Traumatic Brain Injury: From Molecule to Mind

Our mission: To understand basic mechanisms relevant to developing effective approaches for treating traumatic brain injury.

Introduction

Traumatic Brain Injury (TBI) is a serious medical problem that has only recently come into the public eye, primarily as a result of combat blast-related injuries in Iraq and Afghanistan, but it has long been under recognized as a public health problem in the U.S., with an estimated 1.7 million people affected annually. Symptoms may include impairments in memory, concentration, sleep, and mood, as well as seizures, and can persist for many years. There are currently no treatments that directly target damage to the brain in TBI.

Recent advances in Neuroscience, from basic findings at the level of genes and molecules, to cells and circuits, and up to human brain imaging, offer new possibilities for the development of effective therapies for brain disorders. In particular, findings on nerve growth and regeneration, as well as on the function and self-organization of circuits involved in higher cognitive functions, provide a starting point for addressing the specific pathology associated with TBI. Under the aegis of the Kavli Institute for Brain and Mind (KIBM) at UCSD, we have assembled an interdisciplinary team of exceptional scientists representing each of these levels of research as well as clinical research and practice. Working together in close coordination, our goal is to bring the benefit of current neuroscientific understanding to bear on the problem of TBI.

Our Research Program

Our research focuses on identifying the nerve circuits that are most critical in the deficits produced by TBI, and on the molecular mechanisms in these nerve cells that may provide a path towards repairing the damage.
