Sensory processing: who's in (top-down) control?


Ruff, Christian C (2013). Sensory processing: who's in (top-down) control? Annals of the New York Academy of Sciences, 1296(1):88-107.

Abstract

A major aim of Jon Driver's research was to identify principles by which the brain selects behaviorally relevant stimuli or thoughts for in-depth processing. His insights have shaped neurobiological models of selective attention that highlight top-down modulations of sensory cortex as a neural substrate of adaptive behavioral control. In this paper, I review research on the characteristics and neural origins of such top-down modulations. The studies reviewed show that neural processing in sensory cortical areas can be biased toward behaviorally relevant stimuli and thoughts by feedback projections from frontal and parietal brain areas. Such modulatory influences are similarly present for judgments about external sensory information (during attention) or internal representations (during imagery and short-term memory), potentially reflecting common neural mechanisms that enhance sensory processing of relevant neural signals. How such top-down control processes may ultimately be guided by motivational brain systems is a topic of current debate, for which Jon Driver's work will continue to provide important inspiration.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
