For neurons, birthday matters

How brain cells make their connections during development still isn’t well understood. A new study shows that in the eye, a neuron’s birthday makes a difference in how it finds its targets.

Computing

Brain-inspired computer chip mimics 1 million neurons

By processing data in parallel, computer chips modeled after the human brain could perform certain tasks, such as pattern recognition, faster and more energy-efficiently than traditional computers.

Long-term Parkinson’s treatment sheds bad rep

Prolonged used of levodopa doesn’t increase the severity of side effects from the Parkinson’s drug, new research shows.

Neuroscience

For rats, a break from stress isn’t worth the relief

An unplanned vacation from stress might seem like a good idea, but a new study in rats shows that unpredictable escapes from pressure produce more strain on the first day back.
