Nonrapid eye movement (NREM) sleep is associated with fading consciousness in humans. Recent neuroimaging studies have demonstrated the spatiotemporal alterations of the brain functional connectivity (FC) in NREM sleep, suggesting the changes of information integration in the sleeping brain. However, the common stationarity assumption in FC does not satisfactorily explain the dynamic process of...

Prior observations and studies suggest self-consciousness disorders in schizophrenia and Autism Spectrum Disorder (ASD), two neurodevelopmental disorders sharing social communication impairments. First, the relationships between schizophrenia and autism are explored regarding social communication impairments. Then, self-consciousness disorders in schizophrenia and autism are described and...

The Prefrontal Cortex (PFC) is one of the principal brain regions studied in consciousness. Previous investigations suggest that the PFC is an important neural hub in both awareness and the manipulation of the content of consciousness. Despite a consensus in the scientific community regarding PFC function in cortico-cortical networks, there is still intense debate as to its role in the...

Both psychedelics and meditation exert profound modulatory effects on consciousness, perception and cognition, but their combined, possibly synergistic effects on neurobiology are unknown. Accordingly, we conducted a randomized, double-blind, placebo-controlled study with 38 participants following a single administration of the psychedelic psilocybin (315 μg/kg p.o.) during a 5-day mindfulness...

Recent research in functional genomics shows that social stressors affect the expression of immune response genes. These effects are mediated in part via our adaptive capacity for intracellular molecules to respond to extracellular signals, a process called signal transduction. Under this framework, one way stressors can be transduced into cellular changes is through central nervous system...

Over the past 2,500 years, contemplative traditions have explored the nature of the mind using meditation. More recently, neuroimaging research on meditation has revealed differences in brain function and structure in meditators. Nevertheless, the underlying neural mechanisms are still unclear. In order to understand how meditation shapes global activity through the brain, we investigated the...

The stream of human consciousness persists during sleep, albeit in altered form. Disconnected from external input, the mind and brain remain active, at times creating the bizarre sequences of thought and imagery that comprise "dreaming." Yet despite substantial effort toward understanding this unique state of consciousness, no reliable neurophysiological indicator of dreaming has been...

An altered sense of the experience of time represents one of the nine dimensions that is conceived as characterizing a state of flow. While a number of other factors necessarily contribute to this overall experience of flow, subjective time perception is of particular quantitative interest and thus serves as the focus of the present meta-analysis. The extant body of relevant quantitative...

¿Cómo habitar, con nuestro cuerpo sensible y empático, un entorno descrito por un texto? El presente artículo explora dicha cuestión a partir de una serie de investigaciones desarrolladas a lo largo de las últimas décadas en el ámbito de las neurociencias en torno a la cognición encarnada y los estados alterados de consciencia. A partir de las investigaciones mencionadas, trataremos de...
