Wonders You Must Know

 Functional Magnetic Resonance Imaging, or fMRI, is an incredible technology that lets scientists observe the brain in action. fMRI enables us to see which parts of the brain are active during different thoughts, emotions, or actions. It has revolutionized our understanding of the mind and is used widely in research and medicine. Renowned figures like Alan Alda and Dr. Nancy Kanwisher at MIT have contributed to public awareness and understanding of fMRI. Alan Alda, through his science communication efforts, and Dr. Kanwisher, an MIT neuroscientist, have helped explain how fMRI opens windows into the brain’s complexities. How Does fMRI Scanning Work? At its core, fMRI measures brain activity by detecting changes in blood flow. The basic idea is simple: when a part of the brain is in use, it requires more oxygen. Blood rich in oxygen flows to active areas, and fMRI detects these changes using a method called BOLD (Blood Oxygen Level Dependent) contrast. An fMRI scan typically involve...

While it might seem like a rare occurrence, many people encounter this phenomenon throughout their lives. In this blog, we’ll delve into the details of jamais vu, exploring its causes, effects, and the science behind it. What is Jamais Vu?

While déjà vu is that fleeting sensation that a new experience feels oddly familiar, jamais vu is the experience of recognizing something familiar but feeling as though you are encountering it for the first time.
