  • representations
  • Some studies have reported strong age-dependent cortical thinning in portions of V1 that likely correspond to peripheral visual representations, while there is less evidence of substantial cortical thinning in central V1. (frontiersin.org)
  • These analyses revealed age-dependent cortical thinning specific to peripheral visual field representations in anterior portions of V1, but did not provide evidence for age-dependent cortical thinning in other portions of V1. (frontiersin.org)
  • lateral
  • Visual information coming from the eye goes through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex. (wikipedia.org)
  • Each hemisphere's V1 receives information directly from its ipsilateral lateral geniculate nucleus that receives signals from the contralateral visual hemifield. (wikipedia.org)
  • Importantly, object-selective cortical regions such as the lateral occipital cortex show such attenuation even though the repeated objects may differ in their sizes, orientations, or perceived depths, revealing cue-independent object representations ( 15 , 16 ). (pnas.org)
  • Layer 4, which receives most visual input from the lateral geniculate nucleus (LGN), is further divided into 4 layers, labelled 4A, 4B, 4Cα, and 4Cβ. (wikipedia.org)
  • ventral visual
  • Here, we report the consequences of spatiotemporally continuous vs. discontinuous motion on perceptual representations in human ventral visual cortex. (pnas.org)
  • These results indicate that spatiotemporal continuity modulates neural representations of object identity, influencing judgments of object persistence even in the most staunchly "featural" areas of ventral visual cortex. (pnas.org)
  • mammals
  • CSD is a wave of neuronal and glial depolarization, followed by long-lasting suppression of neural activity, which is easily evoked in mammals with lissencephalic ( 2 , 3 ) or folded cortex ( 4 ). (pnas.org)
  • functionally
  • Thus, functionally assessed OD can be altered in cortex by ocular imbalances substantially earlier and far later than expected. (nih.gov)
  • cognitive
  • The use of spatiotemporal continuity to determine object persistence has not only been well documented in many areas of cognitive science, but has been shown to dominate visual similarity in several contexts. (pnas.org)
  • fMRI
  • For example, presenting two identical objects in rapid succession results in an attenuated fMRI signal in several regions of visual cortex, relative to the rapid presentation of two different objects. (pnas.org)
  • area
  • Initially, a focal increase in BOLD signal (possibly reflecting vasodilation), developed within extrastriate cortex (area V3A). (pnas.org)
  • In this case too, the representation is uneven: the fovea-the area at the center of the visual field-is greatly overrepresented compared to the periphery. (wikipedia.org)
