The secret of autobiographical memory is in assembly of cells
The size and shape of neural assemblies, and not the strength of signals processed by neurons or the order in which they fire, is the most critical element of recording episodic memory.... Read More...
Unexpectedly, big wins improve two kinds of memory
Unexpected rewards boost memories of specific events. The findings may have implications for treating memory problems associated with depression. ... Read More...
What makes memories stronger? Rat Study
Hippocampal replay selectively enhances memory of highly rewarded locations in a familiar context.... Read More...
Sleep frees the hippocampus for new memory contents
A rapid memory system transition from the hippocampus to the posterior parietal cortex is stabilized as we sleep. Sleep and repeated rehearsal of memory jointly contribute to long-term memory consolidation.... Read More...
Key brain region for navigating familiar places identified
The posterior hippocampus tracks distance to a newly learned location, as well as familiar environments. By contrast, when navigating a familiar location, the retrosplenial cortex takes over responsibility for tracking distance. The findings shed light on how the brain navigates and encodes spatial information.... Read More...
Rocking Improves Sleep and Memory in Both People and Mice
A new study reveals people fall asleep faster when being rocked. Additionally, they showed improvements in memory consolidation and spent more time in non-REM sleep.... Read More...
Early Development of Memory for Space and Time
Researchers report episodic memory develops in distinct stages during postnatal maturation.... Read More...
The Eyes Have It: Prions in Eyes of Those with sCJD
Researchers have found evidence of sCJD related prions in the eyes of patients. The findings could lead to new diagnostics for the disease and help prevent transmission. ... Read More...
Brain Prioritizes Most Rewarding Experiences When Storing Memories
A new study reveals that over night, the brain automatically preserves memories for important events and filters out other, less relevant information. The findings provide new insight into the processes that help guide decision making and human behavior. ... Read More...
Nose Breathing Enhances Memory Consolidation
A new study reports you may be able to improve long term memory consolidation by simply breathing through your nose.... Read More...
Memory Brainwaves Look the Same in Sleep and Wakefulness
A new study reports the brain mechanisms responsible for triggering memory are identical, whether a person is awake or asleep.... Read More...
