TestimonialI was a Grass Fellow in 1968, just prior to starting an Assistant Professor position at Princeton University. The immersion in a broad, diverse neuroscience community afforded by my Grass Fellowship at the MBL changed by professional trajectory profoundly. I came to appreciate how much neuroscience I had yet to learn, which I rectified by teaching a neurophysiology course, with lab, at Princeton. The contacts I made among other Grass Fellows and among the summer neuroscience research community, provided an invaluable base on which to build. Having imprinted on the MBL that summer, I jumped at the chance to become a faculty member in the Experimental Invertebrate Neurobiology summer course at the MBL the following summer. In 1977 I morphed that course into the Neural Systems and Behavior course, with essential help from several former Grass Fellows as faculty.
