Abstract

Kawaguchi, Yasuo. Selective cholinergic modulation of cortical GABAergic cell subtypes. J. Neurophysiol. 78: 1743–1747, 1997. Acetylcholine from the basal forebrain and γ-aminobutyric acid (GABA) from intracortical inhibitory interneurons exert strong influence on the cortical activity and may interact with each other. Cholinergic or muscarinic agonists indeed induced GABAergic postsynaptic currents in pyramidal cells by exciting inhibitory interneurons that have recently been classified into several distinct subtypes on the basis of the physiological, chemical, and morphological criteria. Cholinergic effects on GABAergic cell subtypes were investigated of rat frontal cortex by in vitro whole cell recording with intracellular staining in frontal cortex of young rats. GABAergic cell subtypes were identified physiologically by firing responses to depolarizing current pulses and immunohistochemically as containing parvalbumin, somatostatin, vasoactive intestinal polypeptide (VIP), or cholecystokinin (CCK). Carbachol (10 μM) or (+)-muscarine (3 μM) affected the activities of peptide-containing GABAergic cells with regular- or burst-spiking characteristics, but not of GABAergic cells with fast-spiking characteristics containing the calcium-binding protein parvalbumin orGABAergic cells with late-spiking characteristics. Somatostatin- or VIP-immunoreactive cells were depolarized with spike firing. CCK-immunoreactive cells were affected heterogeneously by cholinergic agonists. Larger CCK cells were hyperpolarized, followed by a slow depolarization, whereas smaller CCK cells were only depolarized. These results suggest that the excitability of cortical GABAergic cell subtypes is differentially regulated by acetylcholine. Differences in cholinergic responses suggest a distinct functional role of each GABAergic cell subtype.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In response to bath-applied agonists, the muscarinic depolarization of Sst interneurons is strong enough to produce prolonged spiking.

    “In response to bath applied agonists, the depolarization is strong enough that it is capable of producing prolonged spiking”

    From GABAergic Interneurons in the Neocortex: From Cellular Properties to Circuits (2016) · cites this paper as Kawaguchi, 1997

    The Results passage describing Fig. 3A says carbachol depolarized somatostatin-immunoreactive cells and was accompanied by spike firing in all five tested cells; the Fig. 3 caption also describes spikes during carbachol application. Our copy does not establish that the spiking was prolonged, so it supports agonist-induced firing but not that duration. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Sst interneurons exhibit muscarinic-mediated depolarization.

    “Another feature of Sst INs is a muscarinic mediated depolarization.”
  • Vip-expressing bipolar neurons are also depolarized by muscarinic agonists.

    “It has been reported that Vip-expressing bipolar neurons are also depolarized by muscarinic agonists (Kawaguchi, 1997)”

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.
