Слайд 3The main goal of research
Research questions:
How consistency is represented in our
brain?
ISC – good marker of emotional state?
Aims:
Identify Intersubject Correlation (ISC)
Show neural reliability of emotional states
Practical purpose:
Develop a new method of tracking emotions

Слайд 6Correlation between EEG components in positive emotions
Low level of neural reliability
in negative emotions
Questionnaire will show difference between positive and negative movies
ISC – good marker of emotional state
