Résumé

The Perturbational Complexity Index (PCI) was recently introduced to assess the capacity of thalamocortical circuits to engage in complex patterns of causal interactions. While showing high accuracy in detecting consciousness in brain-injured patients, PCI depends on elaborate experimental setups and offline processing, and has restricted applicability to other types of brain signals beyond transcranial magnetic stimulation and high-density EEG (TMS/hd-EEG) recordings. We aim to address these limitations by introducing PCI PCI When calculated on TMS/hd-EEG potentials, PCI PCI

BACKGROUND
The Perturbational Complexity Index (PCI) was recently introduced to assess the capacity of thalamocortical circuits to engage in complex patterns of causal interactions. While showing high accuracy in detecting consciousness in brain-injured patients, PCI depends on elaborate experimental setups and offline processing, and has restricted applicability to other types of brain signals beyond transcranial magnetic stimulation and high-density EEG (TMS/hd-EEG) recordings.
OBJECTIVE
We aim to address these limitations by introducing PCI
METHODS
PCI
RESULTS
When calculated on TMS/hd-EEG potentials, PCI
CONCLUSIONS
PCI
