What a wonderful world that would be...

The ruins of a housing complex near a main road, with an open red arrow indicating the ruins of a serpentine wall that divides the complex from the road. From Dr. Zahi Hawass/Facebook

In 2021, archaeologists announced the discovery of the 3000 year old Egyptian city called "The Dazzling Aten" near Luxor.

I want to call your attention to a brick wall under the red arrow. It's 'serpentine' & a single brick wide, separating a housing complex from the road.

Why the odd shape?

New paper from our lab! This was such a fun project to be a part of - proof that sometimes following a spurious observations down the rabbit hole leads to awesome findings.

Wouldn't it be nice if money would flow to fund research instead of funding a new layer of glossy paint? But who wants to put that on their CV "bolstered existing programs"...

Lost Lake Whistler

Keystone Neural-Immune Interactions

Symposium talk

Rock climbing preparation at Whistler Cal Cheak

Truly enjoyed the scientific and social interactions at #KSNeuroimmune2025 in Whistler. Besides presenting our work & talking science, I went rock climbing with PhD student Lynette! We also hung out (a lot) with @haesemeyerlab.bsky.social & the #zebrafish crew, including a nice hike to Lost Lake!

If you're interested in moving to Montreal for a postdoc in #NeuroAI or related topics, check out this scholarship opportunity at @fasudem.bsky.social : fas.umontreal.ca/postdoctoral...

And let me know if you'd like to chat about it.

TBH I don't think that Marr's choice reigns supreme 😉, so I don't find it anymore annoying than the general lack of clear definitions for most terms used in (neuro)science 😀

Incredibly excited and grateful to share that I’ll be starting a lab at The Ohio State University this(!) fall! My lab will study human learning and memory, with related interests in sleep, stress, and time perception. More info soon, but do get in touch if you’re interested in joining!

Oh I'm sure you are absolutely correct. I was talking in jest and should probably have added an emoji to signify that 😀

Considering the concept of granular synthesis, I assume that it means to take a meaningful story, rip out some parts and present them out of order, some even reversed

Congratulations!!

Cholinergic feedback for modality- and context-specific modulation of sensory representations The brain’s ability to prioritize sensory information is crucial for adaptive behavior, yet its mechanisms remain unclear. We investigated basal forebrain cholinergic neurons modulating olfactory bulb...

Our new paper is out in Science.

We identified a subgroup of cholinergic neurons that mediate sensory modality-specific attention. They change their funcitonal properties within secs of behavioral context change.

Congrats to Bin for the great thesis, and the team!

MIC-Drop-seq: Scalable single-cell phenotyping of mutant vertebrate embryos Pooled perturbation screens can reveal cellular regulatory networks, yet scaling these techniques for large-scale screens in animals remains challenging. To address this, we developed MIC-Drop-seq, wh...

To dissect the gene regulatory networks used to build organisms, we need Perturb-seq-like tools that work in whole animals.

For this purpose, we developed MIC-Drop-seq, a tool that couples high-throughput CRISPR in zebrafish embryos with single-cell RNAseq.

Nice, can't wait to read it when I can catch a bit of a breather!

Nice! I had wondered the same thing. I think I saw one like that close to Goodale park once.

Congratulations!!!

It is hell. ChatGPT is being used to "find hypotheses", "design experiments", "summarize research fields", "design educational content", "identify learning objectives for students." Not a world I want to be a part of but one that is being promoted in webinars here left, right and center.

I find this utterly fascinating. I walk through a park and get excited when I spot four different kinds of birds of which I'm seeing three all the time 🤣

Cardiac interoception impacts behavior and brain-wide neuronal dynamics We sought to explore the question as to whether an animal's behavior can be modified by internal physiological changes. We focused on the optomotor response, in which an animal moves in response to vi...

🎈Our latest 🪅

We know that in addition to exteroceptive mechanisms, interoceptive chemosensation is also critical for regulating physiology/behavior.

We find that an enteric neuron in worms senses ingested salts via a variant ionotropic receptor (IR like the fly IRs) to regulate salt stress. 1/n
