Dear Mr. Messa,
Thank you for posting your request on History Hub!
We located the following web page Neuroscience History Archives from the Brain Research Institute of the University of California, Los Angeles (UCLA). We suggest you review the available links within that page for topics relating to your research. The contact information for the Archivist, Russell A. Johnson, is firstname.lastname@example.org.
You may also find the National Library of Medicine to be an informative resource for historical collections regarding the subconscious mind and brain waves that are now in the public domain. The publications are available digitally.
We hope this is helpful. Best of luck in your research!
