Integrated cortical field model of consciousness.
The idea that there is a localized module or limited capacity mechanism in the brain that subserves consciousness is wrong and this integrated cortical field model of consciousness is misconceived.
Exploring memory functions by means of brain electrical topography: A review
The main results are compatible with the idea that memory retrieval implies a reactivation of those cortical cell assemblies in the cortex in which the constituting features of a mnestic entity had originally been processed during perception and learning.
Convergence-Zone Episodic Memory: Analysis and Simulations
A Distributed Network for Multimodal Experiential Representation of Concepts
This work used representational similarity analysis of two large fMRI data sets to generate a detailed map of human brain regions where the semantic similarity structure across individual lexical concepts can be reliably detected and found that multimodal experiential information is encoded across a widely distributed network of cortical areas in both hemispheres.
Patterns of hippocampal–neocortical interactions in the retrieval of episodic autobiographical memories across the entire life‐span of aged adults
The role of a bilateral network of MTL and neocortical areas whose activation correlate during the recollection of rich phenomenological recent and remote EAMs is emphasized.
Neural populations in human posteromedial cortex display opposing responses during memory and numerical processing
Recording intracranially from the human posteromedial cortex provides important anatomical and temporal details—at the neural population level— of PMC engagement during autobiographical memory retrieval and addresses how the same populations are actively suppressed during tasks, such as numerical processing, which require externally directed attention.
Two functional components of the hippocampal memory system
It is proposed that neocortical association areas maintain shortterm memories for specific items and events prior to hippocampal processing as well as providing the final repositories of long-term memory.


Architecture and Connections of Cortical Association Areas
The execution of behavior depends on the integration of activity at various levels of the central nervous system. Nevertheless, different regions of the nervous system have been shown to participate
Posterior parietal association cortex of the monkey: command functions for operations within extrapersonal space.
A large proportion of area 5 neurons were relatively insensitive to passive joint rotations, as compared with similar neurons of the postcentral gyrus, but were driven to high rates of discharge when the same joint was rotated during an active movement of the animal.
Topography of cognition: parallel distributed networks in primate association cortex.
The structure and functions of the frontal lobes, particularly the prefrontal "silent" portion, have recently again become the subject of intense interest and the availability of solid new findings in experimental animals and human patients and the promise of further discoveries are undoubtedly the basis of this renewed interest.

It is suggested that in the brain the internal attentional searchlight, proposed by Treisman and others, is controlled by the reticular complex of the thalamus (including the closely related
Stimulus specific responses from beyond the classical receptive field: neurophysiological mechanisms for local-global comparisons in visual neurons.
The historical development of the evidence of response selectivity for visual stimuli presented beyond the CRF is traced; the anatomical pathways that sub serve these far-reaching surround mechanisms are examined; and the possible relationships between these mechanisms and perception are explored.
