Computer algorithm, MRI used to tap memory

A computer algorithm, functional Magnetic Resonance Imaging (fMRI), and neuroscientists working together have been able to identify what people are remembering by measuring blood flow levels, according to new research out of the University College London.

First, a group of 10 volunteers (average age 21) was shown three very short (as in 7 seconds) films, each of a woman on a city street doing a simple task, such as mailing a letter. Then, each of the volunteers was placed inside an fMRI scanner and asked to recall each film, first in a specific order, then at random.

Robotic cockroaches and electronic babysitters

The New York Times reported last week that led by robots, roaches abandon [their] instincts. Specifically, when left to their own devices, groups of cockroaches followed their instincts and natually preferred a darker hiding place to a lighter hiding place virtually all the time. And when a minority group of robotic cockroaches replaced some of the bugs in the cohort and followed natual cockroach rules, again virtually all cockroaches sought the darker hiding place. But when the robots were programmed to seek the lighter, rather than a darker hiding place, fully 60 percent of the wild cockroaches teamed with the robots rather than obeying their instincts, thus demonstrating that even cockroaches are susceptible to bug peer pressure.… Read more
