Cognitive theories on consciousness propose a strong link between consciousness and working memory (WM). This link is also present at the neural level: Both consciousness and WM have been implicated in a prefrontal parietal network. However, the link remains empirically unexplored. The present study investigates the relation between consciousness and WM by studying the impact of WM load on one ...
Understanding the nature of consciousness has been an outstanding scientific puzzle at the crossroads of neuroscience and artificial intelligence. While brains have long since known to be the bearers of consciousness and machines, that of computation, the history of cybernetics has been full of attempts trying to synthesize consciousness in computational architectures. In recent years, ideas fr...
Alterations in consciousness are central to epileptic manifestations, and involve changes in both the level of awareness and subjective content of consciousness. Generalised seizures are characterised by minimal responsiveness and subjective experience whereas simple and complex partial seizures demonstrate more selective disturbances. Despite variations in ictal origin, behaviour and electroph...
OBJECTIVE We aimed to investigate the roles of different resting-state networks in predicting both the actual level of consciousness and its recovery in brain injury patients. METHODS We investigated resting-state functional connectivity within different networks in patients with varying levels of consciousness: unresponsive wakefulness syndrome (UWS; n = 56), minimally conscious state (MCS; ...
The book “The origin of consciousness in the breakdown of the bicameral mind” of Julian Jaynes provides, not only a fascinating scenario about the evolution of modern consciousness from the consciousness of bicameral stone age man, but also a holistic view about schizophrenic consciousness. In fact, Jaynes regards schizophrenic as a bicameral man receiving commands of “God” as auditory and visu...
The intrinsic connectivity of the default mode network has been associated with the level of consciousness in patients with severe brain injury. Especially medial parietal regions are considered to be highly involved in impaired consciousness. To better understand what aspect of this intrinsic architecture is linked to consciousness, we applied spectral dynamic causal modeling to assess effecti...
