Transplanting embryonic neurons can reconstruct circuits in the brains of damaged adult mice.

Transplanted embryonic neurons can reconstruct circuits in the brains of damaged adult mice and restore their function, according to a neuroscience paper published online Tuesday in the British journal Nature.
findings have a huge incentive for the field of neural transplantation, which is seeking to repair brain damage and disease by introducing "alternative" cells.
and authority have pointed out that the brain cannot repair itself.
With the deepening of brain science research, scientists believe that the brain has the ability to repair itself, but very limited, so is studying the treatment of Parkinson's disease through nerve transplantation (alias: tremor paralysis, PD) is a sudden, slow progression of the central nervous system degenerative disease, characterized by slow movement and loss, muscle stiffness, static tremor and posture instability.
) and stroke (to faint suddenly, unconscious, accompanied by skewed mouth, language disadvantage and the appearance of a half-body as the main symptom of a class of diseases.
) and other diseases.
, although there have been promising results, there is no clear answer to how different possible replacement cells are from the natural cells that patients lose.
to answer this question, researchers Magdalena Goetz, Mark Furperner and colleagues at the University of Munich in Germany used sophisticated imaging methods to track embryonic neurons transplanted into the damaged visual cortical layer of mice.
part of the brain is located in the back of the brain and is primarily responsible for processing visual information.
experiment, transplanted cells quickly began to form protrusions, and after just four weeks, they looked very close to the classical nerve cells that are usually distributed on the upper layers of the visual cortical layer.
addition, transplanted cells are linked to host cells, receive electrical signals from other parts of the brain, and respond to visual stimuli.
