“…The two ventral visual field maps are strongly connected with occipital and temporal cortex in humans and other primate species (Gutierrez et al, 1995;Adams et al, 2000;Shipp, 2003). The connectivity of the anterior-most temporal area we investigated (PHC2) overlapped with these two maps but also extended into the posterior-most parts of the medial pulvinar, consistent with connectivity patterns of anterior ventral temporal cortex in other primate species (Benevento and Rezak, 1976;Baleydier and Morel, 1992;Baizer et al, 1993). Beyond these two maps, we identified coarse representations of contralateral space within the dorsal lateral and ventral medial pulvinar in humans.…”

“…Generally, cortical areas that are directly connected are also indirectly interconnected via the pulvinar with layerspecific cortical connections forming distinct feedforward and feedback loops. Individual visual areas project to specific parts of the pulvinar (Benevento and Rezak, 1976;However, the organization of these visual field maps appears to differ across primate species (Li et al, 2013). In humans, neuroimaging studies have demonstrated contralateral biases (Cotton and Smith, 2007) and some systematic representation of visual space within the ventral pulvinar (Schneider, 2011;DeSimone et al, 2015).…”

The pulvinar is the largest nucleus in the primate thalamus and contains extensive, reciprocal connections with visual cortex. Although the anatomical and functional organization of the pulvinar has been extensively studied in old and new world monkeys, little is known about the organization of the human pulvinar. Using high-resolution functional magnetic resonance imaging at 3 T, we identified two visual field maps within the ventral pulvinar, referred to as vPul1 and vPul2. Both maps contain an inversion of contralateral visual space with the upper visual field represented ventrally and the lower visual field represented dorsally. vPul1 and vPul2 border each other at the vertical meridian and share a representation of foveal space with iso-eccentricity lines extending across areal borders. Additional, coarse representations of contralateral visual space were identified within ventral medial and dorsal lateral portions of the pulvinar. Connectivity analyses on functional and diffusion imaging data revealed a strong distinction in thalamocortical connectivity between the dorsal and ventral pulvinar. The two maps in the ventral pulvinar were most strongly connected with early and extrastriate visual areas. Given the shared eccentricity representation and similarity in cortical connectivity, we propose that these two maps form a distinct visual field map cluster and perform related functions. The dorsal pulvinar was most strongly connected with parietal and frontal areas. The functional and anatomical organization observed within the human pulvinar was similar to the organization of the pulvinar in other primate species.

“…In the cat the X and Y systems constitute two parallel channels to the cortex, the X system terminating exclusively in area 17, and the Y system, in areas 17 and 18 [63]. Another difference is that in the cat the extrageniculate visual pathway is excluded from area 17 [61,64], whereas in the monkey area 17 receives afferences from tectorecipient areas of the pulvinar [65]. Hence, area 17 in the cat, reflecting exclusively geniculate input with a preponderance of the X system, would be more homogeneous than area 17 in the monkey.…”

Corollary discharge: Its possible implications in visual and oculomotor interactions

1979

Abstract--Data concerning the possible role of a corollary discharge mechanism in the regulation of visual-oculomotor interactions are reviewed. Several modes of action for such a mechanism on the processing of visual information are discussed. Mere suppression of visual input during saccades is considered mostly as a peripheral mechanism. It is proposed that corollary discharge could either produce an active cancellation of the effects of eye movements on vision, or contribute to the evaluation that a given visual change is provoked by a saccade. Cancellation could occur at subcortical levels of visual processing although evaluation could occur at the cortical level.

“…They tend to concentrate in the deep half of layer III and layers IVa, IV@, and Via of area 17, which receive input from the parvocellular layers of the lateral geniculate nuclei and are considered to be associated with the processing of color vision (Livingstone and Hubel, 1984;Jones, 1985;Lund and Yoshioka, 199 l), it is possible that (~2 receptors are also involved in this process. In addition, the ot2 receptors of areas 17 and 18 concentrate in the layers innervated by the pulvinar, such as layer I of area 17 and layers I, the deep half of III, and IV of area 18 (Benevento and Rezak, 1976;Lund, 1988). Such a close spatial correlation between the laminar distributions of pulvinar terminals and ot2 receptors suggests that these receptor sites may also participate in the modulation of the extrageniculate visual pathway (Jones, 1985).…”

“…For example, pulvinar terminals are found predominantly in layers I, III, IV, and VI at El00 (Kostovic and Rakic, 1984) while the 012 receptors begin to concentrate in the same layers only between El43 and birth. By that developmental age, the pulvinar innervation of area 18 had already changed to adult distribution, with axonal terminals concentrating in layers I, III, and IV (Benevento and Rezak, 1976). Similar distribution of ot2 receptors is achieved only by the end of the first postnatal year.…”

Unique profiles of the alpha 1-, alpha 2-, and beta-adrenergic receptors in the developing cortical plate and transient embryonic zones of the rhesus monkey

Film receptor autoradiography was used to study the distribution of alpha 1-, alpha 2-, and beta-adrenergic receptors in the occipital lobe of developing rhesus monkeys ranging in age from the 65th embryonic day (E65) to adulthood (5 years of age). The study shows that each adrenergic receptor subtype has a unique distribution in the cortical plate and transient embryonic zones of the developing cerebral wall. For example, alpha 1 receptors are prominent throughout the proliferative ventricular and subventricular zones while alpha 2 receptors in the same zones form three distinct bands interdigitated with three bands rich in beta sites. There are also considerable temporal differences in the emergence of adrenergic receptor subtypes in specific embryonic zones. For instance, the high density of alpha 1 sites in the germinal zones occurs only in conjunction with intensive proliferative activity. In contrast, beta receptors emerge in these zones after the majority of cortical neurons have been generated. The transient embryonic zones often display higher densities of adrenergic sites than the cortical plate itself. In particular, the subplate zone subjacent to the developing visual cortex contains the highest density of alpha 2-adrenergic sites in the cerebral wall throughout all prenatal ages studies. Finally, the regional differences in the density of beta-adrenergic receptors are evident in the subplate zone underlying the prospective striate and extrastriate cortex before such differences emerge in the cortical plate. The early appearance, unique pattern of distribution, and time-dependent changes of adrenergic receptors in the transient embryonic zones suggest their involvement in the regulation of the cortical development.
