TL;DR: The various top-down influences exerted on the visual cortical pathways are discussed and the dynamic nature of the receptive field is highlighted, which allows neurons to carry information that is relevant to the current perceptual demands.

Abstract: Re-entrant or feedback pathways between cortical areas carry rich and varied information about behavioural context, including attention, expectation, perceptual tasks, working memory and motor commands. Neurons receiving such inputs effectively function as adaptive processors that are able to assume different functional states according to the task being executed. Recent data suggest that the selection of particular inputs, representing different components of an association field, enable neurons to take on different functional roles. In this Review, we discuss the various top-down influences exerted on the visual cortical pathways and highlight the dynamic nature of the receptive field, which allows neurons to carry information that is relevant to the current perceptual demands.

Cognition does not affect perception: Evaluating the evidence for "top-down" effects.
Chaz Firestone,Brian J. Scholl +1 more
TL;DR: This work suggests that none of these hundreds of studies – either individually or collectively – provides compelling evidence for true top-down effects on perception, or “cognitive penetrability,” and suggests that these studies all fall prey to only a handful of pitfalls.
Random synaptic feedback weights support error backpropagation for deep learning.
TL;DR: A surprisingly simple mechanism that assigns blame by multiplying errors by even random synaptic weights is presented, which can transmit teaching signals across multiple layers of neurons and performs as effectively as backpropagation on a variety of tasks.

TL;DR: It is argued that the key principles underlying backprop may indeed have a role in brain function and induce neural activities whose differences can be used to locally approximate these signals and hence drive effective learning in deep networks in the brain.

TL;DR: It is found that attention to a stimulus in their joint receptive field leads to enhanced oscillatory coupling between the two areas, particularly at gamma frequencies, which may optimize the postsynaptic impact of spikes from one area upon the other, improving cross-area communication with attention.

Neural Mechanisms of Selective Visual Attention

TL;DR: The two basic phenomena that define the problem of visual attention can be illustrated in a simple example and selectivity-the ability to filter out un wanted information is illustrated.

TL;DR: Results suggest that rather than being exclusively feedforward phenomena, nonclassical surround effects in the visual cortex may also result from cortico-cortical feedback as a consequence of the visual system using an efficient hierarchical strategy for encoding natural images.

Oscillatory responses in cat visual cortex exhibit inter-columnar synchronization which reflects global stimulus properties.
TL;DR: It is demonstrated here that neurons in spatially separate columns can synchronize their oscillatory responses, which has, on average, no phase difference, depends on the spatial separation and the orientation preference of the cells and is influenced by global stimulus properties.
