TLDR
Whereas receptive field tuning properties reflect feedforward processing, modulations evoked by horizontal and feedback connections may reflect the integration of information that underlies perception.About:

Journal ArticleDOI
The distinct modes of vision offered by feedforward and recurrent processing.
TL;DR: An analysis of response latencies shows that when an image is presented to the visual system, neuronal activity is rapidly routed to a large number of visual areas, but the activity of cortical neurons is not determined by this feedforward sweep alone.
Journal ArticleDOI
Recognizing emotion from facial expressions: psychological and neurological mechanisms.
TL;DR: Investigations are being extended to nonhuman primates, to infants, and to patients with psychiatric disorders, to elucidate some of the mechanisms behind recognition of emotion from facial expressions.
Journal ArticleDOI
Why visual attention and awareness are different
TL;DR: In this paper, the authors present definitions of visual attention and awareness that clearly distinguish between the two, yet explain why attention and attention are so intricately related, and why there seems more overlap between mechanisms of memory and awareness than between those of attention.

Alpha and gamma oscillations characterize feedback and feedforward processing in monkey visual cortex.

TL;DR: It is concluded that high- and low-frequency oscillations provide markers of feedforward and feedback processing, respectively.
Journal ArticleDOI
Fast Backprojections from the Motion to the Primary Visual Area Necessary for Visual Awareness
TL;DR: Trans transcranial magnetic stimulation is used to probe the timing and function of feedback from human area MT+/V5 to V1 and found its action to be early and critical for awareness of visual motion.

Distributed Hierarchical Processing in the Primate Cerebral Cortex
TL;DR: A summary of the layout of cortical areas associated with vision and with other modalities, a computerized database for storing and representing large amounts of information on connectivity patterns, and the application of these data to the analysis of hierarchical organization of the cerebral cortex are reported on.

Receptive fields and functional architecture of monkey striate cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: The striate cortex was studied in lightly anaesthetized macaque and spider monkeys by recording extracellularly from single units and stimulating the retinas with spots or patterns of light, with response properties very similar to those previously described in the cat.
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
Neural mechanisms of spatial selective attention in areas V1, V2, and V4 of macaque visual cortex
TL;DR: The role of attention was examined in areas V1, V2, and V4 of macaque monkeys with the use of a behavioral paradigm in which attention was directed to one of two stimulus locations and it was found that the cell's response was strongly influenced by which of the two stimuli was attended.
Journal ArticleDOI
Multimodal representation of space in the posterior parietal cortex and its use in planning movements
TL;DR: A review of recent studies showing that the encoding of intentions to make movements is also among the cognitive functions of the posterior parietal cortex is reviewed.
