Gordon Murray Shepherd (born 1933) is a neuroscientist who has carried out basic experimental and computational research on how neurons are organized into microcircuits to carry out the functional operations of the nervous system. Using the olfactory system as a model that spans multiple levels of space, time and disciplines, his studies have ranged from molecular to behavioral, recognized by an annual lecture at Yale University on "integrative neuroscience". He is currently professor of neuroscience emeritus at the Yale School of Medicine.
