Psychostimulants Hinder Sleep And Memory With Little Benefit

Taking nonprescribed psychostimulants may slightly improve a person’s short-term focus but impede sleep and mental functions that rely on it — such as working memory. The use of prescription stimulants by those without medically diagnosed conditions marks a growing trend among young adults — particularly college students seeking a brain boost. “Healthy individuals who use […]

Pyramidal Cell Subclasses Differ By Electrophysiology And Connectivity

Efforts to parse the cellular, molecular, and behavioral components of spatial recognition are paying off with new insight into the neuroscience of memory-guided navigation. At the Janelia Research Campus, postdoctoral research scientist Mark Cembrowski, who is part of Group Leader Nelson Spruston‘s lab, has as his primary research target the subiculum. This is a sub-region […]

Dual N-back Cognitive Training Improves Working Memory

Dual n-back training, one of the two methods most scientists use in cognitive training research, is significantly better in improving memory and attention, researchers at Johns Hopkins University have found. It also results in more significant changes in brain activity. The exercise didn’t make anyone smarter, but it did greatly improve skills people need to […]

How Learning Processes Are Affected By Our Cultural Activities

Cultural activities, such as the use of language, influence our learning processes, affecting our ability to collect different kinds of data, make connections between them, and infer a desirable mode of behavior from them, a new study from Tel Aviv University suggests. Professor Arnon Lotem, of TAU’s Department of Zoology, who led the research for […]

Higher Working Memory Capacity Leads To Faster Satiation Rate

People who use more working memory capacity get tired of things faster, new research from the University of Kansas has found. Lead author Noelle Nelson, a KU School of Business marketing and consumer behavior researcher, explains: “People with larger working memory capacities actually encode information more deeply. They remember more details about the things they’ve […]
