our new paper "Neural dynamics of phoneme sequencing" is now on bioRxiv!
https://t.co/jeTipPTXuf
conducted with dream-team @jrking0@AlecMarantz@davidpoeppel, we use MEG to study how phonemes are processed in continuous naturalistic speech
short summary in thread below:

Very excited about updating our preprint. We now show that our theory of plausible self-supervised learning works in spiking networks, naturally yields a local learning rule that exhibits STDP, and predicts a new form of metaplasticity of the STDP window. https://t.co/vh6Tn06s6s
“Simulations and comparison of a set of different computational models..fitted on each individual confirm that, independently of the model, decreasing dopaminergic activity does not affect learning rate but is equivalent to an increase in random exploration rate.”
Great to have this paper out! Hippocampal–prefrontal coherence mediates working memory and selective attention at distinct frequency bands and provides a causal link between schizophrenia and its risk gene GRIA1. Awesome work @alexei_bygrave! https://t.co/zFa68NhZPH
1/ Why are there so many *types* of ganglion cells transmitting visual information from the retina to the brain? In this joint work with @SamOcko, Jack Lindsey and @SuryaGanguli, we tried to answer this question through the lens of efficient coding: https://t.co/JMGlHizXs4
