This study delves into an examination of heart rhythm patterns among patients afflicted with disorders of consciousness. The research primarily focuses on the analysis of polysomnographic recordings in the time domain while also exploring methodologies for evaluating peripheral signals. An algorithm aimed at detecting…

Deep anaesthetisation is an important surgical and explorative tool in the study of consciousness. Much work has been done to connect the deeply anaesthetised condition with decreased functional complexity. However, anaesthesia-induced unconsciousness is also a dynamic condition in which functional activity and…

Recently, the self has become an important focus of conscious mind research. Neuroimaging studies reveal that the self emerges from the spontaneous activity of cortical midline structures (CMS). Prefrontal cortex structures are also mentioned prominently in consciousness theories such as higher-order and global…

The default mode network`s (DMN) can be investigated using default EEG reactivity (DER).The default oscillatory macrostate (DEM) is exemplified by the macrostate showing thehighest decrease in occurrence probability during intermittent photic stimulation (IPS).This study aimed to investigate DER, in the deeply sedated…

Anesthesia is ubiquitous in hospitals, yet a mechanistic understanding of how anesthetic drugs induce unconsciousness is lacking. A prominent hypothesis suggests that dynamic stability is critical to cortical function: awake brains are poised at a state that is sufficiently excitable for activity generation and…

The role of the interface between internal and external factors which shape an agent's experience have been considered for millennia. In the 21st century, we have access to new technologies and ideas, but what are the breakthroughs we need that will afford new discoveries? Similarly, what disciplinary boundaries are…

Objective and quantitative assessment of the level of consciousness is a medical demand in clinics and a theoretical challenge to be addressed. Although a growing body of literature suggests different measures to distinguish the levels of consciousness, a systematic comparison of different measures is lacking. Such a…

What are the parallels between Intuitionistic Mathematics and Neurophenomenology, and their implications for how we conceptualize Computation? Inspired by AA Cavia’s recently published ‘Logiciel’ and work with the OREL Cognition Futures Reading Group, I hope to connect these foundational innovations in Mathematics and…

Learning a word, involves mapping low-level perceptual representations of world-referents to high-level semantic representations. It is widely held that conscious access to the visual world-referents is needed to learn the meaning of words. The aim of this study was to use fMRI-based decoded neurofeedback (DecNef) to…

The global workspace theory (GWT), proposed by Bernard Baars in 1988, claims that consciousness results from extensive and highly integrated cortico-thalamic activity. According to the hypothesis, conscious cognitive content is globally available in the brain for a variety of cognitive functions such as attention,…

Understanding the circuit mechanisms underlying the loss of consciousness during general anesthesia is a long-standing question. Activity within cortex drives conscious perception and, hence, the loss of consciousness is thought to result from the disconnection of cortex from subcortex. Here, we identify a change in…
