"Everyone agrees that emergence is important, but they don’t agree on what the word should mean" arxiv.org/abs/2410.15468
What Emergence Can Possibly Mean
We consider emergence from the perspective of dynamics: states of a system evolving with time. We focus on the role of a decomposition of wholes into parts, and attempt to characterize relationships b...

Happy to see this study led by Irene Onorato finally out - we show distinct phase locking and spike timing of optotagged PV cells and Sst interneuron subtypes during gamma oscillations in mouse visual cortex, suggesting an update to the classic PING model www.sciencedirect.com/science/arti...
Distinct roles of PV and Sst interneurons in visually induced gamma oscillations
Gamma-frequency oscillations are a hallmark of active information processing and are generated by interactions between excitatory and inhibitory neuro…

A ubiquitous spectrolaminar motif of local field potential power across the primate cortex?
“Adopting the term “ubiquitous,” based on 60% of all cases, assumes that the remainder are just poorly resolved instantiations of the rule, rather than exceptions.”

I took the suggestion to join Blue sky! I'm starting my lab soon at UAB, where I'll be investigating neural mechanisms of learning, focusing on dopamine, frontal cortex, basal ganglia, and latent learning.
My website is kmcostalab.com, and I'm looking to hire at all levels, including a lab manager!

This episode of the You Are Not So Smart podcast is an interesting delve into the origin of the phrase and the psychology behind its use.
