“…To date, the evidence for this is somewhat supportive, but incomplete. In the inferior pulvinar, one systematic retinotopic map has been described in microelectrode mapping studies (the PI maps of Allman et al, 1972;Bender, 1981) and in studies of connection patterns with retinotopically organized areas of visual cortex (the PI/PL map of Ungerleider et al, 1983 or the P1 map of Ungerleider et al, 1984;Gattass et al, 1978;Gutierrez and Cusick, 1997). The results in these studies may largely reflect the organization of the largest subdivision of the inferior pulvinar, PICL (Adams et al, 2000).…”

The present study used injections of neuroanatomical tracers to determine the subcortical connections of the caudal and rostral subdivisions of the dorsolateral area (DL) and the middle temporal crescent area (MT(C)) in owl monkeys (Aotus trivirgatus), squirrel monkeys (Saimiri sciureus), and macaque monkeys (Macaca fascicularis and M. radiata). Emphasis was on connections with the pulvinar. Patterns of corticopulvinar connections were related to subdivisions of the inferior pulvinar (PI) defined by histochemical or immunocytochemical architecture. Connections of DL/MT(C) were with the PI subdivisions, PICM, PICL, and PIp; the lateral pulvinar (PL); and, more sparsely, the lateral portion of the medial pulvinar (PM). In squirrel monkeys, there was a tendency for caudal DL to have stronger connections with PICL than PICM and for rostral DL/MT(C) to have stronger connections with PICM than PICL. In all three primates, DL/MT(C) had reciprocal connections with the pulvinar and claustrum; received afferents from the locus coeruleus, dorsal raphe, nucleus annularis, central superior nucleus, pontine reticular formation, lateral geniculate nucleus, paracentral nucleus, central medial nucleus, lateral hypothalamus, basal nucleus of the amygdala, and basal nucleus of Meynert/substantia innominata; and sent efferents to the pons, superior colliculus, reticular nucleus, caudate, and putamen. Projections from DL/MT(C) to the nucleus of the optic tract were also observed in squirrel and owl monkeys. Similarities in the subcortical connections of the dorsolateral region, especially those with the pulvinar, provide further support for the conclusion that the DL regions are homologous in the three primate groups.

“…The pulvinar is a somewhat mysterious structure, both anatomically and functionally, and has been described as "+terra incognita of the thalamus" [33]. Recently, it has been established that the inferior pulvinar receives a retinotopic projection of the visual field, in the primate [4]. A parasagital section of the brain, showing a number of straight line electrode trajectories, along with the corresponding receptive field plots, is shown in Figure 4.…”

Spatial mapping in the primate sensory projection: Analytic structure and relevance to perception

1977

The retinotopic mapping of the visual field to the surface of the striate cortex is characterized as a logarithmic conformal mapping. This summarizes in a concise way the observed curve of cortical magnification, the linear scaling of receptive field size with eccentricity, and the mapping of global visual field landmarks. It is shown that if this global structure is reiterated at the local level, then the sequence regularity of the simple cells of area 17 may be accounted for as well. Recently published data on the secondary visual area, the medial visual area, and the inferior pulvinar of the owl monkey suggests that the same global logarithmic structure holds for these areas as well. The available data on the structure of the somatotopic mapping (area S-1) supports a similar analysis. The possible relevance of the analytical form of the cortical receptotopic maps to perception is examined and a brief discussion of the developmental implications of these findings is presented.

“…The retinotopic subcortical visual nucleithe superior colliculus (SC), the lateral geniculate nucleus (LGN), and two pulvinar nuclei-are highly spatial selective (Allman et al, 1972;Cynader and Berman, 1972;Goldberg and Wurtz, 1972;Malpeli and Baker, 1975;Bender, 1981;Benevento and Standage, 1983;Cusick et al, 1993;Schneider et al, 2004;Kastner, 2005, 2009), but their nonspatial feature selectivity varies: neurons in the superficial layers of the SC respond well to many stimuli largely independent of contrast, orientation, size, shape, or velocity (Humphrey, 1968;Schiller and Koerner, 1971;Cynader and Berman, 1972;Goldberg and Wurtz, 1972;Schiller and Stryker, 1972;Marrocco and Li, 1977); LGN neurons are segregated into layers of monochromatic and quickly adapting magnocellular neurons and chromatic and more sustained parvocellular neurons (Wiesel and Hubel, 1966;Dreher et al, 1976;Creutzfeldt et al, 1979;Shapley et al, 1981;Derrington and Lennie, 1984;Merigan and Maunsell, 1993;Schneider et al, 2004;Solomon et al, 2004); and pulvinar neurons encode features such as direction of motion and orientation (Mathers and Rapisardi, 1973;Gattass et al, 1979;Benevento and Miller, 1981;Bender, 1982;Petersen et al, 1985;Merabet et al, 1998;Casanova et al, 2001).…”

Subcortical Mechanisms of Feature-Based Attention

The degree to which spatial and feature-based attention are governed by similar control mechanisms is not clear. To explore this issue, I measured, during conditions of spatial or feature-based attention, activity in the human subcortical visual nuclei, which have precise retinotopic maps and are known to play important roles in the regulation of spatial attention but have limited selectivity of nonspatial features. Subjects attended to and detected changes in separate fields of moving or colored dots. When the fields were disjoint, spatially attending to one field enhanced hemodynamic responses in the superior colliculus (SC), lateral geniculate nucleus (LGN), and two retinotopic pulvinar nuclei. When the two dot fields were spatially overlapping, feature-based attention to the moving versus colored dots enhanced responses in the pulvinar nuclei and the majority of the LGN, including the magnocellular layers, and suppressed activity in some areas within the parvocellular layers; the SC was inconsistently modulated among subjects. The results demonstrate that featurebased attention operates throughout the visual system by prioritizing neurons encoding the attended information, including broadly tuned thalamic neurons. I conclude that spatial and feature-based attention operate via a common principle, but that spatial location is a special feature in that it is widely encoded in the brain, is used for overt orienting, and uses a specialized structure, the SC.
