The dentate gyrus (DG) is a region of the mammalian brain known to support the encoding of new memories. This brain region is part of the hippocampal formation, a set of brain regions involved in vital memory functions.
As human beings age, the functioning of organs gradually deteriorates. While countless past studies have investigated the effects of aging on the human body, brain and on cognition, the neural mechanisms and environmental ...
(Medical Xpress)—The brain's two hippocampal formations – one in each hemisphere's temporal lobe, medial to the inferior horn of the lateral ventricle and typically referring to the dentate gyrus, the hippocampus proper ...
One of the liveliest debates in neuroscience over the past half century surrounds whether the human brain renews itself by producing new neurons throughout life, and whether it may be possible to rejuvenate the brain by boosting ...

(Medical Xpress)—A team of researchers working at the University of Toronto in Canada may have found the answer to the question of why we humans tend to have little to no memory of the first few years of our lives. In their ...
(Medical Xpress)—The smooth operation of the brain requires a certain robustness to fluctuations in its home within the body. At the same time, its extraordinary power derives from an activity structure poised at criticality. ...
Neuron transplants have repaired brain circuitry and substantially normalized function in mice with a brain disorder, an advance indicating that key areas of the mammalian brain are more reparable than was widely believed.
