Does your research involve comparing experimental conditions? Then our latest publication is for you: We developed generalized contrastive PCA (gcPCA), a tool for comparing high-dimensional datasets. 🧠📊 doi.org/10.1371/journal.pcbi.1012747
This tool was born out of necessity, here is the story. 🧵

I've been waiting some years to make this joke and now it’s real:

I conned somebody into giving me a faculty job!

I’m starting as a W1 Tenure-Track Professor at Goethe University Frankfurt in a week (lol), in the Faculty of CS and Math

and I'm recruiting PhD students 🤗

This way they can just swap the names 😅

Thank you!

The prized possessions include a can of sardines, a working air drill, and 12 ready to go glass pipettes, among so many other items that money can't buy

The spot of a past lab member usually gets scavenged by other members rather quickly, on a first-come, first-served basis. This time, I'm separating my most valuable possessions and making a raffle so that the other lab members have equal opportunities in the scavenging

Stoked to see this paper finally out!

It answers two big questions: where visual objects are encoded in the brain, and how head-direction cells get oriented using visual landmarks.

Super fun collaboration with @mace-lab.bsky.social and Stuart Trenholm.

Thrilled to share that our work is now published in Science! ✨

We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭

Gero's talk at the last SFN about this has been the most mind-blowing seminar in neuroscience I've seen.

The Transmitter @thetransmitter.bsky.social · 29d

Sleep might be an “inescapable consequence” of aerobic metabolism, new findings in fruit flies suggest.

By @vcallier.bsky.social

Mitochondria set ‘ancient’ metabolic thermostat for sleep in flies, separate from circadian rhythms

During waking hours, a specialized set of sleep neurons in the fly brain accumulates reactive oxygen species, which eventually trigger sleep to clean up and repair the damage they do.

Last week I defended my Ph.D. It's a bittersweet moment to say goodbye to a project that has shaped my life for years. Time to look toward what's next.
To everyone who's been part of this journey, thank you.
I also got this slick katana with a manifold engraved in it, from @lukesjulson.bsky.social

A katana sword is displayed on a wooden table. It has a black blade and a dark blue handle wrapped with cord. The scabbard is black with silver detailing, and engravings reading 'Eliezyer Fermino de Oliveira, PhD July 31, 2025' and a manifold are visible along the blade.

A dream coming true. Read this great thread by Ralph focusing on our study of New York Rats.

Look at those cute NYC rats running around :D

I previously noticed that to decode body movements from V1 superficial layers required much more neurons (>600) than my recordings of deep layers (~200). It's great to see a head-to-head comparison

Matteo Carandini @carandinilab.net · Jul 18

A new study led by @timothysit.bsky.social reveals that different layers of mouse V1 integrate visual and non-visual signals differently.

Activity is dominated by vision (or spontaneous fluctuations) in L2/3 and by movement in L5. This leads to different geometries.

I've been writing my thesis and I don't think it's as bad as people make it to be. Honestly, it feels rewarding at times

Thrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions. doi.org/10.1038/s415...

#neuroskyence folks: as my postdoc grant is running out soon, I am looking for new opportunities in systems neuroscience!

Keywords: patch clamp ephys, opto, mouse behavior, (in vivo) voltage imaging. Would love to return to the Basal Ganglia.

Sharing appreciated, and happy #FluorescenceFriday !

The most interesting part IMO is that the remote representations were increased only outside SWR, suggesting SWR is less controllable (activity set by an attractor?).

Eliezyer de Oliveira @eliezyer.bsky.social · May 8

Exciting paper from Loren Frank’s lab (www.cell.com/neuron/fullt.... Rats can evoke remote hippocampal representations using neurofeedback. The representations do not travel the whole spatial trajectory but rather teleport directly to the target site.
