Abstract Scale-free physiological processes are ubiquitous in the human organism. Resting-state functional MRI studies observed loss of scale-free dynamics under anesthesia. In contrast, modulation during task-related activity remains an open question. We investigate cerebral cortex’s unimodal periphery and transmodal core topography rest task states three conscious levels (awake, sedation, anesthesia) complemented by computational modelling (Stuart-Landau model). The empirical findings...
The human brain's cerebral cortex exhibits a topographic division into higher-order transmodal core and lower-order unimodal periphery regions. While timescales between the region diverge, features of their power spectra, especially scale-free dynamics during resting-state mdulation in task states, remain unclear. To answer this question, we investigated ~1/f-like pink noise manifestation core-periphery topography rest states applying infra-slow inter-trial intervals up to 1 min falling...
Consciousness is constituted by a structure that includes contents as foreground and the environment background. This structural relation between experiential background presupposes relationship brain environment, often neglected in theories of consciousness. The temporo-spatial theory consciousness addresses brain–environment concept labelled ‘temporo-spatial alignment’. Briefly, alignment refers to brain's neuronal activity's interaction with adaption interoceptive bodily exteroceptive...
<h3>Background:</h3> Schizophrenia is hypothesized to involve a disturbance in the temporal dynamics of self-processing, specifically within interoceptive, exteroceptive, and cognitive layers self. This study aimed investigate intrinsic neural timescales (INTs) these self-processing among people with schizophrenia. <h3>Methods:</h3> We conducted functional magnetic resonance imaging (fMRI) INTs, as measured by autocorrelation window, schizophrenia healthy controls during both resting-state...
Working memory (WM) describes the dynamic process of maintenance and manipulation information over a certain time delay. Neuronally, WM recruits distributed network cortical regions like visual dorsolateral prefrontal cortex as well subcortical hippocampus. How input dynamics subsequent neural impact remains unclear though. To answer this question, we combined analysis behavioral capacity with measuring through task-related power spectrum changes, e.g., median frequency (MF) in functional...
Abstract Functional magnetic resonance imaging (fMRI) studies have demonstrated that intrinsic neuronal timescales (INT) undergo modulation by external stimulation during consciousness. It remains unclear if INT keep the ability for significant stimulus-induced primary unconscious states, such as sleep. This fMRI analysis addresses this question via a dataset comprises an awake resting-state plus rest and stimulus states We analyzed measured temporal autocorrelation supported median...
Abstract Neurophilosophy is a controversial scientific discipline lacking broadly accepted definition and especially well-elaborated methodology. Views about what neurophilosophy entails how it can combine neuroscience with philosophy, as in their branches (e.g. metaphysics, epistemology, ethics) methodologies, diverge widely. This article, first of all, presents brief insight into the naturalization philosophy regarding three resulting distinguishable forms may or not be connected part 1,...
