Parvalbumin-Positive Basket Cells Differentiate among Hippocampal Pyramidal Cells
Open accessAbstract
CA1 pyramidal cells (PCs) are not homogeneous but rather can be grouped by molecular, morphological, and functional properties. However, less is known about synaptic sources differentiating PCs. Using paired recordings in vitro, two-photon Ca(2+) imaging in vivo, and computational modeling, we found that parvalbumin-expressing basket cells (PVBCs) evoked greater inhibition in CA1 PCs located in the deep compared to superficial layer of stratum pyramidale. In turn, analysis of reciprocal connectivity revealed more frequent excitatory inputs to PVBCs by superficial PCs, demonstrating bias in target selection by both the excitatory and inhibitory local connections in CA1. Additionally, PVBCs further segregated among deep PCs, preferentially innervating the amygdala-projecting PCs but receiving preferential excitation from the prefrontal cortex-projecting PCs, thus revealing distinct perisomatic inhibitory interactions between separate output channels. These results demonstrate the presence of heterogeneous PVBC-PC microcircuits, potentially contributing to the sparse and distributed structure of hippocampal network activity.

“However, multiple studies have challenged this view and strongly suggest that subtype specific microcircuits indeed exist, even among PVBCs (650, 656, 1230, 1252).”

“Furthermore, in the hippocampus, PVBCs evoke larger amplitude IPSCs in PCs located near s.o. than those near s.r. (i.e., deep vs. superficial) (656) (FIGURE 8A).”

“Finally, in CA1 of the hippocampus, PVBCs evoke larger IPSCs in PCs that project to the amygdala than those that project to the prefrontal cortex; conversely, PVBCs are more likely to be innervated by and receive the largest excitatory drive from prefrontal cortex projecting PCs (656) (FIGURE 8E).”

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.
