Abstract

Although it has long been posited that sensory adaptation serves to enhance information flow in sensory pathways, the neural basis remains elusive. Simultaneous single-unit recordings in the thalamus and cortex in anesthetized rats showed that adaptation differentially influenced thalamus and cortex in a manner that fundamentally changed the nature of information conveyed about vibrissa motion. Using an ideal observer of cortical activity, we found that performance in detecting vibrissal deflections degraded with adaptation while performance in discriminating among vibrissal deflections of different velocities was enhanced, a trend not observed in thalamus. Analysis of simultaneously recorded thalamic neurons did reveal, however, an analogous adaptive change in thalamic synchrony that mirrored the cortical response. An integrate-and-fire model using experimentally measured thalamic input reproduced the observed transformations. The results here suggest a shift in coding strategy with adaptation that directly controls information relayed to cortex, which could have implications for encoding velocity signatures of textures.

  • Adaptive modification of the window of opportunity has been suggested to be important for switching from detecting the presence of a sensory stimulus to discriminating between stimuli.

    “Interestingly, this adaptive modification of the window of opportunity has been suggested to be an important component allowing the switching from detecting the presence of a sensory stimulus to discriminating between different stimuli (Wang et al., 2010)”

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.
