I think I’ve spent too long looking at linear algebra that I thought this donut shop was celebrating the pseudo-inverse of 90 years.

WHY DOES MY MOUSE SOFTWARE INCLUDE ACCESS TO AN LLM, IN WHAT WORLD IS THAT EVEN A USEFUL IDEA?

I know these metrics can be spurious, but to see my paper is currently top of the "Most Read" section of @imagingneurosci.bsky.social is kinda wild.

Bloody hell, Elsevier are shunting generative AI summarisers into existing published papers. This example is from a 2021 NeuroImage paper doi.org/10.1016/j.ne....
We need to strenghten the barrier between carefully controlled, peer-reviwed work and spruious bullshit generators, not break it down!

Went to the Tate Modern on my last day off, and even in art all I can see is work related things. The matrix is clearly rank deficient!

Been dabbling in non-visible spectrum photography. After much trial and error I’ve finally managed to get the shot I’ve been going for.

HOT OFF THE PRESS - Back in 2019 we started asking ourselves what could you to demonstrate where werable, OPM-MEG technology could fit into naturalistic #neuroskyence.
One snag, we'd have to build the system from scratch first...
Anyway its 2025, read the paper here -> doi.org/10.1162/imag...

An obersvation on @uclofficial.bsky.social website, the job applicaiton page has mandatory fields which Facebook can supposedly access. What gives?

Chaotic travel adaptor situation arising. UK usb charger plugged into a US adaptor (with USB ports) into a power socket that also has USB. I’m sure some of those steps were unnecessary.

New Preprint! Interested in source-localising activitity from the spinal cord from OPM/SQUID measures? We built increasingly complex models to see what we can learn from them. It turns out adding the vertebrae to your model, and therfore knowing where your spinal cord is could be really important.

A couple years ago, we unveiled our first results of a system to concurrently scan the brain and spine using OPMs. I'm pleased to say its finally been published! In the Journal of Neuroscience Methods! t.co/LButItGPvn

I did a version of this on The Bad Place and inexplicably the bots took umbrage with it.
![Tweet from Twitter. It reads “is OPM a [REDACTED WEBSITE] or some band. Always special acronyms. That is open science not snobby elitism.”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:hxcq7ppiqynlruwirq6c7ifv/bafkreif35mgpslghmhso7mji2trbdhkoao7xgupwn3kfvh37tee2v72kl4@jpeg)
