Unraveling circuits of visual perception and cognition through the superior colliculus
TLDR
The superior colliculus is a conserved sensorimotor structure that integrates visual and other sensory information to drive reflexive behaviors as mentioned in this paper, and the evidence for this is strong and compelling.About:

The tectum/superior colliculus as the vertebrate solution for spatial sensory integration and action
TL;DR: The superior colliculus is a part of the brain that registers events in the surrounding space, often through vision and hearing, but also through electrosensation, infrared detection, and other sensory modalities in diverse vertebrate lineages as mentioned in this paper.

TL;DR: In this article, an excitatory brain circuit from the superior colliculus (SC) to the substantia nigra pars compacta (SNc) was shown to enhance appetitive locomotion in mice.

High-density electrode recordings reveal strong and specific connections between retinal ganglion cells and midbrain neurons

TL;DR: In this paper , high-density electrodes simultaneously capture the activity of retinal axons and their postsynaptic target neurons in the superior colliculus, in vivo, and they show that retinal ganglion cell axons in the mouse provide a single cell precise representation of the retina as input to the superior cortex.

The Superior Colliculus: Cell Types, Connectivity, and Behavior
TL;DR: The superior colliculus (SC) is a well-characterized midbrain sensorimotor structure where visual, auditory, and somatosensory information are integrated to initiate motor commands, and cell-type specific SC neurons integrate afferent signals within local networks to generate defined output related to innate and cognitive behaviors as discussed by the authors .
Journal ArticleDOI
Cortical control of behavior and attention from an evolutionary perspective.
TL;DR: In this paper, the authors consider the evolution of cortical mechanisms for attention from the perspective of having to work through these subcortical bottlenecks, including preferential engagement of some cortical areas at the cost of disengagement from others to improve appropriate behavioral responses.

Shifts in selective visual attention: towards the underlying neural circuitry.
Christof Koch,Shimon Ullman +1 more
TL;DR: This study addresses the question of how simple networks of neuron-like elements can account for a variety of phenomena associated with this shift of selective visual attention and suggests a possible role for the extensive back-projection from the visual cortex to the LGN.

A saliency-based search mechanism for overt and covert shifts of visual attention.
Laurent Itti,Christof Koch +1 more
TL;DR: A detailed computer implementation of a saliency map scheme is described, focusing on the problem of combining information across modalities, here orientation, intensity and color information, in a purely stimulus-driven manner, which is applied to common psychophysical stimuli as well as to a very demanding visual search task.
Journal ArticleDOI
Saccade target selection and object recognition: evidence for a common attentional mechanism.
TL;DR: The spatial interaction of visual attention and saccadic eye movements was investigated in a dual-task paradigm that required a target-directed saccade in combination with a letter discrimination task and the results favor a model in which a single attentional mechanism selects objects for perceptual processing and recognition, and also provides the information necessary for motor action.
Journal ArticleDOI
Reorienting attention across the horizontal and vertical meridians: evidence in favor of a premotor theory of attention.
TL;DR: Neither the hypothesis postulating hemifield inhibition nor that postulating movement of attention with a constant time can explain the data, but the hypothesis of an attention gradient and that of attention movements with a constants speed are tenable in principle, but they fail to account for the effect of crossing the horizontal and vertical meridians.

Eye movements evoked by collicular stimulation in the alert monkey
TL;DR: Electrical stimulation of the superior colliculi of alert, behaving monkeys evoked allor-nothing saccades whose amplitude and direction were independent of stimulus parameters and depth within the colliculus and were thus not goal-directed.
