Functional magnetic resonance imaging or functional MRI (fMRI) is an MRI procedure that measures brain activity by detecting associated changes in blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.
As the writers on Nature depict it, it evokes the dystopian worlds of science fiction writer Philip K. Dick – if you’ve read his works or seen Minority Report, you’ll understand it. Neuroscientists have developed a brain scan that shows how likely are convicted felons to commit crimes again. Brain scanning felons Kent Kiehl, a [...]
As amazing as it sounds, communicating with a person in a vegetative state is no longer something we see in sci-fi movies, it is beginning to become a reality. A vegetative state occurs when some patients come out of a come and wake up, but not with their minds, just their bodies. While they are [...]
Psychedelic mushrooms have been used for medical, ceremonial and spiritual purposes for thousands of years, due their mind-alterating properties which induce hallucinations, perception disorders or altered states of awareness. It’s been found that the active ingredient responsible for the psychedelic state, which many associated with a religious experience, is a substance called psilocybin. Though a lot is [...]
Mixing in a typical fMRI brain scanner with advanced computer modeling simulations, scientists at the University of California have managed to achieve the the unthinkable – render the visual expressions triggered inside the brain and play them like a movie. This is the forefront technology which will one day allow us to tap inside the mind [...]
Researchers from Princeton University recently published a study in which they show how they’ve been able to use functional magnetic resonance imaging and a computer program that condensed 3,500 Wikipedia articles to associate words to particular brain activity patterns. Basically, they were able to read thoughts. To reach this remarkable correlation, researchers first did some [...]
