Journal ArticleDOI
Speed of processing in the human visual system.
TL;DR: The visual processing needed to perform this highly demanding task can be achieved in under 150 ms, and ERP analysis revealed a frontal negativity specific to no-go trials that develops roughly 150 ms after stimulus onset.
Journal ArticleDOI
Speed of processing in the human visual system
TL;DR: In this paper, the authors used a go/no-go categorization task in which subjects have to decide whether a previously unseen photograph, flashed on for just 20 ms, contains an animal.
Journal ArticleDOI
The Orbitofrontal Cortex: Neuronal Activity in the Behaving Monkey
TL;DR: Neurons in the orbitofrontal cortex of the alert rhesus monkey possess highly coded information about which stimuli are present, as well as information about the consequences of the animal's own responses, which may constitute a neuronal mechanism for determining whether particular visual stimuli continue to be associated with reinforcement, aswell as providing for the modification of theAnimal's behavioural responses to such stimuli when those responses are no longer appropriate.
Journal ArticleDOI
Spike-based strategies for rapid processing.
TL;DR: It is argued that Rank Order Coding is not only very efficient, but also easy to implement in biological hardware: neurons can be made sensitive to the order of activation of their inputs by including a feed-forward shunting inhibition mechanism that progressively desensitizes the neuronal population during a wave of afferent activity.
Journal ArticleDOI
The Time Course of Visual Processing: From Early Perception to Decision-Making
Rufin VanRullen,Simon J. Thorpe +1 more
TL;DR: It is shown that visual categorization of a natural scene involves different mechanisms with different time courses: a perceptual, task-independent mechanism, followed by a task-related, category-independent process.
