A professor of psychology at Laurentian since 1971, Persinger is perhaps best-known for the development of the "God Helmet," a device used to study creativity, religious experiences, and the effects of stimulation of the temporal lobes.
In February 2007, he was asked to vacate three testing rooms at Laurentian's animal care facility, due to a shortage of research space on the campus.
At the time, Persinger's students filed a lawsuit against the university for locking them out of the research space and he filed a grievance with the faculty association to remedy the situation.
Despite his feuds with Laurentian's administration over the years, Persinger has also been recognized for his teaching style.
Persinger made national news headlines in 2016 when he was removed from a course by the university because of a form he had students sign, warning them that they would encounter some words and language that they may find offensive.
An online petition was started to re-instate Persinger, which garnered hundreds of signatures and positive comments from students who believed he was being treated unfairly.
