How to reprogram memory cells in the brain

Long-term memory of specific places is stored in the brain in so-called place cells. Neuroscientists have now ‘reprogrammed’ such place cells in free-roaming mice, by sending electrical impulses directly to individual neurons.

Reorganization of brain outputs in deaf cats

Cats deaf from an early age have increased outgoing connections from the auditory cortex to a midbrain region responsible for directing the animal to a particular location in its environment. The study is the first to examine the reorganization of outp…

Novel PET imaging agent could help guide therapy for brain diseases

Researchers have developed a new PET imaging agent that could help guide and assess treatments for people with various neurological diseases, including Alzheimer’s, Parkinson’s, and multiple sclerosis. The agent targets receptors in nerve cells in the …

Do you fear embarrassment? Here’s how to overcome it
