The Brain May Actually Keep Generating New Cells Well Into Old Age

Scientists have long been divided over whether neurogenesis—a process involving the growth of new neurons—continues into adulthood. Last year, a controversial study published in the journal Nature posited that humans stop generating new cells in the learning- and memory-centered hippocampus region long before reaching adolescence. Now, research published in Nature Medicine shifts the debate back in favor of late-in-life neurogenesis: As Sharon Begley reports for STAT, the latest findings suggest humans are actually capable of producing fresh cells well into their 90s.

Mosquitoes Can Smell Your Sweat

When a mosquito lands and your arm and starts taking a drink, it’s not just an unhappy accident. Mosquitoes use an array of chemical neuroreceptors to track down their next blood meal. Now, researchers have identified a key receptor that detects the lactic acid in human sweat, a finding that could eventually help people avoid becoming fast food for the insects.

Could This Brain Implant Stop Epilepsy Seizures?

For many people who suffer from neurological disorders, such as epilepsy, there are no viable treatment options. In our latest research, we developed an implantable device that may one day offer relief. We show that the implant can treat problems in the brain, such as epileptic seizures, by delivering brain chemicals – known as neurotransmitters – directly to the cells in the brain that cause the problem. Continue reading Could This Brain Implant Stop Epilepsy Seizures?

Maybe Our Brains Actually Can Grow Back Neurons

A new study published Thursday in Cell Stem Cell is set to further stoke the debate over whether our brain can actually grow back neurons as we age. The research found that people, even into their golden years, are regenerating their stock of neurons right up until the point of death—seemingly contradicting the results of a major study released just last month. Continue reading Maybe Our Brains Actually Can Grow Back Neurons

Unraveling the Genetics Behind Why Some People “See” Sound and “Hear” Color

It’s difficult to imagine for many people, but for a certain percentage of the human population, music may evoke colors, words stir up flavors or sounds may even curl into shapes. This mash-up of senses is known as synesthesia and has baffled scientists for decades. Now, reports Michael Price at Science, researchers have identified some of the genes that may be responsible for these unusual experiences.
