IIT Mandi invents new technique to detect abnormal brain activity By IANS | 5 Views Everything you need to know about a brain stroke.. Image Source: IANS News Mandi : , May 3 (IANS) Researchers at the Indian Institute of Technology (IIT) Mandi have invented a method to simultaneously study the variations in nerve functions and brain blood flow associated with brain disorders such as ischemic stroke. The method will help locate and classify the damaged sites (lesions) in the brain, brought about by or leading to neurological diseases. It is based on the fact that intricate interactions between nerve cells (neurons) and blood vessels (vasculature), called the NeuroVascular Coupling (NVC), regulates blood flow in the brain. Diseases such as ischemic stroke adversely affect the NVC. When the nerve impulses do not trigger the required blood flow, it results in NVC. Timely detection of NVC is critical for the prevention, diagnosis and treatment of such diseases.
