“…Previous studies have shown that the SMI-32 antibody labels preferentially cells related to the magnocellular pathway, at both thalamic and cortical levels (Campbell and Morrison, 1989;Hof and Morrison, 1995;Chaudhuri et al, 1996;Hof et al, 1996;Bourne and Rosa, 2003;Baldauf, 2005;Van der Gucht et al, 2005). In this study we showed that in the LGN of Cebus monkey, staining with SMI-32 labeled the magnocellular layer more intensely than the parvocellular ones, similar to what has been described in vervet monkey (Chaudhuri et al, 1996) and in marmoset (Bourne and Rosa, 2003).…”

“…A differential distribution of SMI-32-ir neurons was also observed across cortical areas (Campbell and Morrison, 1989;Hof and Morrison, 1995;Chaudhuri et al, 1996;Bourne and Rosa, 2003;Baldauf, 2005;Van der Gucht et al, 2005, 2006. In macaque monkey, visual areas related to the magnocellular system in the superior temporal sulcus (STS) and parietal cortices are all characterized by the presence of very large SMI-32-ir neurons in layer 5A.…”

We investigated the distribution pattern of SMI-32-immunopositive cells in the lateral geniculate nucleus (LGN) and in the primary (V1) and middle temporal (MT) cortical visual areas of the adult New World monkey Cebus apella. In the LGN, the reaction for SMI-32 labeled cells in both the magnocellular (M) and parvocellular (P) layers. However, the cellular label was heavier in M layers, which also showed a more intense labeling in the neuropil. In V1, the reaction showed a lamination pattern, with the heaviest labeling occurring in layer 4B and upper layer 6 (layers that project to area MT). Area MT shows a dense band of labeled neuropil and large pyramidal neurons in layer 3, large darkly labeled but less densely packed neurons in layer 5, and a population of small, lightly labeled cells in layer 6. These results resemble those found in other New and Old World monkeys, which suggest that the preferential labeling of projection neurons associated with fast-conducting pathways to the extrastriate dorsal stream is a common characteristic of simian primates. In the superficial layers of V1 in Cebus monkeys, however, SMI-32-labeled neurons are found in both cytochrome oxidase blobs and interblob regions. In this aspect, our results in Cebus are similar to those found in the Old World monkey Macaca and different from those described for squirrel monkey, a smaller New World Monkey. In Cebus, as well as in Macaca, there is no correlation between SMI-32 distribution and the blob pattern.

“…In the dorsal lateral geniculate nucleus (LGN) of primates, a stronger expression of N‐NF protein was observed in the magnocellular layers, compared with the parvocellular layers (Chaudhuri et al,1996; Bourne and Rosa,2003).

Polyurethane (PU) composites incorporating Cloisite 15A (15A) were prepared via melt compounding and solvent casting. The melt‐compounded composites had better dispersion and a smaller silicate stack size as a result of the higher shear forces associated with twin‐screw extrusion. The PU microphase separation and hard domain order were greater in the melt‐processed materials. At the concentrations of 15A employed in this study (≤7 wt %), the filler did not have an observable effect on the microphase texture of either the solvent‐ or melt‐processed PU. The tensile properties of the melt‐compounded materials were lower than those of their solvent‐cast counterparts because of thermal degradation. The solvent‐cast composite containing a 3 wt % loading of 15A displayed improved tensile strength and elongation, primarily because of plasticization by the silicate organic treatment. The addition of layered silicates with high aspect ratios increased the hysteresis and permanent set of this PU elastomer. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 97: 300–309, 2005

“…The circuit contains both glutamatergic and GABAergic neurons, as shown by costaining for transduced cells and neuron type-specific markers [13]. Correlatively, activity-dependent gene imaging detects activity in both glutamatergic and GABAergic neurons; in particular, following light or sensory stimulation, activity-dependent gene imaging visualizes activity in both neuron types in cat primary visual cortex [34–39]. Correlatively, physiological activation of circuits activates both neuron types.…”

Synaptic plasticity and neural network theories hypothesize that the essential information for advanced cognitive tasks is encoded in specific circuits and neurons within distributed neocortical networks. However, these circuits are incompletely characterized, and we do not know if a specific discrimination is encoded in characteristic circuits among multiple animals. Here, we determined the spatial distribution of active neurons for a circuit that encodes some of the essential information for a cognitive task. We genetically activated protein kinase C pathways in several hundred spatially-grouped glutamatergic and GABAergic neurons in rat postrhinal cortex, a multimodal associative area that is part of a distributed circuit that encodes visual object discriminations. We previously established that this intervention enhances accuracy for specific discriminations. Moreover, the genetically-modified, local circuit in POR cortex encodes some of the essential information, and this local circuit is preferentially activated during performance, as shown by activity-dependent gene imaging. Here, we mapped the positions of the active neurons, which revealed that two image sets are encoded in characteristic and different circuits. While characteristic circuits are known to process sensory information, in sensory areas, this is the first demonstration that characteristic circuits encode specific discriminations, in a multimodal associative area. Further, the circuits encoding the two image sets are intermingled, and likely overlapping, enabling efficient encoding. Consistent with reconsolidation theories, intermingled and overlapping encoding could facilitate formation of associations between related discriminations, including visually similar discriminations or discriminations learned at the same time or place.
