1/3) This may be a very important paper, it suggests that there are no prediction error encoding neurons in sensory areas of cortex:

I personally am a big fan of the idea that cortical regions (allo and neo) are doing sequence prediction.

But...

Sensory responses of visual cortical neurons are not prediction errors
Predictive coding is theorized to be a ubiquitous cortical process to explain sensory responses. It asserts that the brain continuously predicts sensory information and imposes those predictions on lo...

I'm really proud of my two graduate students, Hyein and Hayagreev, for getting this challenging and exciting project across the finish line. We reveal the state-dependent logic that underlies callosal signaling between the somatosensory cortices. www.nature.com/articles/s41...
Bilateral integration in somatosensory cortex is controlled by behavioral relevance - Nature Neuroscience
How sensory signals from both sides of the body are integrated into a single percept is not well understood. Park et al. show that callosal signaling supports the integration of bilateral tactile stim...

Happy to have contributed a chapter to this book and excellent resource!
🧪 Congrats to the editors of the new Handbook of Electrophysiology, @scimemia.bsky.social, @nwanaverbecq.bsky.social, & @ianduguid.bsky.social, as well as my past postdocs @hovywong.bsky.social (now PI at CUHK) and Aurore Thomazeau (now PI at IPMC-CNRS France) to their two chapters in this book!

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.

Across the neural hierarchy, sensory maps are thought to transition from a faithful representation of receptor space to a map weighted by learned associations. Where does this transformation occur? In our latest paper, we explore a value-based spatial transformation between cortex and midbrain.

Hi friends, If you haven't seen it already, I was part of a mess this week — about science in the United States, and about NIH research aimed at understanding things like Alzheimer's, schizophrenia, autism, and depression.

Our new paper is out in Neuron! We characterize auditory prediction errors across primary and secondary regions, to simple and complex stimuli. Deviance detection (and context) are distinct from basic adaptation -- even in a simple oddball paradigm. 1/2
