Machines Close to 'Seeing' the Movies in our Minds
Berkeley scientists say with MRI and computer models they can reconstruct our visual experiences, paving the way to reproduce our mental movies, such as dreams and memories.
What's the Latest Development?
Imagine watching someone’s dream, or tapping directly into the mind of a coma patient. Berkeley scientists say they're close to doing it via fMRI and computational models which decode and reconstruct people’s dynamic visual experiences. So far, the technology only reconstructs movie clips you’ve already viewed. But the breakthrough paves the way to reproduce our mental movies no one else sees, such as dreams and memories.
What's the Big Idea?
The researchers say that eventually the technology could allow us to see into the minds of people who cannot communicate verbally, such as stroke victims, coma patients, and people with neurodegenerative diseases. It may also lay the groundwork for a brain-machine interface, so people with cerebral palsy or paralysis, for example, can guide computers with their minds.
There's a growing understanding that drawing is much more than an art form: it's a powerful tool for learning.
- We often think of drawing as something that takes innate talent, but this kind of thinking stems from our misclassification of drawing as, primarily, an art form rather than a tool for learning.
- Researchers, teachers, and artists are starting to see how drawing can positively impact a wide variety of skills and disciplines.
- Drawing is not an innate gift; rather, it can be taught and developed. Doing so helps people to perceive the world more accurately, remember facts better, and understand their world from a new perspective.
It may be simpler than we thought.
- An analysis of a massive amount of data reveals four new personality types.
- The study is the first to take self-reporting out of the equation.
- The four new types are "average," "reserved," "self-centered," and "role model".
Despite its prominence in our collective imagination, variations in metabolism play a minor role in obesity.
- Vox senior health correspondent Julia Belluz spent a day inside of a metabolic chamber at the National Institutes of Health Clinical Center.
- Her 90 minutes on stationary cycle only burned 405 calories, just 17% of the day's total calories.
- Resting metabolism uses up the bulk of the body's energy.
