Searching for object pointers in the visual cortex – PubMed
Pointers should send facilitatory signals to the feature cells of an object, and these signals should persist across temporary occlusions and remap to compensate for image displacements caused by saccades. Here, we searched for such signals in monkey areas V2 and V4 (Macaca mulatta). We developed a new paradigm in which a monkey freely inspects an array of objects in search for reward while some of the objects are being occluded temporarily by opaque drifting strips. Two types of …https://journals.physiology.org › doi › 10.1152 › jn.00112.2020https://journals.physiology.org › doi › 10.1152 › jn.00112.2020
Searching for object pointers in the visual cortex | Journal of …
We studied the hypothetical representation of object pointers in the visual cortex. Specifically, we examined neurons in V2 and V4 to see if their activity reflects pointers rather than visual features, as commonly assumed. According to the theory sketched at the outset, a pointer activates a grouping (G) cell that in turn modulates the feature (F) cells of an object. Thus, grouping cells can be centrally (top-down) activated, as opposed to feature cells, which can be activated …https://www.researchgate.net › publication › 340657903_Searching_for_object_pointers_in_the_visual_cortexhttps://www.researchgate.net › publication › 340657903_Searching_for_object_pointers_in_the_visual_cortex

Searching for object pointers in the visual cortex.
We explored the hypothesis that the system maintains object pointers that provide permanence and stability. Pointers should send facilitatory signals to the feature cells of an object, and these signals should persist across temporary occlusions and remap to compensate for image displacements caused by saccades. Here we searched for such signals in monkey areas V2 and V4 (Macaca mulatta).

Visual search for object categories is predicted by the …
These results suggest that visual search for real-world object categories is well predicted by the stable, task-independent architecture of the visual system. New & noteworthy: Here, we ask which neural regions have neural response patterns that correlate with behavioral performance in a visual processing task.https://academic.oup.com › cercor › article › 11 › 4 › 287 › 311659https://academic.oup.com › cercor › article › 11 › 4 › 287 › 311659
Hierarchical Axis of Object Processing Stages in the Human Visual Cortex
How are objects represented in the human visual cortex? Two conflicting theories suggest either a holistic representation, in which objects are represented by a collection of object templates, or a part-based representation, in which objects are represented as collections of features or object parts.https://www.pnas.org › doi › 10.1073 › pnas.2115302119https://www.pnas.org › doi › 10.1073 › pnas.2115302119
Texture-like representation of objects in human visual cortex
This suggests that visual cortical responses, across distinct functional and anatomical areas including early visual cortex (V1, V2, V3, hV4), ventral temporal cortex (mFus, pFus, CoS, VMV, VVC, PIT), and lateral occipital cortex (LO, IOG, TOS) do not preferentially represent the natural arrangement of object features relative to scrambled arrangements containing the same complex visual features, which suggests that representations in category-selective regions of the human visual …https://www.nature.com › articles › 26475https://www.nature.com › articles › 26475
