Brain discoveries open doors to new treatments

Brain-zapping implants that fight depression are inching closer to reality
Like seismic sensors planted in quiet ground, hundreds of tiny electrodes rested in the outer layer of the 44-year-old woman’s brain. These sensors, each slightly larger than a sesame seed, had been implanted under her skull to listen for the first rumblings of epileptic seizures.
The electrodes gave researchers unprecedented access to the patient’s brain. With the woman’s permission,...

Why it’s key to identify preschoolers with anxiety and depression
The task was designed to scare the kids. One by one, adults guided children, ranging in age from 3 to 7, into a dimly lit room containing a mysterious covered mound.

To understand the human brain, take note of the rare, the strange and the downright spooky. That’s the premise of two new books, Unthinkable by science writer Helen Thomson and The Disordered Mind by neuroscientist Eric R. Kandel.
Both books describe people with minds that don’t work the same way as everyone else’s. These are people who are convinced that they are dead, for instance;...

The study of human heredity got its start in insane asylums
Genetics in the MadhouseTheodore M. PorterPrinceton Univ., $35
England’s King George III descended into mental chaos, or what at the time was called madness, in 1789. Physicians could not say whether he would recover or if a replacement should assume the throne. That political crisis jump-started the study of human heredity.
Using archival records, science historian Theodore M...
