Imaging and manipulating engrams at the cellular level provides important insights into memory function. Read More
After creating a memory in a context, engram cells encoding the memory in the hippocampus become more excitable when the context is repeated a short time later, researchers report. Read More
Researchers propose a new theory of memory formation, reporting memory storage does not rely on the strengthening of connection between memory cells, but on the pattern of connections that form within the first few minutes of an event. Read More
Researchers have identified a neural circuit that is critical for memory retrieval. Read More
Long-term memories remain 'silent' for about 2 weeks before reaching a mature state, a new study reports. Read More
Using optogenetics, researchers have successfully retrieved 'missing' memories in mouse models of Alzheimer's disease. Read More
According to new research, stress induced depression may be overcome by inducing neurons which were activated during previous positive experiences. Read More
