Cortical interneurons: fit for function and fit to function? Evidence from development and evolution

J Keijser, H Sprekeler - Frontiers in Neural Circuits, 2023 - frontiersin.org
Cortical inhibitory interneurons form a broad spectrum of subtypes. This diversity suggests a
division of labor, in which each cell type supports a distinct function. In the present era of …

Parametric control of flexible timing through low-dimensional neural manifolds

Context-invariant beliefs are supported by dynamic reconfiguration of single unit functional connectivity in prefrontal cortex of male macaques

JP Noel, E Balzani, C Savin, DE Angelaki - Nature communications, 2024 - nature.com
Natural behaviors occur in closed action-perception loops and are supported by dynamic
and flexible beliefs abstracted away from our immediate sensory milieu. How this real-world …

Learning to combine top-down context and feed-forward representations under ambiguity with apical and basal dendrites

N Islah, G Etter, M Tugsbayar, T Gurbuz… - arXiv preprint arXiv …, 2023 - arxiv.org
One of the most striking features of neocortical anatomy is the presence of extensive top-
down projections into primary sensory areas. Notably, many of these top-down projections …
