SummaryIn order to investigate whether pulvinar lesions produce behavioral impairments similar to those that follow superior colliculus lesions, monkeys were tested on a visual search task before and after receiving radiofrequency lesions of either the superior colliculus or pulvinar. The animals searched for a small target pattern within an array of varying numbers of irrelevant patterns. After receiving colliculus lesions, the animals showed marked postoperative increases in either search… Expand
Saccadic eye movements following kainic acid lesions of the pulvinar in monkeys
TLDR
It is suggested that the neglect, increased saccadic latencies, and prolonged fixations attributed to pulvinar damage in previous studies were probably the result instead of inadvertent damage to tectal afferents. Expand
Pulvinar-cortical interactions for spatial perception and goal-directed actions in non-human primates
TLDR
The pulvinar plays a functional role in the brain network dedicated to visual attention and visuomotor processing with its effective connectivity strongly overlapping with the connectivity pattern found for the lateral intraparietal area (LIP), a node of the same brain network but located in posterior parietal cortex. Expand
The role of the human pulvinar in visual attention and action: evidence from temporal-order judgment, saccade decision, and antisaccade tasks.
TLDR
The demonstration that pulvinar damage affects both attention and oculomotor behaviour highlights the role of this structure in the integration of visual and oulomotor signals and, more generally, its role in flexibly linking visual stimuli with context-specific motor responses. Expand
Pulvinar Inactivation Disrupts Selection of Movement Plans
TLDR
It is found that unilateral pulvinar inactivation resulted in a spatial neglect syndrome accompanied by visuomotor deficits including optic ataxia during visually guided limb movements, highlighting the importance of the dorsal aspect of the Pulvinar nucleus as a critical hub for spatial attention and selection of visually guided actions. Expand
Electrical Microstimulation of the Pulvinar Biases Saccade Choices and Reaction Times in a Time-Dependent Manner
TLDR
Results show that the dPul plays a primary role in action planning as opposed to visual processing, that it exerts its strongest influence on spatial choices when decision and action are temporally close, and that this choice effect can be dissociated from motor effects on saccade initiation and execution. Expand
Neural activity in the visual thalamus reflects perceptual suppression
TLDR
It is demonstrated that visual responses of pulvinar neurons reflect the perceptual awareness of a stimulus, while those of LGN neurons do not, and these responses are sorted on the basis of the trial-to-trial visibility of the stimulus. Expand
Pulvinar-Cortex Interactions in Vision and Attention
TLDR
Cortex interactions with the ventro-lateral pulvinar are necessary for normal attention and sensory processing and for maintaining the cortex in an active state and caused an increase in low-frequency cortical oscillations. Expand
Gating and control of primary visual cortex by pulvinar
TLDR
Lateral pulvinar is able to powerfully control and gate information outflow from V1, and its effect on supra-granular layers of V1 that project to higher visual cortex is assessed. Expand
Effective connectivity and spatial selectivity-dependent fMRI changes elicited by microstimulation of pulvinar and LIP
TLDR
Spatial task-specific and partly polysynaptic modulations of cue and saccade planning delay period activity in both hemispheres exerted by unilateral pulvinar and parietal stimulation provide insight into the distributed interhemispheric processing underlying spatial behavior. Expand
The Role of Pulvinar in the Transmission of Information in the Visual Hierarchy
TLDR
To investigate representation of stimulus contrast a hierarchical model network of ten cortical areas is examined, and the cortico-pulvino-cortical output presents much more sensitivity to contrast and has a similar level of contrast invariance of the tuning. Expand

Effect of pulvinar lesions on visual pattern discrimination in monkeys.
TLDR
The attentional aspects of the visual pattern-discrimination task employed in this study and the additional effects obtained with distracting stimuli suggest that the impairments arising from inferior pulvinar lesions may be dependent in part on visual attentional factors. Expand
Localization and detection of visual stimuli in monkeys with pulvinar lesions
TLDR
It is concluded that the pulvinar is not critical for the ability to locate and detect brief visual stimuli, but rather to interruption of corticotectal fibers that pass through the Pulvinar. Expand

TLDR
It is suggested that superior colliculus and striate cortex may be involved in two different aspects of attention: respectively, shifting attention (and orientation) from one spatial locus to another and maintaining attention on fixated stimuli. Expand
Size constancy in rhesus monkeys: Effects of pulvinar, prestriate, and inferotemporal lesions
TLDR
All monkeys reacquired the discrimination postoperatively, indicating that there are multiple mechanisms available to the brain-damaged animal for the perception of size constancy. Expand
Localization and detection of visual stimuli following superior colliculus lesions in rhesus monkeys
TLDR
Rhesus monkeys showed persistent deficits in localizing flashes presented 43-80 degrees from the fixation stimulus, but they were not consistently impaired when the flashes were presented more centrally, and their performance with peripheral stimuli improved when the stimulus duration was 1 sec.

Inferotemporal versus combined pulvinar-prestriate lesions in the rhesus monkey: Effects on color, object and pattern discrimination
TLDR
Qualitatively different effects of inferotemporal and combined pulvinar-prestriate lesions are discussed in terms of current models of central processing of visual information. Expand
The effects of pretectal and superior collicular lesions on binocular vision
TLDR
It is proposed that an abnormality of vergence eye movements provides a simple explanation for some of the so-called perceptual impairments that follow damage to the mid-brain visual pathways in monkeys. Expand

TLDR
Analysis of the latencies of individual trials suggest that scanpaths over the display were still systematic after the lesions, suggesting that the search was being slowed down either by the need to make more correction saccades to give accurate fixations of the stimuli being discriminated, or by an increase in latencies specificially for those saccade that shift the gaze between stimuli. Expand
Further analysis S-R separation effects on visual discrimination performance of normal rhesus monkeys and monkeys with superior colliculus lesions.
TLDR
Rhesus monkeys discriminated between two color-differentiated stimuli presented on a screen only when they fixated the center of the screen, suggesting that the stimulus-response separation effect is due to selective attention to the response sites and not to fixating them during stimulus presentation. Expand
Effects of kainic acid and radiofrequency lesions of the pulvinar on visual discrimination in the monkey
TLDR
The findings suggest that corticotectal projections traversing the pulvinar and destroyed by the thermocoagulation lesions are crucial to the performance of discriminations involving S-R separation and may be crucial for the contribution of the colliculus to performance in a variety of visual tasks.
