TLDR
This work discusses neuronal-network and regional forebrain activity during sleep, and its consequences for consciousness and cognition, and indicates possible roles for sleep in neuroplasticity.Abstract:
Sleep can be addressed across the entire hierarchy of biological organization. We discuss neuronal-network and regional forebrain activity during sleep, and its consequences for consciousness and cognition. Complex interactions in thalamocortical circuits maintain the electroencephalographic oscillations of non-rapid eye movement (NREM) sleep. Functional neuroimaging affords views of the human brain in both NREM and REM sleep, and has informed new concepts of the neural basis of dreaming during REM sleep — a state that is characterized by illogic, hallucinosis and emotionality compared with waking. Replay of waking neuronal activity during sleep in the rodent hippocampus and in functional images of human brains indicates possible roles for sleep in neuroplasticity. Different forms and stages of learning and memory might benefit from different stages of sleep and be subserved by different forebrain regions.read more

About sleep's role in memory
Bjoern Rasch,Jan Born,Jan Born +2 more
TL;DR: This review aims to comprehensively cover the field of "sleep and memory" research by providing a historical perspective on concepts and a discussion of more recent key findings.

The brain basis of emotion: A meta-analytic review
TL;DR: A meta-analytic summary of the neuroimaging literature on human emotion finds little evidence that discrete emotion categories can be consistently and specifically localized to distinct brain regions, and finds evidence that is consistent with a psychological constructionist approach to the mind.

Nonlinear dynamical analysis of EEG and MEG: Review of an emerging field
TL;DR: Interpretation of results in terms of 'functional sources' and 'functional networks' allows the identification of three basic patterns of brain dynamics: normal, ongoing dynamics during a no-task, resting state in healthy subjects, and hypersynchronous, highly nonlinear dynamics of epileptic seizures and degenerative encephalopathies.
Journal ArticleDOI
Grouping of brain rhythms in corticothalamic systems
TL;DR: The experimental evidence for unified oscillations derived from simultaneous intracellular recordings of cortical and thalamic neurons in vivo, while recent studies in humans using global methods provided congruent results of grouping different types of slow and fast oscillatory activities.

The distributed human neural system for face perception.
TL;DR: A model for the organization of this system that emphasizes a distinction between the representation of invariant and changeable aspects of faces is proposed and is hierarchical insofar as it is divided into a core system and an extended system.

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.
The Emotional Brain
TL;DR: In The Emotional Brain, Joseph LeDoux investigates the origins of human emotions and explains that many exist as part of complex neural systems that evolved to enable us to survive.
