[HTML][HTML] The strength of weak integrated information theory

…, FE Rosas, D Bor, AK Seth, AB Barrett - Trends in cognitive …, 2022 - cell.com
The integrated information theory of consciousness (IIT) is divisive: while some believe it

Granger causality and transfer entropy are equivalent for Gaussian variables

L Barnett, AB Barrett, AK Seth - Physical review letters, 2009 - APS
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 …

Multivariate Granger causality and generalized variance

AB Barrett, L Barnett, AK Seth - Physical review E, 2010 - APS
Granger causality analysis is a popular method for inference on directed interactions in
complex systems of many variables. A shortcoming of the standard framework for Granger …

[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

SN Garfinkel, AB Barrett, L Minati, RJ Dolan… - …, 2013 - Wiley Online Library
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 …
