Genetically engineered mice suggest new model for how Alzheimer’s causes dementia

Using a novel, newly developed mouse model that mimics the development of Alzheimer’s disease in humans, researchers say they have been able to determine that a one-two punch of major biological ‘insults’ must occur in the brain to cause the dementia t…

The irony of awkward

BYU study shows the effects of problematic media on social withdrawal for young millennials.

Neuroscience of bullying: Why do some find it rewarding?

Breaking research investigates the reward circuits involved in unnecessary aggression. The findings give new insights into the origins of bullying.

Trauma induces more alcohol craving than stress among veterans with PTSD and co-occurring alcohol dependence

Post-traumatic stress disorder (PTSD) and alcohol dependence (AD) are two of the most common and debilitating disorders diagnosed among American military veterans. AD and PTSD often occur together, and this co-occurrence has a worse prognosis than eith…

Cerebrovascular disease linked to Alzheimer’s

While strokes are known to increase risk for dementia, much less is known about diseases of large and small blood vessels in the brain, separate from stroke, and how they relate to dementia. Diseased blood vessels in the brain itself, which commonly is…

The relentless dynamism of the adult brain

Scientists were able to make real-time observations over a period of several months that reveal how new adult-born neurons are formed and evolve in the olfactory bulb of mice. They made the surprising discovery that there is constant structural plastic…

A little spark for sharper sight

Stimulating the brain with a mild electrical current can temporarily sharpen vision without glasses or contacts, researchers have found.

New experimental system sheds light on how memory loss may occur

Spatial memory decays when the entorhinal cortex is not functioning properly, a new mouse model shows. The study, say the authors, provides new information about how dysfunction of this circuit may contribute to memory loss in Alzheimer’s disease.

Fast fluency: Can we identify quick language learners?

Ever wonder why some people seem to learn new languages faster? The secret might lie in the brain activity they generate while relaxing.

MRI technique induces strong, enduring visual association

Volunteers in a brain science experiment learned associations between patterns and color such that when shown the patterns later, they were still biased to perceive the color even if it wasn’t really there.
