Dreams play a crucial role in memory consolidation by integrating recent experiences to improve short-term and long-term learning skills. The study found that subjects who dreamed about the task showed significant improvement, indicating that dreams are the brain's way of processing and understanding new information.
Researchers found that rapamycin improved learning and memory in Alzheimer's-susceptible mice, correlating with lower brain damage. The study used two different mouse models of early Alzheimer's, both showing similar results.
A study found that motor actions can determine people's emotional memories, with participants remembering more positive life experiences when moving marbles upward and more negative experiences when moving them downward. This suggests that spatial metaphors for emotion are not just in language but also in mental processes.
A computer algorithm was able to predict which film a volunteer was recalling based on their brain activity, suggesting that memories are recorded in regular patterns. The key areas involved in recording episodic memories were the hippocampus and its immediate neighbors.
Researchers at the University of Haifa have developed a handwriting-based tool that measures physical properties of handwriting to detect deception. The tool shows promise in replacing verbal-based methods such as polygraphs, providing greater accuracy and ease for law enforcement.
Scientists have found that memories are recorded in the hippocampus with a specific structure, allowing for the prediction of spatial memories. This breakthrough challenges current scientific thinking and opens up possibilities for understanding how information is processed in the brain.
Researchers at Wellcome Trust Centre for Neuroimaging discovered that brain activity can be used to predict spatial memories and locations. The study's findings challenge current scientific thinking and offer insights into how memories are encoded across neurons.

Researchers discovered that the hippocampus and entorhinal cortex are not essential for path integration, a key aspect of spatial cognition. The study used memory-impaired patients to test this theory, finding they performed similarly to controls when tracking their start location within short-term memory.

In a study by Yale University researchers, older mice benefited from either physical exercise alone or combined with mental enrichment. For younger and middle-aged mice, exercise was key to improving spatial memory. The findings suggest that cognitive stimulation can help compensate for declining memory as people age.
Treatment with Simvastatin significantly improved spatial memory in mice genetically bred to have an Alzheimer's-like disease, with more pronounced effects in males. The study found that statin increased levels of nNOS, a substance that causes dilation of blood vessels and improves circulation to the brain.

Researchers found that older male nonhuman primates' spatial memory declines at a greater rate than females, suggesting sex differences in age-related cognitive decline. The study aims to investigate factors contributing to these differences and potentially inform the development of sex-specific therapies.
Researchers discovered that brain activity in the hippocampus, a key learning center, correlates with improved memory performance after sleep. Spatial memories were found to be strengthened during slow wave sleep, suggesting that sleep plays a crucial role in consolidating recent memory traces.
A study by Yale University found that estrogen has no impact on memory in mice living in enriched environments, but improves spatial memory in those with standard conditions. The results suggest that estrogen benefits mice from un-stimulating environments more than those raised in stimulating ones.
A novel protocol distinguishes retrieval from new learning in spatial memory loss, with rats showing improved recall of original platform location despite partial hippocampal damage. This finding suggests that at least part of amnesia associated with hippocampal damage is a failure of retrieval.
