About Us Through deep interrogation of brain networks via brain imaging and clinical electrophysiology as well as sub-cellular networks using molecular and cellular analysis, we aim to move towards a better mechanistic understanding of these disorders. These findings should lead to better diagnostic and therapeutic approaches for patients with psychiatric disorders as well as fundamental new insights into the function of the human brain. Changes in the structure and function of the brain that result in mental illness are poorly understood. Neither do we know why some individuals are more prone to developing mental illness than others. Studying these underlying changes in the brain will likely lead to better methods to diagnose and treat mental illness. Our Objecti ves Investigate Psychiatric Disorders & Establish Databases Establish and investigate a large cohort of families with severe psychiatric illnesses & healthy controls Establish an informative, digital database of research outcomes alongside a repository of biological samples Research Focus Understand the causes, connections and courses of severe psychiatric illnesses Explore potential interventions and treatments Advanced Techniques Employ advanced techniques in imaging, genetics, and stem cell biology towards understanding the cellular and molecular mechanisms behind these disorders Open Source and Collaboration Commit to openness and collaboration by making the database and repository open-source Emphasise public engagement and community outreach Nodal Centres Department of Psychiatry, National Institute of Mental Health and Neurosciences The National Institute of Mental Health and Neurosciences (NIMHANS) is a world-renowned, multi-disciplinary centre for patient care, academics and cutting-edge research in the field of mental health and neuroscience. With its history dating back to 1847, the Central Government recognized its eminent academic position, growth and contributions, and declared it a ‘Deemed University’ in 1994. In 2012, NIMHANS was conferred the status of an ‘Institute of National Importance’. National Centre for Biological Sciences The National Centre for Biological Sciences (NCBS), located in Bangalore, is part of the Tata Institute of Fundamental Research. Established in 1992, It is a premier research institute with research interests of faculty members lying in the frontier areas of biology, and the science at NCBS (a part of the Tata Institute of Fundamental Research) uses experimental and computational approaches in the study of molecules, cells and organisms.
