Breakthrough Could Enable Others to Watch Your Dreams and Memories [Video]

Scientists at the University of California, Berkeley, have reconstructed the internal “movie” that plays in a person’s head. To re-create dynamic visual experiences, they used functional magnetic resonance imaging (fMRI) to measure the brain activity of volunteers (the other members of the research team) as they watched short movie clips (left panel in the video [...]

Cell phone emissions change brain metabolism

man on cell phone, brain activity metabolism change

Cell phones have not been convincingly linked to brain cancer, but that doesn’t mean that their associated radiation has no effect on our bodies. A new study shows that these pervasive devices can alter the brain’s glucose metabolism, a marker of neuronal activity. The findings will be published in the February 23 issue of JAMA, [...]

A “better brains” collective launches to improve cognition of the masses

Michael Merzenich is a pioneer in the exploration of neuroplasticity, the exploration of the brain’s intrinsic changeability, even in adulthood. In recent years Merzenich has brought neuroplasticity to the masses by forming a company, Posit Science, that uses the findings of his research to provide games that enhance visual and auditory skills. Now Posit wants [...]

New evidence that fMRI experiments are valid measure of neuron activity

fmri brain scan validation stimulation region brain activity

Among the more than a quarter of a million published functional magnetic resonance imaging (fMRI) studies are assays that have purported to locate our mental experiences of religion, love and even the future in the brain. Recently, researchers even investigated the reliability of the scans to find out whether they should hold up in court [...]
