Thesis Art: Lisa-Marie Vortmann

I was a supervisor for Lisa-Marie Vortmanns’s Master’s Thesis.

In her project, we tried to decode from brain activity* which objects on a screen a subject is currently tracking with their mind. To do this, we “tagged” the to-be-tracked objects and distractor with different frequencies, so that we can trace them in the EEG. What you see here is the SSVEP response over time for three trials per row. At the beginning and end, the response is small because the object was not tracked, only in the middle part one can see that the response is much larger, the object was tracked. The plot is “written” by the first 10.000 letters of Lisa’s Thesis.

* This is actually Lisa’s own brain activity
