Action-based sensory encoding in spinal sensorimotor circuits

Schouenborg, Jens·2008·Brain Research Reviews

Abstract

The concept of a modular organisation of the spinal withdrawal reflex circuits has proven to be fundamental for the understanding of how the spinal cord is organised and how the sensorimotor circuits translate sensory information into adequate movement corrections. Recent studies indicate that a task-related body representation is engraved at the network level through learning-dependent mechanisms involving an active probing procedure termed 'somatosensory imprinting' during development. It was found that somatosensory imprinting depends on the tactile input that is associated with spontaneous movements that occur during sleep and results in elimination of erroneous connections and establishment of correct connections. In parallel studies it was found that the strength of the first order tactile synapses in rostrocaudally elongated zones in the adult dorsal horn in the lower lumbar cord is related to the modular organisation of the withdrawal reflexes. Hence, the topographical organisation of the tactile input to this spinal area seems to be action-based rather than a simple body map as previously thought. Far from being innate and adult like at birth, the adult organisation seems to emerge from an initial 'floating' and diffuse body representation with many inappropriate connections through profound activity-dependent rearrangements of afferent synaptic connections. It is suggested that somatosensory imprinting plays a key role in the self-organisation of the spinal cord during development.

  • Spinal reflexes and the spinothalamic pathways are engaged with peripheral interfaces while bypassed with brain interfaces.

    “Fourth, spinal reflexes (Schouenborg, 2008) and the spinothalamic pathways (important for affective touch, see McGlone et al., 2014) are engaged with peripheral interfaces while bypassed with brain interfaces.”

  • Spinal reflexes involving tactile cues are shaped during development and likely remain relatively fixed throughout adulthood.

    “For example, spinal reflexes involving tactile cues are shaped during development (Schouenborg, 2008) and likely remain relatively fixed throughout adulthood.”

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.
