“Cortical circuitry mediating inter-areal touch signal amplification” by Ryan et al. 2023 (Simon Peron lab). https://www.biorxiv.org/content/10.1101/2023.06.06.543886v1

“we ask how topographically matched subregions of primary and secondary vibrissal somatosensory cortices (vS1 and vS2) interact during whisker touch.”

And found cortical layer 2 neurons responsible for interarea synchrony.

Switchable neural components in turtles. Perhaps not surprising but certainly extraordinary! The source paper:

"Responses of the in vitro turtle brain to visual and auditory stimuli during severe hypoxia", Ariel et al. 2023 https://doi.org/10.1242/jeb.244687

"North American pond turtles (Emydidae) are renowned for their ability to survive extreme hypoxia and anoxia, which enables several species to overwinter in ice-locked, anoxic freshwater ponds and bogs for months."

These qualities make turtles fantastic laboratory animals for neuroscience research:

On the instability (plasticity?) of cortical areas, just got reminded of this classic work:

"Somatosensory cortical map changes following digit amputation in adult monkeys", Merzenich et al. 1984 https://onlinelibrary.wiley.com/doi/abs/10.1002/cne.902240408

@Javierzsm A great reminder that the activity of a neuron matters in a different way to each target neuron type because the postsynaptic site is cell-type specific. Thanks for your work!
