Neurophysiological and Computational Principles of Cortical Rhythms in Cognition
TL;DR: A plethora of studies will be reviewed on the involvement of long-distance neuronal coherence in cognitive functions such as multisensory integration, working memory, and selective attention, and implications of abnormal neural synchronization are discussed as they relate to mental disorders like schizophrenia and autism.
Journal ArticleDOI
Pathophysiology of Sleep Apnea
TL;DR: This work reviews three types of major long-term sequelae to severe OSA and discusses future research into understanding the pathophysiology of sleep apnea as a basis for uncovering newer forms of treatment of both the ventilatory disorder and its multiple sequelae.
Journal ArticleDOI
Cognitive and biological determinants of P300: an integrative review
John Polich,Albert Kok +1 more
TL;DR: The effects of natural and environmentally induced state variables on the P300 suggest that these factors contribute to P300 measures and are discussed in terms of their theoretical and applied implications.
Journal ArticleDOI
An information integration theory of consciousness
TL;DR: The information integration theory accounts, in a principled manner, for several neurobiological observations concerning consciousness, including the association of consciousness with certain neural systems rather than with others; the fact that neural processes underlying consciousness can influence or be influenced by neural processes that remain unconscious; the reduction of consciousness during dreamless sleep and generalized seizures.

SLEEP AND AROUSAL: Thalamocortical Mechanisms
David A. McCormick,Thierry Bal +1 more
TL;DR: The release of several different neurotransmitters from the brain stem, hypothalamus, basal forebrain, and cerebral cortex results in a depolarization of thalamocortical and thalamic reticular neurons and an enhanced excitability in many cortical pyramidal cells, thereby suppressing the generation of sleep rhythms and promoting a state that is conducive to sensory processing and cognition.

Tetramethyl benzidine for horseradish peroxidase neurohistochemistry: a non-carcinogenic blue reaction product with superior sensitivity for visualizing neural afferents and efferents.:
TL;DR: The sensitivity of this new method in demonstrating retrograde transport is markedly superior to that of the previously described benzidine dihydrochloride method and, as a consequence, many efferent connections of the injection site are also visualized.

Brain stem reticular formation and activation of the EEG
G. Moruzzi,Horace W. Magoun +1 more
TL;DR: In this paper, it was shown that reticular activation is associated with the activation of the reticular formation of the brain stem, and that reticulus activation can be induced by low frequency stimulation of the diffuse thalamic projection system, rather than intra-cortical spread following the arrival of afferent impulses at the sensory receiving areas of the cortex.

Magnesium gates glutamate-activated channels in mouse central neurones
TL;DR: The voltage dependence of the NMDA receptor-linked conductance appears to be a consequence of the voltage dependenceof the Mg2+ block and its interpretation does not require the implication of an intramembrane voltage-dependent ‘gate’.

Glycine potentiates the NMDA response in cultured mouse brain neurons
J. W. Johnson,P Ascher +1 more
TL;DR: G glycine may facilitate excitatory transmission in the brain through an allosteric activation of the NMDA receptor, and can be observed in outside-out patches as an increase in the frequency of opening of the channels activated by NMDA agonists.
