Abstract

We measured the timing, areal distribution, and laminar profile of fast, wavelength-insensitive and slower, wavelength-sensitive responses in V1 and extrastriate areas, using laminar current-source density analysis in awake macaque monkeys. There were 3 main findings. 1) We confirmed previously reported significant ventral-dorsal stream latency lags at the level of V4 (V4 mean = 38.7 ms vs. middle temporal mean = 26.9 ms) and inferotemporal cortex (IT mean = 43.4 ms vs. dorsal bank of the superior temporal sulcus mean = 33.9 ms). 2) We found that wavelength-sensitive inputs in areas V1, V4, and IT lagged the wavelength-insensitive responses by significant margins; this lag increased over successive levels of the system. 3) We found that laminar activation profiles in V4 and IT were inconsistent with "feedforward" input through the ascending ventral cortical pathway; the likely alternative input routes include both lateral inputs from the dorsal stream and direct inputs from nonspecific thalamic neurons. These findings support a "Framing" Model of ventral stream visual processing in which rapidly conducted inputs, mediated by one or more accessory pathways, modulate the processing of more slowly conducted feedforward inputs.

  • A fundamental role of the M system/dorsal stream might be to produce a low-resolution template of the visual scene that influences perceptual processes in ventral occipito-temporal cortex by allowing P pathway fine-detailed input to be used more effectively.

    “A fundamental role of the M system/dorsal stream might be to produce a low-resolution template of the visual scene that influences perceptual processes, such as categorization of natural images, object recognition, and perceptual grouping in the ventral occipito-temporal cortex, by allowing P pathway fine-detailed input to be used more effectively (3,75–80).”

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.
