- Postdoctoral training, University College London (1962-1964)
Dr. Grinnell's primary research focuses on the neurophysiology of echolocating bats, specifically investigating the adaptations of the auditory nervous system that enable these animals to orient and hunt using echoes as a substitute for vision. His work explores bat echolocation behavior, feeding strategies, and the neural processing mechanisms underlying this remarkable sensory capability. Additionally, Dr. Grinnell has made significant contributions to understanding neuromuscular physiology, particularly the trophic influences between nerve and muscle that govern the number, size, and strength of nerve terminals. His research investigates the regulation of neurotransmitter release and the properties of presynaptic active zones, using experimental models including Xenopus nerve-muscle cell cultures and mature frog neuromuscular preparations.
Dr. Grinnell's publication record spanning over 60 years demonstrates consistent research productivity with recent work focusing on calcium dynamics at synaptic active zones and historical perspectives on echolocation research. His scientific approach bridges behavioral studies of bat echolocation with cellular and molecular investigations of neuromuscular transmission, revealing fundamental principles of sensory processing and neural communication.
Dr. Grinnell maintains a long-standing interest in the art and iconography of pre-Columbian ceramics from Central Panama, demonstrating his interdisciplinary approach to scientific and cultural inquiry. His academic leadership has shaped the Department of Integrative Biology and Physiology at UCLA through multiple directorships and chair positions over several decades.
Throughout his career, Dr. Grinnell has directed major research centers including the Jerry Lewis Neuromuscular Research Center and the Ahmanson Laboratory of Neurobiology, building and leading research teams focused on neurobiology and neuromuscular physiology. His laboratory work has pioneered techniques for simultaneous pre- and post-synaptic electrophysiological recording, contributing significantly to our understanding of synaptic transmission mechanisms.
