Brain mechanisms associated with top-down processes in perception.
Perception arises through an interaction between sensory input and prior knowledge. We propose that at least two brain areas are required for such an interaction: the 'site' where analysis of afferent signals occurs and the 'source' which applies the relevant prior knowledge. In the human brain, functional imaging studies have demonstrated that selective attention modifies activity in early vis...

15 صفحه اولMechanisms for Top - down Perceptual Processing
If we are to understand how human perception occurs, then we must first identify the mechanisms that drive perception. It is commonly believed that perception is influenced by both bottom-up processes (raw sensory input), and top-down processes (expectationdriven matching). What is not fully understood is how the human mind uses expectations and assumptions to manipulate what we call conscious ...
متن کاملMechanisms of top-down attention.
Attention exhibits characteristic neural signatures in brain regions that process sensory signals. An important area of future research is to understand the nature of top-down signals that facilitate attentional guidance towards behaviorally relevant locations and features. In this review, we discuss recent studies that have made progress towards understanding: (i) the brain structures and circ...
متن کاملMechanisms of top-down facilitation in perception of visual objects studied by FMRI.
Prior knowledge regarding the possible identity of an object facilitates its recognition from a degraded visual input, though the underlying mechanisms are unclear. Previous work implicated ventral visual cortex but did not disambiguate whether activity-changes in these regions are causal to or merely reflect an effect of facilitated recognition. We used functional magnetic resonance imaging to...
