A newly identified neural network in the hippocampal formation plays a critical role in memory and object-location learning. The findings are highly relevant to learning and memory disorders, including Alzheimer's disease.
A new role for the hippocampus involving pattern separation and conjunctive representation in reinforcement learning is discussed.
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 report in a new PNAS study that direct stimulation of the amygdala can enhance memory of images a day later, if the stimulation is applied immediately after the images are viewed.
Researchers take control of rats' brains to induce the animals to behave as those new images were familiar and old images were novel, a new study reports.
