Abstract

We have previously shown that some neurons in extrastriate area MT are capable of signaling the global motion of complex patterns; neurons randomly sampled from V1, on the other hand, respond only to the motion of individual oriented components. Because only a small fraction of V1 neurons projects to MT, we wished to establish the processing hierarchy more precisely by studying the properties of those neurons projecting to MT, identified by antidromic responses to electrical stimulation of MT. The neurons that project from V1 to MT were directionally selective and, like other V1 neurons, responded only to the motion of the components of complex patterns. The projection neurons were predominantly “special complex,” responsive to a broad range of spatial and temporal frequencies, and sensitive to very low stimulus contrasts. The projection neurons thus comprise a homogeneous and highly specialized subset of V1 neurons, consistent with the notion that V1 acts as clearing house of basic visual measurements, distributing information appropriately to higher cortical areas for specialized analysis.

  • Cells in V1 that project to MT may be regarded as local motion energy filters that are spatio-temporally separable and tuned to a specific frequency and orientation.

    “This study reveals that cells in V1 that project to MT may be regarded as local motion energy filters that are spatio-temporally separable and tuned to a specific frequency and orientation (such as the Gabor filters used here).”

    From Motion Tuned Spatio-Temporal Quality Assessment of Natural Videos (2010) · cites this paper as [35]

    The Discussion describes V1 neurons projecting to MT as local motion energy filters responsive within bandpass limits for orientation and spatial and temporal frequency. The spatial and temporal receptive-field results report frequency tuning, but our copy does not establish that these neurons are spatiotemporally separable. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Area MT receives directional information from V1 and performs more complex computations using the preliminary motion information computed by V1 neurons.

    “Area MT receives directional information from V1 and performs more complex computations using the preliminary motion information computed by V1 neurons [35].”
  • The properties of neurons in Area V1 that project to Area MT have been well studied.

    “The properties of neurons in Area V1 that project to Area MT have been well studied [35].”
  • Existing HVS-based VQA indices model only early visual processing and do not incorporate models of motion processing in Area MT.

    “All the indices mentioned above use either one or two temporal channels and model the temporal tuning of only the neurons in early stages of the visual pathway such as the retina, lateral geniculate nucleus (LGN) and Area V1 of the cortex.”

    From Motion Tuned Spatio-Temporal Quality Assessment of Natural Videos (2010) · cites this paper as [35]

    The Discussion distinguishes local motion processing in V1 from higher-order motion processing associated with MT, but it does not assess video-quality indices. Searches for temporal-channel models and such indices found no passage stating that existing indices model only early visual stages or omit MT; page numbers were not available in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Motion sensitivity of MT neurons likely arises from their direct and indirect input from V1.

    “the motion sensitivity of MT neurons likely arises from their direct and indirect input from V135”

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.
