Lawrence R. Edelstein, Ph.D. is a neuroscientist and pharmaceutical industry consultant with research interests in multisensory convergence/integration (claustrum) and intercellular communication (exosomes, telocytes). His interest in exosomes was fueled by a theme issue he guest-edited with John Smythies and Denis Noble entitled “Epigenetic information-processing mechanisms in the brain? (2014; https://royalsocietypublishing.org/toc/rstb/369/1652). That undertaking proved to be the impetus for a series of peer-reviewed articles in which he and his colleagues theorized as to the whys and wherefores of the multifunctional roles played by seemingly omnipresent and phyla-agnostic exosomes. In addition, Dr. Edelstein is co-editor (along with John Smythies and Vilayanur S. Ramachandran, M.B.B.S., Ph.D., Hon. F.R.C.P.) of the book Claustrum - Structural, Functional and Clinical Neuroscience (2014; www.elsevier.com/books/the-claustrum/smythies/978-0-12-404566-8).
