Abstract

Electrical stimulation of visual cortex can produce a visual percept (phosphene). We electrically stimulated visual cortex in humans implanted with subdural electrodes while recording from other brain sites. Phosphene perception occurred only if stimulation evoked high-frequency gamma oscillations in the temporoparietal junction (TPJ), a brain region associated with visual extinction and neglect. Electrical stimulation of TPJ modified the detectability of low-contrast visual stimuli.

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

  • The superior temporal sulcus and temporoparietal junction receive convergent input from multiple sensory domains and play important roles in integrating that information.

    “Two of the presumptive brain regions mediating ToM function, the STS and TPJ (see above), receive convergent input from a variety of sensory domains and have been shown to play important roles in the integration of this information (Beauchamp et al., 2012; Downar et al., 2000, 2001; James et al., 2011; Shulman et al., 2003; Stevenson et al., 2007; Stevenson and James, 2009).”

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.
