Reduction of semantic memory could be an indicator of Alzheimer's disease 12 years before onset. Researchers examine different types of memory loss associated with dementia.
Mouse study reveals intermittent fasting improves long-term memory retention and promotes hippocampal neurogenesis. The findings could help to slow cognitive decline in older adults.
Mouse study reveals how neurons reorganize following experiencing novel stimuli. The study reports a possible mechanism for memory consolidation and recall, shedding new light on the biological underpinnings for long-term memory.
Study implicates the mps-2 gene in the formation of long-term memory.
Fruit fly study reveals suppression of a genetic switch boosts long-term memory.
A single insulin-like molecule produces in the nervous system of the marine mollusk Aplysia californica strengthens connections between neurons, enhancing long term memory.
What you eat may impact your long-term spatial memory. Rats fed a cafeteria-style diet, high in saturated fats and refined carbs, experienced deterioration in spatial memory that was incremental, according to the pattern of access to junk foods.
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.
New findings back up recent hippocampal research in rodents, providing evidence of a common hippocampal neural mechanism representing temporal information in episodic memory.
