[HTML][HTML] The strength of weak integrated information theory
The integrated information theory of consciousness (IIT) is divisive: while some believe it
provides an unprecedentedly powerful approach to address the ‘hard problem', others dismiss …

[HTML][HTML] Knowing your own heart: distinguishing interoceptive accuracy from interoceptive awareness
Interoception refers to the sensing of internal bodily changes. Interoception interacts with
cognition and emotion, making measurement of individual differences in interoceptive ability …

Granger causality and transfer entropy are equivalent for Gaussian variables
Granger causality is a statistical notion of causal influence based on prediction via vector
autoregression. Developed originally in the field of econometrics, it has since found application …

Greater than the parts: a review of the information decomposition approach to causal emergence
Emergence is a profound subject that straddles many scientific disciplines, including the
formation of galaxies and how consciousness arises from the collective activity of neurons. …

[HTML][HTML] Granger causality analysis in neuroscience and neuroimaging
A key challenge in neuroscience and, in particular, neuroimaging, is to move beyond
identification of regional activations toward the characterization of functional circuits underpinning …

[HTML][HTML] Increased spontaneous MEG signal diversity for psychoactive doses of ketamine, LSD and psilocybin
What is the level of consciousness of the psychedelic state? Empirically, measures of neural
signal diversity such as entropy and Lempel-Ziv (LZ) complexity score higher for wakeful …

[HTML][HTML] Practical measures of integrated information for time-series data
AB Barrett, AK Seth - PLoS computational biology, 2011 - journals.plos.org
A recent measure of ‘integrated information’, Φ DM , quantifies the extent to which a system
generates more information than the sum of its parts as it transitions between states, possibly …

What the heart forgets: Cardiac timing influences memory for words and is modulated by metacognition and interoceptive sensitivity
Mental functions are influenced by states of physiological arousal. Afferent neural activity
from arterial baroreceptors at systole conveys the strength and timing of individual heartbeats …

Measures of metacognition on signal-detection theoretic models.
Analyzing metacognition, specifically knowledge of accuracy of internal perceptual, memorial,
or other knowledge states, is vital for many strands of psychology, including determining …
