Medical Xpress: Researchers track the birth of memories

How and when the ability to form and store memories arises are topics of great interest to neuroscientists. Now Yale researchers have identified three distinct stages in brain development that occur before episodic memories can form.Yale scientists measured brain activity in the hippocampus of newborn rats and found at the beginning of third week of […]

MIT News: Scope advance gives first look through all cortical layers of the awake brain

Just like doctors seek to scan deeper into the body with sonograms, CT, and MRI, and astronomers seek to look farther out into the universe with space-based telescopes, adaptive optics, and different wavelengths of light, neuroscientists pursue new ways to watch brain cells at work deep inside the brain. Three-photon microscopy recently emerged to give […]

Health Day: Stroke, heart events can sideline you from work

After having a stroke, heart attack or cardiac arrest, people are less likely to be employed than their healthy peers, new research shows. Even if they are working, they may earn significantly less than people who haven’t had a stroke or heart event, the investigators found. Although the majority of people who have one of […]

Futurity: Bad sleep in older adults may signal Alzheimer’s disease

Elevated tau, a sign of Alzheimer’s disease, links to brain damage and cognitive decline. Poor sleep is a hallmark of Alzheimer’s disease. People with the disease tend to wake up tired and worsening memory loss make nights even less refreshing. But how and why restless nights are linked to Alzheimer’s disease is not fully understood. […]

Science News: Nerve cells from people with autism grow unusually big and fast

Young nerve cells derived from people with autism are precocious, growing bigger and developing sooner than cells taken from people without autism, a new study shows. The results, described January 7 in Nature Neuroscience, hint that in some cases nerve cells veer off course early in brain development to ultimately cause the disorder. (January 11, […]

U.S. News & World Report: Medication-free ways to treat Parkinson’s disease

People with Parkinson’s disease, the incurable neurodegenerative disorder that affects movement, have few options for medical treatment. Prescription medications can help manage symptoms, and an implantable device (a deep brain stimulator) can help control tremors – the hallmark of the condition. But many Parkinson’s patients don’t know about additional complementary or alternative treatments that can […]

Science Blog: Decades-old question answered in Alzheimer’s brain plaques

Alzheimer’s-affected brains are riddled with so-called amyloid plaques: protein aggregates consisting mainly of amyloid-β. However, this amyloid-β is a fragment produced from a precursor protein whose normal function has remained enigmatic for decades. A team of scientists at VIB and KU Leuven led by professors Joris de Wit and Bart De Strooper has now uncovered […]

CNN: Excessive body fat around the middle linked to smaller brain, study says

Big waist, small brain? If you’re too heavy, especially around your middle, you probably have shrunken gray matter volume in your brain, according to a study published Wednesday in the journal Neurology. Gray matter contains most of your brain’s 100 billion nerve cells, while white matter is filled with nerve fibers that connect the brain […]

The New York Times: Train your brain like a memory champion

You slide the key into the door and hear a clunk as the tumblers engage. You rotate the key, twist the doorknob and walk inside. The house is familiar, but the contents foreign. At your left, there’s a map of Minnesota, dangling precariously from the wall. You’re certain it wasn’t there this morning. Below it, […]
