Brainwaves Reveal IQ
What intelligence is and how to measure it are thorny questions. If the brain’s information processing power could be measured directly with medical instruments, then the problematic assumptions, cultural biases, and pitfalls of IQ tests could be avoided. Moreover, direct measurement of the brain’s information processing power could reveal how specific brain circuits boost intelligence…
Read MorePromise and Concerns of Reading and Controlling Minds with New Technology
The ability to detect electrical activity in the brain through the scalp, and to control it, will soon transform medicine and change society in profound ways. Patterns of electrical activity in the brain can reveal a person’s cognition—normal and abnormal. New methods to stimulate specific brain circuits can treat neurological and mental illnesses and control…

We know that Homo sapiens (meaning the wise one) co-inhabited the earth with Neandertals. What’s more, DNA analysis proves that men and women of both species (or subspecies if you prefer), mated. Of course, there was no Valentine’s Day back when the daily grind for a working man meant bringing down a woolly mammoth with a sharp stick.…

Brain imaging (MRI) shows anatomical changes inside children’s brains after prolonged TV viewing that would lower verbal IQ.
Read MoreSnakes on the Brain
After repeated encounters with a friendly rattlesnake last week I have snakes on the brain. Serpents are a storehouse of fascinating neuroscience. Infrared vision, venom, fast-twitch muscles to energize its “warning buzzer,” and more… The western diamondback rattlesnake can rattle its tail at frequencies of 90 Hz and do this continuously for hours. This is…
