🧠 New study by Johnston, Kirschhock & Nieder (Nature Comm., 2025): Carrion #crows 🐦⬛ estimate time intervals 🕠 using abstract magnitude coding in the nidopallium caudolaterale (avian “prefrontal” #cortex). NCL neurons tuned to 1.5 s, 3 s & 6 s wait times predicted intended duration, independent of cues. This demonstrates that sophisticated timing is possible – even without a #neocortex.

What makes us #human? According to #neurobiologists it is our #neocortex. This outer layer of the #brain is rich in #neurons and lets us do abstract thinking, create art, and speak complex languages.

Direct projections from anterior cingular cortex (ACA) to the hippocampus in mouse: NOT FOUND. Questions the validity of prior work (Rajasethupathy et al. 2015 https://doi.org/10.1038/nature15389) and brings the mouse back in line with other mammalian brains where such connections have been sought but never found.
“No evidence from complementary data sources of a direct glutamatergic projection from the mouse anterior cingulate area to the hippocampal formation” by Andrianova et al. 2023 https://elifesciences.org/articles/77364
The authors use a more precise method, but also reproduce the method of the paper that reported ACA to hippocampus direct connections and conclude it was an artifact:
“the off-target retrograde labelling in this region was due to uptake of virus in axons passing through the cingulum and/or corpus callosum as well as along the path of the injection needle.”

What aspect of #trisomy21 underlies the brain disorders of #DownSyndrome? @byneuron @jenkins_paul &co show that the increased inhibitory #synapses in the #neocortex of Down syndrome mouse models is caused by raised levels of DSCAM. #PLOSBiology https://plos.io/43OjKfd

1/10) Can we find a label-free model selection algorithm in Self-supervised learning (#SSL) for #vision?
Our #NeurIPS2022 paper, α-ReQ, presents just such an #algorithm based on the structure of #representations in the #neocortex!
This is work w/ Kumar Agrawal (#Berkeley), Arnab Kumar Mondal and Arna Ghosh (#McGill/#Mila). 🧵

@tyrell_turing @AllenNeuroLab Blake, I agree w/you mostly, but I don't think it's akin to the distinction b/w #exemplars and #prototypes (e.g. category learning models). More like the #CLS model, in which #neocortex encodes input patterns with a distributed code, but #hippocampus can index specific neocortical activity patterns at specific moments so they can be reinstated later. Sort of like the implementation of SEM by @gershbrain https://psycnet.apa.org/record/2020-21913-002

By way of more introduction, another paper (open access):
'Time to Retire the Serial Papez Circuit: Implications for Space, Memory, and Attention'
https://sciencedirect.com/science/article/pii/S0149763422003025
We argue the notion of a serial Papez circuit makes no anatomical or functional sense...
Anterior thalamic nuclei and hippocampus conjointly support episodic memory
Focus should shift to how these two structures jointly interact with neocortex
