Despite the ubiquity of normal age-related cognitive decline there is an absence of effective approaches for improving neurocognitive health. Fortunately, moderate intensity physical activity (PA) is a promising method for improving brain and cognitive health in late life, but its effectiveness remains a matter of continued skepticism and debate because of the absence of a Phase III clinical trial.
Training in lesion-symptom mapping for speech-language research Abstract: Researchers rely upon the lesion method to evaluate the speech-language status of stroke survivors and draw inferences about underlying brain function. This use of neuropsychology is highly valued in basic speech- language research because it can support causal inferences about brain structure/function relationships. Crucially, advances in analytic techniques and brain image computing are creating a new landscape for neuropsychological research.
Conservatives and liberals in America often demonize the other side, judging each other's values to be inferior and immoral. Rather than seeking understanding of others, people often shut out, talk over, or even spew hatred at people who do not share their own perspectives. This "empathy gap" reflects a tendency for empathy to break down in situations where people are in conflict or feel different from each other. This research tests ways to reduce this empathy gap by focusing on how people understand their own empathy.
People can recognize objects and concepts at different semantic levels, such as knowing that a pet is an animal, a dog, a German shepherd, and “Fido”. These levels can be remembered or forgotten differently. When people first learn a concept, the brain encodes the relevant information at each of these levels into memory. Each time a memory is retrieved, its underlying neural patterns are reactivated, including its multiple semantic levels. Yet, the neural representation of these levels of memories and reactivations are poorly understood.
