BackgroundConsciousness poses two main problems. The first is understanding the conditions that determine to what extent a system has conscious experience. For instance, why is our consciousnessExpand
Consciousness as Integrated Information: a Provisional Manifesto

  • 1 December 2008
The integrated information theory (IIT) starts from phenomenology and makes use of thought experiments to claim that consciousness is integrated information. Specifically: (i) the quantity ofExpand
Sleep function and synaptic homeostasis.
This paper reviews a novel hypothesis about the functions of slow wave sleep-the synaptic homeostasis hypothesis. According to the hypothesis, plastic processes occurring during wakefulness result inExpand
The Sleep Slow Oscillation as a Traveling Wave
During much of sleep, virtually all cortical neurons undergo a slow oscillation (<1 Hz) in membrane potential, cycling from a hyperpolarized state of silence to a depolarized state of intense firing.Expand
From the Phenomenology to the Mechanisms of Consciousness: Integrated Information Theory 3.0
This paper presents Integrated Information Theory (IIT) of consciousness 3.0, which incorporates several advances over previous formulations. Expand
Breakdown of Cortical Effective Connectivity During Sleep
When we fall asleep, consciousness fades yet the brain remains active. Why is this so? To investigate whether changes in cortical information transmission play a role, we used transcranial magneticExpand
Sleep and the Price of Plasticity: From Synaptic and Cellular Homeostasis to Memory Consolidation and Integration
Sleep is universal, tightly regulated, and its loss impairs cognition. But why does the brain need to disconnect from the environment for hours every day? The synaptic homeostasis hypothesis (SHY)Expand
The Human Connectome: A Structural Description of the Human Brain
We propose a research strategy to achieve this goal, and discuss its potential impact in cognitive neuroscience and neuropsychology. Expand
Correlates of sleep and waking in Drosophila melanogaster.
Drosophila exhibits a circadian rest-activity cycle, but it is not known whether fly rest constitutes sleep or is mere inactivity. It is shown here that, like mammalian sleep, rest in Drosophila isExpand
Local sleep and learning
Human sleep is a global state whose functions remain unclear. During much of sleep, cortical neurons undergo slow oscillations in membrane potential, which appear in electroencephalograms as slowExpand
