NEURONAL CIRCUITS OF THE NEOCORTEX

Douglas, Rodney J., Martin, Kevan A.C.·2004·Annual Review of Neuroscience

Abstract

▪ Abstract We explore the extent to which neocortical circuits generalize, i.e., to what extent can neocortical neurons and the circuits they form be considered as canonical? We find that, as has long been suspected by cortical neuroanatomists, the same basic laminar and tangential organization of the excitatory neurons of the neocortex is evident wherever it has been sought. Similarly, the inhibitory neurons show characteristic morphology and patterns of connections throughout the neocortex. We offer a simple model of cortical processing that is consistent with the major features of cortical circuits: The superficial layer neurons within local patches of cortex, and within areas, cooperate to explore all possible interpretations of different cortical input and cooperatively select an interpretation consistent with their various cortical and subcortical inputs.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • L5 pyramidal cells are the main output neurons of the PFC.

    “We chose to study L5 cells, because these are the main output neurons of the PFC (Douglas and Martin, 2004).”
  • The relative homogeneity of the two largest neuronal structures (cerebellar cortex and cortex) is striking and suggests an evolutionary expansion of a canonical cortical blueprint.

    “the relative homogeneity of the two largest neuronal structures, with ~69 billion (cerebellar cortex) and ~16 billion (cortex) neurons out of the 86 billion neurons in the human brain33, is striking and suggests an evolutionary expansion of a canonical cortical blueprint34.”
  • Layer 4 receives most thalamocortical input and has a prominent role in initial sensory processing.

    “Layer 4 receives the vast majority of thalamocortical input, and so it plays a prominent role in the initial processing of sensory information (Douglas and Martin, 2004).”

  • The concept of modular organization of cortical architecture dates back more than four decades.

    “The concept of ‘modular organization’ of cortical architecture dates back more than four decades52,53,54.”
  • The communication element definition of neuron types should facilitate the delineation of higher-level modular organization of neural circuit architecture by clarifying the developmental genetic basis of elemental building blocks.

    “Thus, the communication element definition of neuron types should facilitate the delineation of higher-level modular organization of neural circuit architecture24,53 by clarifying the developmental genetic basis of elemental building blocks.”

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.
