Virtual treasure hunt shows brain maps time sequence of memories
Using brain scans and virtual reality technology, researchers discover how a temporal map of memories is generated in the entorhinal cortex.... Read More...
Low-carb ‘keto’ or ‘Atkins-style’ diet may modestly improve cognition in older adults
A small scale pilot study reveals adults with mild cognitive impairment may have improved brain function and memory when they switch to a high-fat, low-carb diet.... Read More...
The secret of autobiographical memory is in assembly of cells
The size and shape of neural assemblies, and not the strength of signals processed by neurons or the order in which they fire, is the most critical element of recording episodic memory.... Read More...
Unexpectedly, big wins improve two kinds of memory
Unexpected rewards boost memories of specific events. The findings may have implications for treating memory problems associated with depression. ... Read More...
Aging gracefully: Study identifies factors for healthy memory at any age
Older adults who have higher levels of education, embark on more social activities and stay cognitively active have a slower rate of cognitive decline than those who engage in less self-maintenance and social activities. ... Read More...
Neural patterns key to understanding disorders such as PTSD discovered
Imbalanced communication between the hippocampus and amygdala may lead to the inability to distinguish between negative memories that have overlapping features. The findings could provide new treatment options for those with PTSD. ... Read More...
How technology can help prompt positive memories for people with depression
Researchers propose adapting computer technologies to help those with depression recall positive memories. Most existing technologies focused on supporting memory impairments are geared towards episodic memory recall and cognitive impairments related to neurodegenerative diseases.... Read More...
Our brains may ripple before remembering
Coupled ripples between the medial temporal lobe and temporal cortex are enhanced prior to successful memory retrieval. ... Read More...
Your brain may contain ‘time cells’ that help form long-term memories
New findings back up recent hippocampal research in rodents, providing evidence of a common hippocampal neural mechanism representing temporal information in episodic memory.... Read More...
More Than Just Memories: A New Role for the Hippocampus During Learning
A new role for the hippocampus involving pattern separation and conjunctive representation in reinforcement learning is discussed.... Read More...
Tracking the Birth of Memories
Researchers have identified three distinct stages of brain development that occur before an episodic memory can form.... Read More...
