Abstract

In the mammalian neocortex, an area typically receives inputs from, and projects to, dozens of other areas. Mechanisms are needed to flexibly route information to the right place at the right time, which we term 'pathway gating'. For instance, a region in your brain that receives signals from both visual and auditory pathways may want to 'gate in' the visual pathway while 'gating out' the auditory pathway when you try to read a book surrounded by people in a noisy café. In this review, we marshall experimental and computational evidence in support of a circuit mechanism for flexible pathway gating realized by a disinhibitory motif. Moreover, recent work shows an increasing preponderance of this disinhibitory motif from sensory areas to association areas of the mammalian cortex. Pathway input gating is briefly compared with alternative or complementary gating mechanisms. Predictions and open questions for future research on this puzzle about the complex brain system will be discussed.

  • Animal studies using proxies for consciousness have highlighted certain neuron classes, layer-spanning elements, and cortical circuits.

    “work in animal models using methods that can serve as proxies for consciousness (e.g. anesthesia, perceptual detection) has emphasized the importance of certain classes of neurons [7–9], layer-spanning neuronal elements [10], and cortical circuits [11].”

    From Testing circuit-level theories of consciousness in humans (2026) · cites this paper as [11]

    The section ‘A disinhibitory motif’ (page unavailable) reviews evidence from behaving mice for a cortical circuit involving distinct interneuron types, supporting the part attributed to [11] about cortical circuits. It does not characterize those experiments as using proxies for consciousness, such as anesthesia or perceptual detection. The neuron-class and layer-spanning claims are attached to other citations, not this one. (LLM, conf=0.78)

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.
