pulvinar

 [pul-vi´nar]
the prominent, cushionlike mass of nuclei that forms the medial portion of the posterior extremity of the thalamus, which partly overhangs the rostral colliculus and its brachium and is separated inferiorly from the geniculate body by the brachium of the rostral colliculus; it receives fibers from other thalamic nuclei and gives off widespread cortical projections.

pul·vi·nar

(pŭl-vī'năr),
The expanded caudal extremity of the thalamus that forms a cushionlike prominence overlying the geniculate bodies. This structure, collectively called nuclei pulvinares [TA] (pulvinar nuclei [TA]), is a composite cell group made up of anterior, inferior, lateral, and medial nuclei.

pulvinar 

The prominence of the posterior portion of the thalamus overlapping the superior colliculus. It receives projections from the auditory, somatosensory and visual cortex regions. It is involved in visual attention, suppression of irrelevant stimuli and utilizing information to initiate eye movements.

The emotional modulation of the orienting by conflict interaction in high anxious participants suggests that these individuals might have had difficulties to adjust their attentional focus to localize the target, an operation that previous studies have attributed to the pulvinar nucleus of the thalamus (LaBerge & Buchsbaum, 1990).
