Looking for a more realistic way to study memory, we turned to place cells—a network of cells that record a rat’s memory of an environment. Each place cell would fire only when the rat was in one particular location in space, creating a map as the

Long-term potentiation (LTP), discovered in the 1970s, was later shown to be the molecular basis of memory. Since many diseases of aging affect memory, could memory formation and storage be altered by the same mechanisms in normal aging and diseased
Early on, researchers had learned that the hippocampus was the structure in the brain where long-term memories were created and stored, but it was not known whether the different cell types within this structure might be more or less susceptible to t

In the memory circuits of the aging brain and the signaling pathways of pain, science is trading mystery for mastery.
Researchers find antibiotic resistance genes in 30,000-year-old bacteria, suggesting such resistance is not a modern phenomenon.
A blood protein involved in allergy contributes to the decline in brain function and memory in aging mice.
Older male mice sired offspring that had more copy number mutations, including several linked to autism and schizophrenia
