Clinical Trial Summary

This monocentric physiological study will evaluate the neural bases of visual recognition of emotions in stroke patients vs. healthy controls using MRI (functional and structural connectivity) and EEG.

Description:

This monocentric physiological study will evaluate the neural bases of visual recognition of emotions in stroke patients vs healthy controls (2 groups of 40 subjects). It will include functional MRI, structural MRI (disconnectome), EEG, and behavioral assessments of emotion recognition and executive functions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	BOLD signal when fear visual recognition	Compare correlations of cerebral functional activations (BOLD) by fMRI between groups when stimulus = fear	1 day
Secondary	BOLD signal when happiness visual recognition	Compare correlations of cerebral functional activations (BOLD) by fMRI between groups when stimulus = happiness	1 day
Secondary	Electrical connectivity (EEG) when fear visual recognition	Compare cerebral networks activated by a fear visual task recognition in both groups	1 day
Secondary	Electrical connectivity (EEG) when fear happiness visual recognition	Compare cerebral networks activated by a happiness visual task recognition in both groups	1 day
Secondary	Electrical connectivity (EEG) when emotions auditory recognition	Compare cerebral networks activated by an auditory task recognition in both groups	1 day
Secondary	Relationship between behavioral performance and cerebral networks	Correlations between fMRI and EEG networks vs. behavioral performance (emotion recognition)	1 day
Secondary	Structural connectivity	Disconnectome maps in the stroke patients group	1 day
Secondary	Relationship between emotional self-assessment and cerebral networks	Correlation between the ESQ (emotional state questionnaire) and cerebral connectivity (EEG) and fMRI networks	1 day
Secondary	Relationship between the behavioural performance in emotion recognition and executive functions	Correlation between behavioral performance in emotion recognition (Eckman Test) and executive functions (Stroop Test) in the stroke group	1 day
Secondary	Relationship between lesion characteristics and the behavioral performance in emotion recognition	Correlation between lesion volume and the behavioural performance in emotion recognition (Eckman Test)	1 day
