 Tackled at multiple scales: from single neurons to human behaviour/fMRI and neural networks. Opportunities for 1 post-doc 1 clinical fellow 👀

#neurojobs Looking for a new role as Professor in Human/Cognitive/Translational Neuroscience? @thechbh.bsky.social has great facilities, lovely people...and an open position: www.jobs.ac.uk/job/DLW735/p...

This guy just voted to confirm an anti-vaxxer responsible for a measles outbreak in Samoa as HHS Secretary. These people are Fu*king shameless

Go ahead. Let the people see you for what you are.

127 8-page submissions for #CCN2025. Abstracts look great. We had hoped for 80. CCN Proceedings appears to have launched successfully. Will yield 30-35 great papers. 🙏 to the Debbie Yee, Sneha Aenugu, and especially @jaspervdb.bsky.social and @eringrant.bsky.social

Super interesting idea that each neuron is trying to control its inputs open.spotify.com/episode/1ZoX...

Finally out 🎉 - Our new paper explores the neuroimaging and computational differences of reward anticipation in kids with and without psychotic-like experiences. Well done, Pritha Sen, for the great work!!🤩 www.sciencedirect.com/science/arti...

I'm hiring a full-time research assistant to start this Summer! The lab studies perception and cognition from infancy to adulthood using neuroimaging, behavioral, and computational approaches For more details about the lab and the position, see: vlad-lab.com/join #psychjobs #neurojobs

Research assistant position at UCL, contributing to study of the neural substrates of visual perception with 7T fMRI and MEG www.ucl.ac.uk/work-at-ucl/... via @peterkok.bsky.social @jhaarsma.bsky.social

We have an opening for a 12 month Research Assistant post, funded by an ERC grant. The postholder would help with several neuroimaging projects, including MEG and 7T fMRI. Please repost and share with anyone who may be interested. www.ucl.ac.uk/work-at-ucl/... #neuroskyence #Neuroimaging

One of our supporters shared this with us—people are getting creative tonight!

Latest blogpost on Musk/Royal Society debacle: deevybee.blogspot.com/2025/02/seve... I look at the reasons that have been given for inaction, and find them wanting. @royalsociety.org

Contra Michel et al.s' recent (2024) Letter in TICS (@matthiasmichel.bsky.social @jorge-morales.bsky.social), I argue that the episodic memory findings in aphantasia are genuine and defend the episodic memory account of aphantasia. www.sciencedirect.com/science/arti...

Good response to our recent TiCS paper on aphantasia as mental imagery blindisght. Let’s keep the discussion going.

BAMB! is happening again in 2025. Learn how to model your behavioural data, next to the beach in Barcelona! keynotes this year from @athenaakrami.bsky.social and Peter Dayan.

You are not powerless, and he is not unstoppable. Look at, and learn from, the funding freeze and how quickly he was forced to surrender.

Hi Bluesky! Glad to be here.
