Abstract

The response of cortical neurons to a sensory stimulus is modulated by the context. In the visual cortex, for example, stimulation of a pyramidal cell's receptive-field surround can attenuate the cell's response to a stimulus in the centre of its receptive field, a phenomenon called surround suppression. Whether cortical circuits contribute to surround suppression or whether the phenomenon is entirely relayed from earlier stages of visual processing is debated. Here we show that, in contrast to pyramidal cells, the response of somatostatin-expressing inhibitory neurons (SOMs) in the superficial layers of the mouse visual cortex increases with stimulation of the receptive-field surround. This difference results from the preferential excitation of SOMs by horizontal cortical axons. By perturbing the activity of SOMs, we show that these neurons contribute to pyramidal cells' surround suppression. These results establish a cortical circuit for surround suppression and attribute a particular function to a genetically defined type of inhibitory neuron.

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

  • FS cells have low input resistance and a very fast time constant, perhaps due in part to developmentally regulated TASK-3 leak K+ channels.

    “Low input resistance, and very fast time constant perhaps due in part to the developmentally-regulated expression of TASK-3 leak K+ channels3,4”

    From GABAergic Interneurons in the Neocortex: From Cellular Properties to Circuits (2016) · cites this paper as [4]

    The 'Different size tuning of distinct neurons' section describes fast-spiking inhibitory neurons and the thin spikes of parvalbumin neurons, but does not report their input resistance or membrane time constant. Searches for TASK-3 and those electrical properties found no passage addressing developmentally regulated TASK-3 channels or the proposed explanation. (LLM, conf=0.76)

  • Sst interneurons show very little interconnectivity despite overlapping axonal and dendritic domains with other Sst cells.

    “On the other hand, Sst INs, despite having axonal plexus overlapping with dendritic domains of other Sst cells show very little interconnectivity (Adesnik et al., 2012; Dennison-Cavanagh et al., 1993; Gibson et al., 1999; Pfeffer et al., 2013)”

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

    The 'Excitation of SOMs by horizontal axons' section (page unavailable) reports little inhibition recorded in SOMs during stimulation of horizontal projections, but does not identify the source of that inhibition or measure SOM-to-SOM connectivity. Searches for SOM-to-SOM connections and overlapping axonal and dendritic domains found no passage addressing those claims. (LLM, conf=0.72)

    Experimental — accuracy not yet measured
  • SOM+ MCs in other layers receive facilitating excitatory inputs from local principal neurons in both S1 and V1.

    “SOM+ MCs in other layers are known to receive facilitating excitatory inputs from local principal neurons in both S162,63 and V129,64.”

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.
