A new study published in Psychological Science reveals that people's internal mental maps are oriented towards the north, improving accuracy in spatial tasks. The study found that participants performed best when facing north and drew differently oriented maps, but only used their memorized map as a reliable source of spatial information.
Researchers at Baylor College of Medicine developed a memory-enhancing drug by inhibiting PKR activity, which boosts excitability and enhances learning and memory. In mice, PKR inhibition led to increased synaptic activity caused by gamma interferon, mimicking the effect of a 'memory pill'.
A new study reveals that people's spatial memory biases develop as they become more familiar with a particular area. As individuals better understand the relationship between buildings on a campus, they tend to exaggerate distances and create cognitive biases.
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.
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.
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 found that physically fit elderly adults have larger hippocampi and better spatial memory than their less fit counterparts. The study suggests that exercise can influence brain structure and cognitive function, with implications for aging and independence.
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.
A double-blind study found Pycnogenol improved both numerical and spatial working memory in senior citizens. The antioxidant extract reduced oxidative stress markers, indicating a potential role in preserving or enhancing mental functions.
Research by Atsuko Kasahara and colleagues found that mitochondrial respiration deficiencies are associated with changed social behavior and elevated spatial memory in laboratory mice. The study suggests a potential link between mitochondrial breakdowns and mental illness in humans.
A new study by OHSU researchers has found that children carrying the apoE4 gene already exhibit reduced cognitive function. They used a virtual reality test to assess spatial learning and memory in 7- to 10-year-olds with and without the gene.
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 picornavirus-related infections can accumulate over an individual's lifetime, leading to clinical cognitive memory deficits. The study suggests a link between picornavirus infections and inflammation of the brain, particularly in the hippocampus region.
Research shows brain activity persists and evolves with time after learning new information, integrating recent memories through dynamic processing. The findings challenge the idea that sleep is essential for strengthening memories.
A study by Yale University researchers found that ghrelin, a hormone produced in the stomach, has a powerful influence on the hippocampus, a brain region critical for learning and memory. This discovery suggests that a potential recommendation could be to limit children's breakfast intake to optimize morning learning hours.
Researchers found that sleep-restricted rats showed reduced neurogenesis in the hippocampus after learning a spatial task. However, those who used visual and odor cues to navigate had better performance on the task, suggesting an adaptive strategy to compensate for lack of sleep.
Sandstrom aims to understand the relationship between estradiol's neuroprotective effects and its ability to preserve learning and memory abilities. His team will examine biological mechanisms and hormone interactions to uncover new insights into estrogen's role in brain function.
Researchers at Ohio State University discovered that mice brains shrink during winter, impairing spatial memory, while nonspatial learning and memory remain unaffected. The study suggests a possible link between melatonin levels and seasonal changes in brain size and function.
A new study on Rhesus monkeys found that a gender gap in spatial memory decreases with age and can be overcome with simple training. Young female monkeys showed significant improvements in spatial memory when trained, closing the gap between males and females.
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.
