Coupling the State and Contents of Consciousness
- BiologyFront. Syst. Neurosci.
The present perspective suggests that L5p neurons have a central role in the mechanisms underlying consciousness, and makes one quite specific prediction: cortical processing that does not include L5P neurons will be unconscious.

Dendritic integration theory: A thalamo-cortical theory of state and content of consciousness
- BiologyPhilosophy and the Mind Sciences
This view bridges two long-standing perspectives on the neural mechanisms of consciousness and proposes that cortical and thalamo-cortical processing interact at the level of single pyramidal cells.
Consciousness, anesthesia, and the thalamocortical system.
The vault of the thalamus is unlocked by using magnetic resonance imaging to differentiate the role of specific and nonspecific thalamocortical systems in propofol-induced unconsciousness.
Representational ‘touch’ and modulatory ‘retouch’—two necessary neurobiological processes in thalamocortical interaction for conscious experience
- Psychology, BiologyNeuroscience of consciousness
In the perceptual retouch theory of thalamocortical interaction, recently developed to become a blend with the dendritic integration theory, consciousness states and contents of consciousness are explained by the same mechanism.
CONSCIOUSNESS DISORDERS AS THE POSSIBLE EFFECT OF BRAINSTEM ACTIVITY FAILURE - COMPUTATIONAL APPROACH
Human consciousness is perceived ability to be aware of himself and environment. Control of human consciousness, as a result of information integration, seems be one of the most complex processes…

Interactions between phasic alerting and consciousness in the fronto-striatal network
- Biology, PsychologyScientific reports
Investigation of the neural mechanisms associated with endogenous spatial attention and phasic alertness and their interaction with the conscious perception of near-threshold stimuli suggest that not all attentional systems are equally effective in enhancing conscious perception, highlighting the importance of thalamo-cortical circuits on the interactions between alerting and consciousness.
Changes in the thalamocortical connectivity during anesthesia-induced transitions in consciousness
- Biology, PsychologyNeuroreport
Effective connectivity between the cortex and the ventral lateral thalamus was altered such that the primary motor and the primary somatosensory cortex Granger-caused the ventrobasal thalamic nuclei before loss of consciousness and after loss of Consciousness.

Neural correlates of consciousness in humans
- Biology, PsychologyNature Reviews Neuroscience
Functional neuroimaging in humans and electrophysiology in awake mokeys indicate that there are important differences between striate and extrastriate visual cortex in how well neural activity correlates with consciousness.
Intrathalamic sensory connections mediated by the thalamic reticular nucleus
- BiologyCellular and Molecular Life Sciences CMLS
It is proposed that, during wakefulness, TRN is crucially involved in resetting the activity levels in sensory nuclei of the dorsal thalamus, which allows the cortex to actively and periodically compare its on-going sensory processing with the available sensory information.
A thalamic reticular networking model of consciousness
- BiologyTheoretical Biology and Medical Modelling
The TRN-modulation hypothesis for conscious awareness is proposed, which provides a comprehensive rationale regarding previously reported psychological phenomena and neurological symptoms such as blindsight, neglect, the priming effect, the threshold/duration problem, and TRn-impairment resembling coma.
The neuronal basis for consciousness.
- BiologyPhilosophical transactions of the Royal Society of London. Series B, Biological sciences
The goal of this paper is to explore the basic assumption that large-scale, temporal coincidence of specific and non-specific thalamic activity generates the functional states that characterize human cognition.

This volume studies consciousness as a function, reviewing different levels and states of consciousness across the sleep-waking cycle; thalamocorticol coherence and consciousness; language contrivance on consciousness; and contributions of human brain mapping.
Reciprocal inhibitory connections and network synchrony in the mammalian thalamus.
Neuronal rhythmic activities within thalamocortical circuits range from partially synchronous oscillations during normal sleep to hypersynchrony associated with absence epilepsy. It has been proposed…
Function of the thalamic reticular complex: the searchlight hypothesis.

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…

It is suggested that the quickest route to a better understanding of C involves more intensive study of ILN, because no other structure seems, in the light of current knowledge, a more likely site for Mc.
