Recent data have supported the hypothesis that, in primates, the primary visual cortex (V1) creates a saliency map from visual input. The exogenous guidance of attention is then realized by means of monosynaptic projections to the superior colliculus, which can select the most salient location as the target of a gaze shift. V1 is less prominent, or is even absent in lower vertebrates such as fish; whereas the superior colliculus, called optic tectum in lower vertebrates, also receives retinal… Expand
Superior colliculus encodes visual saliency before the primary visual cortex
TLDR
While the response latency to visual stimulus onset was earlier for V1 neurons than superior colliculus superficial visual-layer neurons (SCs), the saliency representation emerged earlier in SCs than in V1, which is consistent with the hypothesis that SCs neurons pool the inputs from multiple V1 neuron to form a feature-agnostic saliency map, which may be relayed to other brain areas.

Bidirectional encoding of motion contrast in the mouse superior colliculus
TLDR
It is shown that neurons in the mouse superior colliculus (SC) encode visual saliency by detecting motion contrast between stimulus center and surround, suggesting feature-specific saliency encoding in themouse SC. Expand
Visual Cortex Gains Independence from Peripheral Drive before Eye Opening
TLDR
It is observed that the quality of retinal activity transfer to the thalamus and superior colliculus does not change across the first two postnatal weeks, suggesting that intrinsic cortical activity competes with signals from the sensory periphery as the cortex matures. Expand
The neural instantiation of a priority map.
TLDR
It is proposed that the lateral intraparietal area (LIP) of posterior parietal cortex provides a simple representation of attentional priority, which remaps across saccades, so that there is an apparent allocentric map in a region with retinocentric encoding scheme. Expand
Functional modulation of primary visual cortex by the superior colliculus in the mouse
TLDR
The functional role of SC is demonstrated in modulating V1 responses through an excitatory pathway via the dorsal lateral geniculate nucleus through which calculations of visual saliency in the superior colliculus can influence tuning in the visual cortex via a tectogeniculate pathway. Expand
Bottom-up saliency and top-down learning in the primary visual cortex of monkeys
TLDR
V1’s early responses are directly linked with behavior and represent the bottom-up saliency signals, likely serving as the basis for making the detection task more reflexive and less top-down driven. Expand
Modeling Bottom-Up and Top-Down Attention with a Neurodynamic Model of V1
TLDR
This work proposes to build a unified model that could be extended to predict and understand distinct perceptual processes in which V1 is responsible, and shows how temporal and spatial characteristics of inhibition of return can improve prediction of saccades, as well as how distinct search strategies predict attention at distinct image contexts. Expand
Modeling bottom-up and top-down attention with a neurodynamic model of V1
TLDR
Results show that the model outpeforms other biologically inspired models of saliency prediction while predicting visual saccade sequences with the same model, as well as how distinct search strategies can predict attention at distinct image contexts. Expand

The optic tectum of birds: mapping our way to understanding visual processing.
TLDR
This paper reviews the connectivity and function of the optic tectum (homolog of the superior colliculus) in birds and highlights the retinotopic projections and functional topographic projections that it has with the nucleus rotundus and entopallium. Expand
Mouse Primary Visual Cortex Is Used to Detect Both Orientation and Contrast Changes
TLDR
It is found that suppressing activity in V1 substantially impaired performance in visual detection tasks and depended on the retinotopic position of the visual stimulus, confirming that the effect was due to the specific suppression of the visually driven V1 neurons. Expand

It is demonstrated that OT neurons in the barn owl systematically encode the relative strengths of simultaneously occurring stimuli independently of sensory modality, setting the stage for potential winner-take-all target selection for gaze and attention. Expand
Orientation columns in the mouse superior colliculus
TLDR
It is shown that cells with similar orientation preferences form large patches that span the vertical thickness of the retinorecipient layers in the mouse superior colliculus, a finding with implications for behavioural responses mediated by this brain centre. Expand
Computational modelling of visual attention
TLDR
Five important trends have emerged from recent work on computational models of focal visual attention that emphasize the bottom-up, image-based control of attentional deployment, providing a framework for a computational and neurobiological understanding of visual attention. Expand

This review will concentrate on sensory and motor inputs to the superior colliculus, on its internal circuitry, and on its connections with other brainstem gaze centers, as well as its extensive outputs to those structures with which it is reciprocally connected. Expand

It is proposed that the visual signal through V1 is necessary for deliberate control of saccades, and that decision threshold for saccade initiation was lowered. Expand
