Abstract

Most mental processes consist of a number of processing steps that are executed sequentially. The timing of the individual mental operations can usually only be estimated indirectly, from the pattern of reaction times. In vision, however, many processing steps are associated with the modulation of neuronal activity in early visual areas. Here we exploited this association to elucidate the time course of neuronal activity related to each of the self-paced mental processing steps in complex visual tasks. We trained monkeys to perform two tasks, search-trace and trace-search, which required performing a sequence of two operations: a visual search for a specific color and the mental tracing of a curve. We used multielectrode recording techniques to monitor the representations of multiple visual items in area V1 at the same time and found that the relevant curve as well as the target of visual search evoked enhanced neuronal activity with a timing that depended on the order of operations. This modulation of neuronal activity in early visual areas could allow these areas to (1) act as a cognitive blackboard that permits the exchange of information between successive processing steps of a sequential visual task and to (2) contribute to the orderly progression of task-dependent endogenous attention shifts that are driven by task structure and evolve over hundreds of milliseconds.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Early visual areas may serve as a dynamic ''blackboard'' that supports information processing during both bottom-up and top-down processes.

    “These findings provide empirical support for the notion that visual cortex acts as a blackboard that is used during both bottom-up stimulus processing and top-down internal generation of mental content.”

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.
