Abstract

Axo-axonic interneurons, innervating exclusively axon initial segments, and parvalbumin-expressing basket interneurons, targeting somata, dendrites, and spines of pyramidal cells, have been proposed to control neuronal activity in prefrontal circuits. We recorded the spike-timing of identified neurons in the prelimbic cortex of anesthetized rats, and show that axo-axonic cells increase their firing during tail pinch-induced brain state-activation. In addition, axo-axonic cells differ from other GABAergic parvalbumin-expressing cells in their spike timing during DOWN- to UP-state transitions of slow oscillations and in their coupling to gamma and spindle oscillations. The distinct firing dynamics and synaptic targets of axo-axonic and other parvalbumin-expressing cells provide differential contributions to the temporal organization of prefrontal networks.

  • Some reports found different excitatory input sources and in vivo responses between PV FS basket and chandelier interneurons.

    “some reports have found different excitatory input sources and in vivo responses between PV FS basket and chandelier INs”

    From GABAergic Interneurons in the Neocortex: From Cellular Properties to Circuits (2016) · cites this paper as Massi et al., 2012

    The Discussion (page unavailable) reports different in vivo firing dynamics for PV-expressing axo-axonic (chandelier) and basket cells, and the Results describe different responses to tail pinch. The Discussion infers differences in their synaptic inputs from anatomy, but does not establish different excitatory input sources for the two cell types; its suggestion about thalamic and cortical sources concerns basket-cell firing across oscillation states.

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.
