Researchers at the University of Illinois Urbana-Champaign report that extracellular vesicles released into the bloodstream ...

Exercise strengthens both the body and the mind, and researchers are uncovering the molecular messengers that make the connection. The messengers can also be transferred from an active mouse to a ...

Memory impairment and mood changes are typically observed in patients with Alzheimer’s disease but what disturbs these neuronal functions is unclear. Some researchers have proposed that alterations in ...

For over a decade, neuroscientists have been trying to figure out how neurogenesis (the birth of new neurons) and neuroplasticity (the malleability of neural circuits) work together to reshape how we ...

In mammalian adult brains, neural stem cells are only present in few specific parts, so called niches. Only these niches are capable of generating new neurons. For the first time, researchers defined ...

Fifteen years ago, the discovery of adult neurogenesis (the production of new neurons) in the highly static, non-renewable mammalian brain was a breakthrough in neuroscience. Now new neuronal ...

Scientists once thought that mammals entered adulthood with all of the neurons they would ever have, but studies from the 60s found that new neurons are generated in certain parts of the adult brain ...
