Ehud Isacoff

Research Bio

Ehud (Udi) Isacoff is a neuroscientist and biophysicist whose research probes the molecular and cellular basis of brain function, with a particular focus on synaptic signaling, sensory perception, and circuit dynamics. By combining advanced imaging, electrophysiology, and genetic engineering, Isacoff’s lab explores how neural circuits process information and adapt to experience.

Isacoff is renowned for developing fluorescent sensors that visualize and control neurotransmission in real time, enabling new insights into how neurons communicate. His research has advanced understanding of learning and memory, sensory integration, and neurological disorders at both molecular and systems levels.

A leader in neurotechnology and synaptic biology, Isacoff is a professor in the Departments of Neuroscience and Molecular and Cell Biology at UC Berkeley, where he also serves as Director of the Helen Wills Neuroscience Institute and  Berkeley's component of Weill Neurohub, which joins with UCSF, University of Washington and the Allen Brain Institute to bring discoveries and new technologies of neuroscience to the clinic. Isacoff is a member of the National Academy of Sciences.

Weill Neurohub will fuel race to find new treatments for brain disease

With a $106 million gift from the Weill Family Foundation, UC Berkeley (Berkeley), UC San Francisco (UCSF) and the University of Washington (the UW) have launched the Weill Neurohub, an innovative research network that will forge and nurture new collaborations between neuroscientists and researchers working in an array of other disciplines—including engineering, computer science, physics, chemistry, and mathematics—to speed the development of new therapies for diseases and disorders that affect the brain and nervous system.

With single gene insertion, blind mice regain sight

University of California, Berkeley, scientists inserted a gene for a green-light receptor into the eyes of blind mice and, a month later, they were navigating around obstacles as easily as mice with no vision problems. The researchers say that, within as little as three years, the gene therapy — delivered via an inactivated virus — could be tried in humans who’ve lost sight because of retinal degeneration, ideally giving them enough vision to move around and potentially restoring their ability to read or watch video.

New therapy holds promise for restoring vision

A new genetic therapy developed by UC Berkeley scientists has not only helped blind mice regain light sensitivity sufficient to distinguish flashing from non-flashing lights, but also restored light response to the retinas of dogs, setting the stage for future clinical trials of the therapy in humans. The therapy involves inserting photoswitches into retinal cells that are normally ‘blind.’

On Memory’s Trail

Neural circuit ensures zebrafish will not bite off more than it can chew

UC Berkeley neuroscientists have found that when zebrafish larvae see large objects, like leaves or other zebrafish, inhibitory nerve cells fire in the brain to tamp down a prey response. But when the larvae see small, prey-size objects, fewer inhibitory nerve cells fire and the fish quickly responds. This simple neural circuit helps explain the visual filters that enable prey capture.

UC Berkeley gene therapy breakthrough could help cure blindness, researchers say

Using a new and relatively simple gene-therapy treatment, Berkeley scientists have restored enough sight in previously blind mice that within a month they were navigating their environment with the same ease as sighted mice. The treatment involved just one injection of a gene for a green-light receptor into the eyes. "With neurodegenerative diseases of the retina, often all people try to do is halt or slow further degeneration," says molecular and cell biology professor Ehud Isacoff, director of the Helen Wills Neuroscience Institute and one of the study's co-authors. "But something that restores an image in a few months -- it is an amazing thing to think about." The findings offer hope to roughly 170 million people around the world with age-related macular degeneration, and 1.7 million people with a common form of inherited blindness, called retinitis pigmentosa. The team is now raising money to begin human trials in the next three years. For more on this, see our press release at Berkeley News.
