By using immunohistochemical methods, we examined the distribution of cells expressing subunits of α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionate (AMPA)‐selective glutamate receptors (GluR2/3) in the cortical areas of the occipitotemporal pathway in monkeys. GluR2/3‐immunoreactive (‐ir) cells were primarily pyramidal cells; this category, however, also included large stellate cells in layer IVB of the striate cortex (V1) and fusiform cells in layer VI of all the areas examined. GluR2/3… 
Ionotropic glutamate receptors: Which ones, when, and where in the mammalian neocortex
The published expression of iGluR subunits in the areas and cell types of developing and adult cortex of rat, mouse, carnivore, bovine, monkey, and human as determined with antibody‐ and mRNA‐based techniques is compiled.
Expression of transcripts encoding AMPA receptor subunits and associated postsynaptic proteins in the macaque brain
The results suggest that AMPA subunits and related intracellular proteins are differentially distributed in the macaque brain, and in numerous structures there are significant mismatches, suggesting additional functional properties of the associated intrACEllular proteins.
Differential Expression Patterns of occ1-Related Genes in Adult Monkey Visual Cortex
The results resonate with previous works on chemical and functional gradients along the primate occipitotemporal visual pathway and raise the possibility that these gradients and functional architecture may be related to the visual activity–dependent expression of these extracellular matrix glycoproteins.
Topographic and laminar maturation of striate cortex in early postnatal marmoset monkeys, as revealed by neurofilament immunohistochemistry.
An inside-out profile of postnatal cortical development is demonstrated, with the topographic pattern of maturation of V1 mimicking the centroperipheral gradient of m maturity in the retina.
Dopamine Receptor Expression Among Local and Visual Cortex-Projecting Frontal Eye Field Neurons.
It is demonstrated that dopamine tends to act directly on the output of the FEF and that dopaminergic modulation of top-down projections to visual cortex is achieved predominately via D1Rs.
Selective gene expression in regions of primate neocortex: Implications for cortical specialization
Resolving the organization of the New World monkey third visual complex: The dorsal extrastriate cortex of the marmoset (Callithrix jacchus)
The present results argue in favor of the hypothesis that the third visual complex in New World monkeys contains different areas in its dorsal and ventral components: area DM, near the dorsal midline, and a homolog of area 19 of other mammals, located more lateral and ventrally.
Connections between the anterior inferotemporal cortex (area TE) and CA1 of the hippocampus in monkey
In this report, injections of tracer substances demonstrate that part of the dorsal subdivision of TE sends projections to CA1, but does not receive reciprocating projections back, which contrasts with the bi-directional connections between the more ventral subdivision, TEav, and CA1.
Long-Term Memory Search across the Visual Brain
The author explores how amygdala projections to the visual cortex affect the memory formation and proposes the choice of experimental techniques needed to explain the authors' massive visual memory capacity.


Non‐NMDA glutamate receptors are present throughout the primate hypothalamus
The localization of non‐N‐methyl‐D‐aspartate glutamate receptor subunits to neurons throughout the macaque hypothalamus provides further evidence for the glutamatergic regulation of neuroendocrine, autonomic, and limbic circuits.
Localization of AMPA-selective glutamate receptor subunits in the adult cat visual cortex.
The results described here provide a reference for future studies dealing with the effect of visual deprivation on the expression of this receptor type and indicate a high expression of GluR1-3 subunits in the cat visual cortex.
Cellular localizations of AMPA glutamate receptors within the basal forebrain magnocellular complex of rat and monkey
The cellular localizations of the AMPA subtype of GluR are different within the BFMC of rat and monkey, suggesting that excitatory synaptic regulation of distinct subsets of BFMC neurons may differ among species.
Quantitative localization of AMPA/kainate and kainate glutamate receptor subunit immunoreactivity in neurochemically identified subpopulations of neurons in the prefrontal cortex of the macaque monkey
There is a high degree of specificity in the distribution of AMPA/kainate and kainate receptor-class proteins to subclasses of neurons within the neocortex, which defines the role of identified sub classes of neurons in the complex circuitry of the cerebral cortex.
Immunocytochemical Characterization of AMPA-Selective Glutamate Receptor Subunits: Laminar and Compartmental Distribution in Macaque Striate Cortex
These findings demonstrate that AMPA subunit immunoreactivity is densely concentrated in layers and compartments receiving direct geniculocortical innervation.
Distribution and patterns of connectivity of interneurons containing calbindin, calretinin, and parvalbumin in visual areas of the occipital and temporal lobes of the macaque monkey
Immunocytochemical techniques were used to examine the distribution of double‐bouquet cells and chandelier cells that were immunoreactive (‐ir) for the calcium‐binding proteins calbindin (CB),
The human temporal cortex: characterization of neurons expressing nitric oxide synthase, neuropeptides and calcium-binding proteins, and their glutamate receptor subunit profiles.
Results show that specific subpopulations of neurochemically identified nonpyramidal cells may be activated via different receptor subtypes, and facilitation of subsets of these cells via differentceptor subunits may activate different inhibitory circuits.
