Consciousness science is marred by disparate constructs and methodologies, making it challenging to systematically compare theories. This foundational crisis casts doubts on the scientific character of field itself. Addressing it, we propose a framework for comparing consciousness theories introducing novel inter-theory classification interface, Measure Centrality Index (MCI). Recognizing its gradient distribution, MCI assesses degree importance specific empirical measure has given theory. We apply probe how measures Global Neuronal Workspace Theory (GNW), Integrated Information (IIT), Temporospatial (TTC) would fare within context other two. demonstrate that direct comparison IIT, GNW, TTC meaningful valid some like Lempel-Ziv Complexity (LZC), Autocorrelation Window (ACW), possibly Mutual (MI). In contrast, problematic others anatomical physiological neural correlates (NCC) due their MCI-based differential weightings structure sum, introduce provide proof-of-principle systematic method comparisons, thereby addressing isolated evolution confirmatory bias issues in state-of-the-art neuroscience consciousness.

Brain and breathing activities are closely related. However, the exact neurophysiological mechanisms that couple brain to stimuli in external environment not yet agreed upon. Our data support synchronization dynamic attunement two key local activity periodic stimuli. First, we review existing literature, which provides strong evidence for of terms coherence, cross-frequency coupling phase-based entrainment. Second, using EEG data, show both lungs localized at Cz channel attune temporal structure their power spectra auditory inputs. We highlight role playing a coordinating tripartite alignment activity, input dynamics across longer timescales like minutes. Overall, this perspective sheds light on potential brain-breathing its environment.

Anxiety is a pervasive emotional state where, phenomenologically, subjects often report changes in their experience of time and space. However, systematic quantified examination space terms self-report scale still missing which eventually could also be used for clinical differential diagnosis. Based on historical phenomenological literature patients' subjective reports, we here introduce, first step, the Scale Time Space Experience (STEA) smaller sample 19 with anxiety disorders and, second validate its shorter version (cSTEA) larger 48 subjects. The main findings are (i) high convergent divergent validity STEA both Beck Inventory (BAI) (r = 0.7325; p < 0.001) Depression (BDI) 0.7749; 0.0001), as well spontaneous mind wandering (MWS) 0.7343; deliberate (MWD) 0.1152; > 0.05), (ii) statistical feature selection shows 8 key items future usage focusing temporal spatial constriction, (iii) effects (i.e., cSTEA scores) level mediated by degree (MWS), (iv) allows differentiating levels from severity comorbid depressive symptoms, (v) significant reduction scores after therapeutic intervention (breathing therapy). Together, our study introduces novel fully highly valid instrument, STEA, measuring time-space experiences anxiety. Further develop assessing valid, quick, simple way diagnosis, monitoring

The human brain is tightly connected to the individual's environment and its input dynamics. How dynamics of periodic environmental stimuli influence neural activity subsequent behavior via entrainment or alignment not fully clear yet, though. This study explores how behavior. EEG data was collected during a Go-NoGo task with intertrial interval (ITI) 1.3 s (0.769 Hz). Results showed that task's temporal structure increased power spectrum at 0.769 Hz, which high intersubject variability. Higher task-periodicity effects were linked stronger phase-based coherence (ITC) reduced complexity, as measured by lower Lempel-Ziv Complexity (LZC). Additionally, higher periodicity in correlated faster reaction times response bias. We conclude encoding inputs' into brains shapes behavior, e.g., RT bias, through reducing complexity. examines affect from show influences brain's spectrum, complexity improving time

Loorits (2014) identifies the solution to hard problem of consciousness in possibility fully analyzing seemingly non-structural aspects structural terms. However, research on conducted recent decades has failed bridge explanatory gap between brain and conscious mind. One reason why cannot be filled, consequently remains hard, is that experience neural structure are too different or "distant" directly compatible. Conversely, can found phenomenal experience. possible alternative, therefore, seek not substrate, but within itself, through a analysis qualitative experience, starting from its simplest forms. An essential premise reformulate explanandum consciousness, which usually attributed qualia what it like certain state. these properties do allow us identify fundamental Sensations such as redness red painfulness pain inseparable context they belong, making appear artifacts. Furthermore, early vision. They involved perceptual organization necessarily have relational significance. The unitary set qualities vision-such those related being an object, background detail-constitutes forms seems imply justifying structure. Although vision characterized by interdependent components form whole, we find consciousness. Phenomenal appearance alone does seem sufficient closeness characteristics prompts delve into less explored territory, using also explanans.

Time delays are a signature of many physical systems, including the brain, and considerably shape their dynamics; moreover, they play key role in consciousness, as postulated by temporo-spatial theory consciousness (TTC). However, often not known priori need to be estimated from time series. In this study, we propose use permutation entropy (PE) estimate neural series more robust alternative widely used autocorrelation window (ACW). first part, demonstrate validity approach on synthetic data, show its resistance regimes nonstationarity Mirroring yet another example comparable behavior between different nonlinear entropy-time delay estimation (PE-TD) is also able measure intrinsic timescales (INTs) (temporal windows activity at rest) hd-EEG human data; additionally, replication extends abnormal prolongation INT values disorders (DoCs).
