View ArticleHow the brain encodes time and place
When you remember a particular experience, that memory has three critical elements—what, when, and where. MIT neuroscientists have now identified a brain circuit that processes the "when" and "where"...
View ArticleSleep may strengthen long-term memories in the immune system
More than a century ago, scientists demonstrated that sleep supports the retention of memories of facts and events. Later studies have shown that slow-wave sleep, often referred to as deep sleep, is...

An experiment using the popular video game Minecraft has shown that teens who drink too much may be in for some serious consequences in the not-too-distant future.
View ArticleInterneuron plasticity ensuring long-term memory formation
Understanding learning and memory processes is of fundamental importance to the study of brain function and provides valuable insights for disorders where these processes are disturbed. The current...
View ArticleHow the brain builds place memories
Tübingen neuroscientists have succeeded in activating dormant memory cells in rats. Using weak electrical impulses targeted at previously inactive cells in the hippocampus, the researchers induced the...
View ArticleGene linked to Alzheimer's disease impairs memory by disrupting brain's...
Scientists at the Gladstone Institutes have discovered how the major genetic risk factor for Alzheimer's disease causes memory impairment. A specific type of brain activity important for memory replay...
View ArticleStudy of individual neurons in flies reveals memory-related changes in gene...
Researchers at Princeton University have developed a highly sensitive and precise method to explore genes important for memory formation within single neurons of the Drosophila fly brain. With this...
View ArticleNeuroscientists decrypt the sleeping brain to reveal hidden memories
The brain connects sensory information from the environment to our subjective experiences, resulting in our perceptions, emotions, and memories. However, our brains need to disconnect—i.e., sleep—from...
View ArticleModel maps out molecular roots of learning and memory formation
A team of researchers has built a mathematical model that describes the molecular events associated with the beginning stage of learning and memory formation in the human brain.
View ArticleHoneybee memories: Another piece of the Alzheimer's puzzle?
A breakdown of memory processes in humans can lead to conditions such as Alzheimer's and dementia. By looking at the simpler brain of a honeybee, new research published in Frontiers in Molecular...
View ArticleModerate exercise improves memory dysfunction caused by type 2 diabetes
University of Tsukuba-led researchers show that moderate exercise may improve hippocampal memory dysfunction caused by type 2 diabetes and that enhanced transport of lactate to neurons may be the...
View ArticleEntorhinal cortex acts independently of the hippocampus in remembering...
Until now, the hippocampus was considered the most important brain region for forming and recalling memory, with other regions only contributing as subordinates. But a study published today in Science...
View ArticleStudy finds a novel target molecule to help prevent brain damage from...
With more than 130,000 victims nationwide, strokes are among the leading causes of death in the U.S. each year. According to the Centers for Disease Control (CDC), someone in the United States has a...
