Brain Can Learn Continuously and Improve Memory
Researchers
at Perelman School of Medicine at the University of Pennsylvania, USA have
identified a type of stem cell in mice that makes adult neurons continue to
provide new cells in the hippocampus for a life time. Hippocampus is the region
of the brain responsible for learning and memory. These findings may enable
neuroscientists to understand how to maintain youthful conditions for learning
and memory, and repair and regenerate parts of the brain after injury and
aging. These stem cells in the hippocampus region never stop replicating. This
capacity is called plasticity of the brain which is defined as the ability to
form new connections throughout life to compensate for injury and disease and
to adjust to response to new input from the environment.
