Neuroscientists have located the cells that help reprogram long-lasting memories of traumatic experiences towards safety, a first in neuroscience. Memories of traumatic experiences can lead to mental ...

The dentate gyrus is distinct from the entorhinal cortex, the hippocampal region affected in early-stage Alzheimer's disease. Previous work, including by the laboratory of senior author Scott A. Small ...

Newborn granule cells show high excitability that disappears as the cells mature. Little has been known about the mechanisms that create low excitability in mature cells or how excitability of the ...

The dentate gyrus (DG) is the input region of the hippocampus and plays an important role in learning and memory. Although emerging evidence suggests that abnormal expression of the polycomb ...

Despite doubts last year about human adult neurogenesis, a study shows even 80-year-olds develop new cells in the hippocampus, but such growth is diminished in patients with Alzheimer’s disease. A ...
