Just a teaser: The superficial layers alone showed the left hemisphere dominance in envelope encoding, which is thought to be important in semantic vs prosodic language processing in humans. We speculate this could be a common aspect of encoding in primates (human and nonhuman).

Understanding how different intracortical circuits encode envelope fluctuations can lend insight into how information about communication signals is transformed across the cortical hierarchy. Check out the paper to see what we found: www.biorxiv.org/content/10.1...

Rapid envelope fluctuations form part of the foundation of our auditory perception. They allow us to differentiate the pitch of people’s voices, perceive speech as categorically different from music, etc.

New work from Yoshi Kajikawa and myself! 🐒 🦻

We measured sound envelope encoding in different cortical layers across the nonhuman primate auditory cortical hierarchy for the first time. Thread below.

Great piece by @neuralreckoning.bsky.social with a nice hopeful vision of the future of science, as always
