Acute and Chronic Pain Processing in the Thalamocortical System of Humans and Animal Models

Groh, Alexander, Krieger, Patrik, Mease, Rebecca A., Henderson, Luke·2018·Neuroscience

Abstract

The transmission of noxious stimuli from peripheral receptors to the cortex involves multiple central ascending pathways. While projections to areas in the brainstem and diencephalon are likely involved in mediating the immediate behavioral responses to pain, the assessment of the sensory and emotional/motivational components of pain are likely processed in parallel ascending pathways that relay in the thalamus on their way to the cerebral cortex. In this review we discuss experimental animal and human findings that support the view that a lateral thalamocortical pathway is involved in coding the sensory discriminative aspects of pain, while a medial thalamocortical pathway codes the emotional qualities of pain. In addition, we outline experimental animal and human evidence of functional, anatomical and biochemical alterations in thalamocortical circuits that may be responsible for altered thalamocortical rhythms and the persistent presence of pain following nervous system damage. Finally, we discuss advances in clinical and preclinical development of chronic pain treatments aimed at altering neural and glial function.

Statistics

Recomputing p-values needs the paper’s full text.

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?

  • The thalamocortical loop network is composed of the thalamic ventroposterolateral nucleus, the primary somatosensory cortex, and the thalamic reticular nucleus.

    “The network is part of brain pain processing and is composed of the thalamic ventroposterolateral nucleus (VPL), the primary somatosensory cortex (SSC), and the thalamic reticular nucleus (TRN) [22].”

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.
