Fear memories are formed when cells in the hippocampus form discrete clusters and sleep is important to the stability of these clusters.
During memory formation, the directional coupling between the neocortex and hippocampus alters. Decreased power in brain oscillations in the neocortex preceded and predicted increased power in the hippocampus. The reverse occurs during memory retrieval.
Researchers report alcohol hijacks a conserved memory pathway in the brain and alters protein expressed in neurons, forming craving that fuel addiction.
A new study reports the brain mechanisms responsible for triggering memory are identical, whether a person is awake or asleep.
A new study questions traditional views of how memories are formed and stored in the brain. Additionally, researchers propose a new mechanism for learning.
Harvard researchers reveal neurons associated with memory formation may be far more flexible than previously believed. They report their findings point to plasticity in neural networks that help with the integration of new information.
Using optogenetics, researchers manipulated pulses of neural activity during non REM sleep that made mice either remember of forget things they had learned. This novel study demonstrated that altering sleep spindle oscillations during sleep has an impact on memory formation and retention.
Researches report memory isn't a single entity and memory formation can be enhanced by different brain states.
