Investigating Cooperative Behavior in Ecological Settings: An EEG Hyperscanning Study.

The coordinated interactions between individuals are fundamental for the success of the activities in some professional categories. We reported on brain-to-brain cooperative interactions between civil pilots during a simulated flight. We demonstrated for the first time how the combination of neuroelectrical hyperscanning and intersubject connectivity could provide indicators sensitive to the humans' degree of synchronization under a highly demanding task performed in an ecological environment.

Evaluation of cortical imaging techniques based on somatosensory evoked potentials.

In the present study we evaluate the performance of several inverse algorithms for reconstructing the cortical current density distributions from scalp EEG recordings. The direct cortical SEP recordings in a patient were used as a gold standard to assess the performance of the numerical algorithms. The present results suggest that L(1)-norm methods gave the most accurate results in terms of cortical current density imaging of brain responses invoked by somatosensory stimulation.

Evaluation of cortical current density imaging methods using intracranial electrocorticograms and functional MRI.

Objective: EEG source imaging provides important information regarding the underlying neural activity from noninvasive electrophysiological measurements. The aim of the present study was to evaluate source reconstruction techniques by means of the intracranial electrocorticograms (ECoGs) and functional MRI.

Methods: Five source imaging algorithms, including the minimum norm least square (MNLS), LORETA with L(p)-norm (p equal to 1, 1.
