If you’ve ever read an article about the “best ways to boost neuroplasticity” or scrolled through the “top 10 daily habits to rewire your brain,” you’ve already gotten a peek into an important and growing research area. The brain’s ability to rewire itself is called neuroplasticity, and your ability to learn, make new memories, and recover from injury all depend on it. But like many things in biology, it’s all about balance—finding that sweet spot between too much and too little.  So how does your brain know how flexible to be, and how does that flexibility fluctuate throughout your life? What cells, genes, and molecules control the stability of your brain circuitry? Could we one day use this information to enhance our neuroplasticity in adulthood and help slow brain aging?  In Salk’s Year of Brain Health, we’re exploring the biology behind long-term cognitive health and finding practical interventions to prevent cognitive decline. When it comes to topics such as neuroplasticity, we’re digging deep to understand their complex mechanisms so that future therapeutic and lifestyle interventions can be as effective and personalized as possible. That all starts with studies such as those being done by Salk neuroscientist Nicola Allen, PhD. She and…
