Implantation of a “memory prosthesis” appears to improve memory in people with brain damage. As I wrote in September. The device is designed to mimic the way our brain normally forms memories in the shape of a seahorse called the hippocampus.
And a brain stimulation method that delivers gentle electricity through an electrode swimming cap appears to improve memory in older adults.As reported last year.
Electrodes implanted in the brains of people with depression are helping us better understand and treat the disease. A team has used a set of electrodes to develop a “mood decoder” that can detect when a person is entering a depressed state and reverse it.
It’s not just brain information that can be dangerous in the wrong hands. My colleague Tanya Basu has a guide to keeping track of your menstrual health data in a post-Ro the world.
