The 2026 Gruber Neuroscience Prize will be awarded to John L.R. Rubenstein, MD, PhD, of the University of California San Francisco, for his pioneering work on mammalian forebrain development, a structure which is responsible for functions such as cognition, memory and perception. This work has helped shed light on causes of multiple neurological and psychiatric disorders. These discoveries have led him and collaborators to develop a novel therapeutic approach in which cortical interneurons are transplanted into the hippocampus of patients with intractable focal epilepsy. Initial clinical trials have already yielded encouraging results.

Rubenstein’s research led to the discovery of the transcription factors that direct the development of excitatory and inhibitory neurons in the developing forebrain. Rubenstein, along with his collaborators, were able to elucidate the spatial and temporal dynamics of forebrain patterning, which included the discovery that inhibitory neurons generated in the basal ganglia, after which a subset migrate to the hippocampus and cortex.

Rubenstein and his collaborators then characterized the molecular pathways responsible for neuronal cell type specification, which included identifying the regulatory sequences, called enhancers, which transcription factors bind to, in order to direct gene expression.

“We are proud to present Rubenstein the 2026 Neuroscience Prize for a number of reasons,” says Joshua Sanes, Jeff C. Tarr Professor of Molecular and Cellular Biology at Harvard and chair of the Selection Advisory Board to the Prize. “Rubenstein’s work has led to an understanding of how the mammalian forebrain develops, which includes elucidating the transcription factors and regulatory sequences that are involved in forebrain patterning. This work has also led to a greater understanding of developmental conditions such as epilepsy and autism spectrum disorder.”

The Gruber Neuroscience Prize, which includes a $500,000 award, will be presented to Rubenstein on November 15 at the Annual Meeting of the Society for Neuroscience in Washington DC.

In addition to the cash award, the recipient will receive a gold laureate pin and a citation that reads:

The Gruber Foundation proudly presents the 2026 Neuroscience Prize to John L. R. Rubenstein for his groundbreaking research on the development of the mammalian forebrain, which is responsible for myriad functions, including cognition, memory, and perception.

Rubenstein began by identifying transcription factors that act as master developmental regulators of cortex and other forebrain areas. He then used elegant genetic approaches to probe mechanisms by which these factors regulate formation and disparate origins of excitatory and inhibitory neurons, and their patterning into discrete areas, layers and nuclei. He went on to characterize molecular programs underlying neuronal type specification by identifying the regulatory sequences, called enhancers, that bind transcription factors to control gene expression.

A physician-scientist, Rubenstein has used his discoveries as an entry point for analyzing brain disorders such as autism and epilepsy. Recently, he worked with colleagues to devise a revolutionary therapeutic approach to refractory epilepsy, based on the transplantation of cortical interneuron stem cells.
