TL;DR
It is suggested that the connections between these cortical areas of the macaque monkey visual system never form strong, directed loops, and it is predicted that certain types of connections will not be found.
Abstract
The many distinct cortical areas of the macaque monkey visual system can be arranged hierarchically, but not in a unique way. We suggest that the connections between these cortical areas never form strong, directed loops. For connections between the visual cortex and particular thalamic nuclei, we predict that certain types of connections will not be found. If strong, directed loops were to exist, we suggest that the cortex would go into uncontrolled oscillations.

Results suggest that the best stimulus for exciting a cell (that is, a neural code) is coincident bursts, which provide more-precise information than action potentials that arrive singly.

NatureAre we aware of neural activity in primary visual cortex?

The neuroanatomy of the macaque monkey suggests that, although primates may be aware of neural activity in other visual cortical areas, they are not directly aware of that in area V1 of the neocortex.
Journal of NeurophysiologyFunctional organization of thalamocortical relays
767 Citations1996S. Murray Sherman, R. W. Guillery
Although the specific function of the circuits and cellular properties of the thalamic relay for waking behavior is far from clear, two related hypotheses are offered based on recent experimental evidence: one is that theThalamus is not used just to relay peripheral information from, for example, visual, auditory, or cerebellar inputs, but that someThalamic nuclei are arranged instead to relay information from one cortical area to another.

617 Citations1998Edward M. Callaway
The basic laminar organization of excitatory local circuitry in the primary visual cortex of the macaque monkey is similar to that described previously in the cat's visual cortex, but within this basic framework is a more complex organization.

The activation dynamics of nets are considered from a rigorous mathematical point of view and an extension of the Cohen-Grossberg convergence theorem is proved for certain nets with nonsymmetric weight matrices.

Inferior temporal areas TEO and TE were injected with WGA-HRP and 3H-AA, respectively, or vice versa, in 1-week-old infant and 3-4-year-old adult monkeys (Macaca mulatta), the results indicated that whereas TEO has more extensive connections with parietal areas, TE has more comprehensive connections with prefrontal areas.
NatureFeature-linked synchronization of thalamic relay cell firing induced by feedback from the visual cortex
563 Citations1994Adam M. Sillito, Helen Jones +2 more
It is reported that when driven by moving oriented visual stimuli the cortical feedback induces correlated firing in relay cells, and proposed that this feedback loop serves to lock or focus the appropriate circuitry onto the stimulus feature.

370 Citations1995R. W. Guillery
It is proposed that the higher-order nuclei are largely concerned with transmitting information about the output of one cortical area to another cortical area, and that they are likely to play a key role in corticocortical communication and higher cortical functions.

It is demonstrated that corticothalamic fibers arising from the rat primary visual cortex display a lamina-dependent projection pattern and it is proposed that a similar organizational plan characterizes cortic hypothalamic relationships in other sensory systems in the rat and in other species.

Upper layers of the cat primary visual cortex can be directly driven by inputs from secondary visual cortex when activity in middle layers is disrupted and may be able to extract considerable information from higher order areas.

Interestingly, the geniculocortical input to cortex has been largely neglected in favor of analyses of intracortical circuitry, but in view of the basic importance of this afferent input, it is suggested that more quantitative data about it should be generated, so that a better assessment can be made of its extent.

133 Citations1996Kathleen S. Rockland
Indirect evidence, presented here, suggests that the more numerous medium‐sized neuronsGive rise to E axons, and the sparser giant pyramids give rise to R corticopulvinar axons; if this is correct, corticospecific connectivity may be involved in multiple transformations.

The inferior pulvinar (PI) was identified as a neurochemically distinct region that included the traditional cytoarchitectonic nucleus PI and adjacent portions of the lateral and medial pulvmar nuclei, PL and PM and was distinguished by less intense staining for calbindin and many cells stained with the SMI‐32 antibody for neurofilament protein.

103 Citations1972Lawrence H. Mathers
Electron microscopic examination shows that parts of two different populations of synaptic terminals degenerate as a result of the cortical lesions: the RS terminal which rapidly becomes electron‐dense and later is phagocytosed, and the RL terminal, which initially exhibits signs of neurofilamentous hyperplasia and later becomes electron-dense.

The results show that the increased CO staining in certain subregions of V2 is closely correlated with the presence of thalamic terminals from the pulvinar, which suggests another potential source of integration between the two cortical visual streams.
