Researchers have developed a new mapping tool that can be regarded as a breakthrough in the field of brain health. According to a study, a new laser- based imaging tool has been invented which can map the effects of drugs on the network of blood flow to the brain. This new technique is an advanced version of a method called Optical Coherence Doppler Tomography (ODT) where laser light hits the moving blood cells and bounces back. The researchers carried out their experiments on mice to observe how cocaine affects blood vessels in the brain.
The images revealed that after 30 days of chronic cocaine injection, there was a dramatic drop in the blood flow speed. It was for the very first time that a team of experts were able to identify cocaine-induced micro ischemia, when blood flow is shut down - a precursor to a stroke. "The resulting images are the first of their kind that directly…
