Intersubject consistency of cortical EEG signal during movie viewing with positive and negative emotional content

Neurophysiological research of emotions
during movie viewing
Neuroscience
Brain as a main source of information about emotions
Important for:
Neuromarketing
Neurobiology of emotion
Neuroscience of film
Previous study:
Neural reliability
Complexity of emotions
Films – naturalistic stimuli
Dmochowski study – breakthrough*

The main goal of research
Research questions:
How consistency is represented in our brain?
ISC – good marker of emotional state?
Aims:
