Divisions of identified parvalbumin-expressing basket cells during working memory-guided decision making
Open accessAbstract
Parvalbumin-expressing basket cells tightly control cortical networks and fire remarkably stereotyped during network oscillations and simple behaviors. How can these cells support multifaceted situations with different behavioral options and complex temporal sequences? We recorded from identified parvalbumin-expressing basket cells in prefrontal cortex of freely moving rats performing a multidimensional delayed cue-matching-to-place task, juxtacellularly filled recorded neurons for unequivocal histological identification, and determined their activity during temporally structured task episodes, associative working-memory, and stimulus-guided choice behavior. We show that parvalbumin-expressing basket cells do not fire homogenously, but individual cells were recruited or inhibited during different task episodes. Firing of individual basket cells was correlated with amount of presynaptic VIP (vasoactive intestinal polypeptide)-expressing GABAergic input. Together with subsets of pyramidal neurons, activity of basket cells differentiated for sequential actions and stimulus-guided choice behavior. Thus, interneurons of the same cell type can be recruited into different neuronal ensembles with distinct firing patterns to support multi-layered cognitive computations.

PV+ basket cells dynamically oscillate between different states in response to neuronal activity, a process required for learning and memory in the adult brain.
“For example, PV+ basket cells seem to dynamically oscillate between different “states” in response to neuronal activity, a process that is required for learning and memory in the adult brain (Donato et al., 2013; Lagler et al., 2016).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
