Living Brain Project

Led by Alexander Charney, MD, PhD, and Brian Kopell, MD, the Living Brain Project is a multiscale, data-driven investigation of the living human brain that uses the full human-subjects neuroscience toolkit to discover how interactions among the various levels of neurobiology, neurophysiology, and neuroanatomy give rise to neuropsychiatric functioning. The toolkit includes clinical observation, neuropharmacology, neuroimaging, neurophysiology, neuromodulation, and molecular-cellular neuroscience.

Nash Family Center for Advanced Circuit Therapeutics

Under the guidance of founding director Helen S. Mayberg, MD, the Nash Family Center for Advanced Circuit Therapeutics collaborates with the Center for Neuromodulation to develop bold, new approaches for the treatment of conditions from major depression and addiction to eating disorders and post-traumatic stress syndrome to movement disorders and epilepsy as well. The Center synthesizes the skills of its research team with the insights of clinical colleagues in order to rethink the way treatments are discovered, personalized, and delivered to patients.

Brain Tumors

Our department has several research labs devoted to the study of brain tumors.

Comprehensive Brain Tumor Program

Isabelle Germano, MD, who leads the Comprehensive Brain Tumor Program, recently completed a multi-center trial using Optune—a device approved by the FDA in October 2015—for newly diagnosed glioblastoma (GBM), the most aggressive primary brain tumor. The results of our clinical trial showed that patients with newly diagnosed GBM who used Optune had longer time before tumor progression. More importantly, half of the people treated by Optune are alive two years post-treatment or longer.

Neurosurgery Oncology Program

Drs. Isabelle Germano, Saadi Ghatan, and Raymund L. Yong, MD, are active brain tumor surgeons involved with clinical trials and outstanding clinical care of brain tumor patients. Laser Interstitial Thermal Therapy (LITT) is now available throughout the Health System for the treatment of certain brain tumors that have relapsed despite surgery, radiation, and chemotherapy.

Radiosurgery Program

The Radiosurgery Program pioneered radiosurgery treatment for brain and spine cancer and tumors. A peer-reviewed paper: “Clinical outcome after single fraction spine radiosurgery for spinal metastasis” by Dr. Germano and colleagues, reports on the high tumor control rate and resolution of pain after single fraction spine radiosurgery for spinal metastasis. Radiosurgery is also performed at Mount Sinai West. Drs. Yong, Srivastava are actively involved with stereotactic radiosurgery treatment of patients. Close collaboration with Mount Sinai radiation oncologists, Drs. Sheryl Green and Walter Choi permits multidisciplinary care for patients requiring stereotactic radiosurgery.

The Brain Tumor Research Program

The Brain Tumor Research Program—comprised of Hongyan Zou, MD, Roland Friedel, PhD, Raymund Yong, MD, Dolores Hambardzyumyan, MD, MBA, and Isabelle Germano, MD—present their data weekly at a joint laboratory conference for the pursuit of collaborations and joint grant submissions on basic and translational research focusing on malignant brain tumors, specifically glioblastoma.

The Brain Tumor Molecular Genetics Laboratory

The Brain Tumor Molecular Genetics Laboratory is led by Raymund L. Yong, MD, and currently studies the evolutionary dynamics of glioma, the most malignant and complex primary brain tumor. The overall goal of the program is to identify new, modifiable, or even reversible, mechanisms of treatment resistance acquisition that might serve as the basis of future paradigm-shifting treatment strategies.

Laboratory of Axonal Growth and Neuronal Regeneration

The Axonal Growth and Neuronal Regeneration Laboratory, led by Hongyan Zou, MD, is currently NIH-funded. The lab currently studies how neurons originate, extend axons, and regenerate or fail to regenerate after mammalian CNS injury. In vivo axon injury models, neuronal cultures, molecular biology, and various imaging and tissue engineering techniques are used to study mechanisms that promote neurogenesis and axonogenesis.

Laboratory of Glioma Invasion and Stem Cells

Roland Friedel, PhD, is studying the mechanisms for glioma invasion and stem cell maintenance and is currently NIH-funded. His laboratory is involved with a mouse glioma model, which can be used to study oncogene amplification. His group has recently discovered new mechanistic insights in glioma progression.
