To answer your question, you need to know who was head of the Scottish Rites in NY at the time. That would be Dr. Nolan Lewis. He was also Chairman of the Colombia University Psychiatry department, and interested in the study of brain chemistry relating to mental illness and dementia. Freemasons are often tasked to raise money for medical research. Shriners are known for their burn treatment research fund raisers, for example. In this instance Scottish Rites was tasked with raising the money necessary for this and other research. It is no mystery that findings would be presented to them.
Dig Dr. Nolan Lewis, Columbia for a wealth of information.
