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.
Researchers report histamines can help improve memory of objects up-to 25 days longer than normal in mice, as well as improving people's long term memory test scores. The study suggests taking histamines may help alleviate symptoms of memory disorders such as Alzheimer's and other dementias.
Researchers discover the protein nestin produced in astrocytes plays a role in inhibiting neural differentiation. The study reports nestin does not control adult neurogenesis by acting within neural stem cells, but by regulating Notch signals neural stem cells receive from astrocytes.
Researchers investigate why two people who experience the same event often have different memories of what occurred.
A new study reports sleeps help improve learning performance in predictable processes.
Researchers report a new 'anti-radiation' medication can help protect astronauts' brains from the cosmic radiation of deep space.
A new study reports researchers have successfully generated an artificial memory by injecting a sea snail with the RNA from another. Researchers say this approach could lead to new treatments to restore memory and alter traumatic memories in humans.
