Applying Illusions

The video discusses the challenges of treating epilepsy when surgery is required, highlighting the risks of affecting speech areas in the brain. The water test is a traditional method to determine cerebral dominance but is invasive. Alternatives like fMRI and MEG are less reliable. The octave illusion is presented as a promising non-invasive test, showing strong correlation with cerebral dominance in a study. The findings suggest it could replace or complement the water test, reducing the need for invasive procedures.

What alternative methods to the water test are mentioned, and how reliable are they?

What was the significance of the findings related to the octave illusion in predicting cerebral dominance?
