Blue light triggers memory and emphatic fear in mice via noninvasive approach

Researchers at the Center for Cognition and Sociality, within the Institute for Basic Science (IBS) in South Korea, have engineered an improved biological tool that controls calcium (Ca2+) levels in the brain via blue light. Published in Nature Communications, this optogenetic construct, called monster-OptoSTIM1 or monSTIM1 for short, causes a change in mice’s fear learning behavior without the need of […]

VR: Not suited to visual memory?!

Kyoko Hine, Assistant Professor at the Department of Computer Science and Engineering, Toyohashi University of Technology and a research team at Tokyo Denki University have found that virtual reality (VR) may interfere with visual memory. In recent years, there has been high expectations that VR will be used effectively not only in multimedia and entertainment, but also in educational settings. […]

Dementia and eating disorders: it is a problem of (semantic) memory

For the first time, it has been shown that deficits of semantic memory, an ability we use to recognize objects and use them correctly, are involved in specific eating disorders shared by patients suffering from dementia. This is suggested by a study conducted by the Laboratory of Professor Raffaella Rumiati of SISSA in Trieste just published in the Journal of […]

Anticipating performance can hinder memory

Anticipating your own performance at work or school may hinder your ability to remember what happened before your presentation, a study from the University of Waterloo has found. The study’s findings also suggest that the presence of an audience may be an important factor that contributes to this pre-performance memory deficit. “Performance anticipation could weaken memory because people tend to […]

Researchers study the mechanisms behind learning and long-term memory in the brain

When we first purchase a smart phone, all of our settings and applications are the same. But as time passes, everyone’s phones will change drastically as we adapt them to our own individual needs and preferences. In the same way, our memories and life experiences are loaded into our brains, making one person unique from another. Even the simplest experiences […]

AAN recommends people 65+ be screened yearly for memory problems

People with mild cognitive impairment have thinking and memory problems but usually do not know it because such problems are not severe enough to affect their daily activities. Yet mild cognitive impairment can be an early sign of Alzheimer’s disease or other forms of dementia. It can also be a symptom of sleep problems, medical illness, depression, or a side […]

Pinpointing how cells regulate long-lasting memories

The brain has a knack for safekeeping our most treasured memories, from a first kiss to a child’s birth. In a new study in mouse cells, Columbia neuroscientists have mapped some of the molecular machinery that helps the brain maintain these kinds of long-term memories. By observing the activity of nerve cells of the brain, called neurons, that were extracted […]

Perception and working memory are deeply entangled, study finds

Many people have an intuitive, though incorrect, understanding of how the brain works: Our senses perceive objectively factual data, and our higher-level thought processes interpret that data, pull some levers and shape our conclusions and behavior accordingly. But perception and thought are fundamentally linked, according to research published in Nature Human Behavior last week by Dwight Kravitz, an assistant professor […]
