Brain Network Connectivity in Anaesthesia and Disorders of Consciousness
Until recently, understanding the nature of consciousness was considered a philosophical pursuit. However, technological developments in brain imaging have allowed the study of consciousness as a natural, neurobiological phenomenon. The neurobiology of consciousness has been studied using cognitive …

Alpha thalamocortical networks during propofol general anesthesia and disorders of consciousness
Alpha (8-12 Hz) rhythms are a fundamental feature of awake electroencephalography (EEG), thought to be generated by circuits connecting the cortex and thalamus. These rhythms provide a functional architecture for cortical activity underpinning cognitive and sensory processing. Attenuation of alpha …

Standardisation and automatisation of the diagnosis of patients with disorders of consciousness: a machine learning approach applied to electrophysiological brain and body signals.
… in modern medicine have led to an increase of patients diagnosed with disorders of consciousness (DOC). In these conditions, patients are awake, but without behavioural signs of awareness. An accurate evaluation of DOC patients has medico-ethical and societal implications, and it is of …

Neural correlates of consciousness in the complexity of brain networks
How do we define consciousness? Besides philosophical endeavours, the development of modern neuroimaging techniques fostered a principled way of quantifying the neural correlates of consciousness. Acquiring and analysing resting-state functional magnetic resonance imaging (fMRI) and …

Complex, yet Resolved: Time-, Frequency-, and Information-resolved Approaches to Brain Function and Human Consciousness
Different perturbations of the brain’s delicate functioning, ranging from transient pharmacological interventions to severe trauma, can result in altered states of consciousness. To illuminate how the neurobiology and organization of the human brain support consciousness, we need to identify …

Functional Magnetic Resonance Imaging as an Assessment Tool in Critically Ill Patients
… cognitive function occurs in the earliest stages of brain injury. The overarching goal of the work presented in this dissertation was to elucidate the role of functional neuroimaging in assessing brain activity in critically ill patients. The overall objective was addressed in the following four …

Cognitive neuroscience framework of conscious dreaming: dream lucidity applications and novel induction protocols
Undertaken research consists of 9 peer-reviewed, publicly-accessible and published scientific articles. To contextualize the selected outputs as a coherent body of work, the aim and the body of this research portfolio can be demonstrated as a three-fold methodological approach. To investigate the …

Where Does it Stem From? - Functional Neuroimaging of Monoaminergic Brainstem Nuclei in Altered States of Consciousness: Translational, Diagnostic and Therapeutic Implications
Altered states of consciousness (ASCs) provide models through which the necessary and sufficient neural underpinnings for consciousness can be characterised. Indeed, the study of ASCs through human functional neuroimaging has identified large-scale cortical networks (such as the default mode …
