How does the #brain maintain stable sound representations sound despite variable background noise? This study by Omedas & @rswilliamson.bsky.social identifies a functional division across #auditory cortex layers, linking noise-invariance to deep-layer pathways. #AcademicSky plos.io/45a1TRI

Whooooooo - congratulations to the indomitable @meenakshiasokan.bsky.social!!!!!!
We are thrilled to announce the 2026 Zara Weinberg Leading Edge Fellows! 40 remarkable postdocs pursuing transformative research in biological/biomedical sciences. This is the 7th Leading Edge cohort and we are so excited to welcome them! www.leadingedgesymposium.org/fellows/
Excited to share a new paper from our lab, just in time for Easter, where we characterize how arousal modulates different excitatory cell-types in the auditory cortex! www.science.org/doi/10.1126/...
Pupil-linked arousal heterogeneously modulates cell-type–specific sensory processing
Two-photon imaging and pupillometry reveal how arousal modulates excitatory neuron subtypes in auditory cortex.

Excited to share some new work from my lab, where we rigorously characterize differences between L5 and L6b extratelencephalic neurons in the auditory cortex!

Yes! Beautiful new work from a dream team!
DNN models of the brain are getting bigger. Are we replacing one complicated system in vivo with another in silico? In new work, we seek the *smallest* DNN models of visual cortex, balancing prediction with parsimony. It turns out these compact models are surprisingly small! rdcu.be/e5H8G
Absolutely incredible work from the legendary SVD himself @stephenvdavid.bsky.social
Call it #ExplainableAI or just making sense of complexity. We establish a direct link between DNNs fit to #AuditoryCortex and more intuitive subspace models from the 2000s. Congrats @jeremewingert.bsky.social @satyaparida.bsky.social & Sam Norman-Haignere! #NeuroAI #SensoryNeuroscience rdcu.be/e5gLY
Just in time for Xmas! Check out some new work from my lab looking at noise-invariant representations in excitatory cell-types! Congrats to Tommy Suarez-Omedas! www.biorxiv.org/content/10.6...
Canonical cortical architecture supports the emergence of noise-invariant auditory representations
Neurons in the auditory system must represent behaviorally relevant sounds in the presence of background noise (BN) to support noise-invariant perception and behavior. Although primary auditory cortex...

Check out our posters at #SfN25 on Tuesday AM! We have lots to share and would love you all to stop by!
Dream rig acquired. My life is now going to be defined in terms of pre- and post-Boogie.
Awesome! Really beautiful stuff. Congrats all!
Super excited to share the first part of my thesis work! Perhaps how you might be able to both recognize someone’s voice *and* understand what they’re saying, we find that both social identity and vocalization category can be decoded from gerbil auditory cortex activity👂🧠 tinyurl.com/4fba6wk4
YES! GO @markhisted.org!!!!!!!!!!!!!
Federal workers are speaking out on how the Trump regime is harming Americans: "We stand here today at a moment of the greatest assault of our lifetimes on our freedoms. The US Constitution is being shredded... We are here to call on Congress to stand up and stop it." youtu.be/uw1KwIBgrCw?...
Thank you @rswilliamson.bsky.social from University of Pittsburgh for giving a wonderful seminar at @erasmusmc.bsky.social about his exciting work on #auditory #corticofugalprojections. We thoroughly enjoy the discussion and hope you had a great time in the beautiful city of Rotterdam.
Really excited to share the latest work from my lab, where we identify how distinct cortical projections differentially encode sensory category and choice.
A cortical output channel for perceptual categorization
Perceptual categorization allows the brain to transform diverse sensory inputs into discrete representations that support flexible behavior. Auditory cortex (ACtx) has been implicated in this process,...

New work from the lab highlighting the differential effect of arousal on distinct excitatory projections!

Go work with Pierre! He is the business!
(Plz repost) I’ve been receiving some good news lately and will be hiring at all levels to expand the lab. Please get in contact if you are interested in reinforcement learning, neural plasticity, neural circuit dynamics, and/or hearing rehabilitation. pierre.apostolides @ umich .edu Tyvm
Beautiful new work from @anbuhlk.bsky.social! Go join her new lab!
Excited to share my latest work just out in @pnas.org! This NIH MOSAIC K99-funded project identifies a top-down cortical circuit—from cingulate to auditory cortex—that supports auditory perceptual performance in challenging listening conditions: www.pnas.org/doi/10.1073/...

Incredible new work from the legendary @caroline-runyan.bsky.social. Congrats to all!
Check out our new paper, that reveals both the striking generality of cortical circuit organization, but also what we think are key differences in the scales of local excitatory and inhibitory networks across cortical areas. www.jneurosci.org/content/45/1...
Congrats @audreydrotos.bsky.social and @robertsneuro.bsky.social!!!!!! Happy that we got a chance to contribute!
Our new work investigating multiplexing and mixed selectivity in auditory inferior colliculus neurons is up on bioRxiv 🎉 doi.org/10.1101/2025...
Happy to announce some exciting new funding from @kavlifoundation.bsky.social to investigate brain-wide projections using holographic opto with Greg Handy and Anne Takesian!

Super excited to share the first preprint from my lab, looking at auditory cortical necessity and categorical learning. This one has been cooking for a while and has really set the stage for several other ongoing projects in the lab (stay tuned)! www.biorxiv.org/content/10.1...
