Brain cells can live at least twice as long as the organisms in which they reside, according to new research.    The study, published today (Feb. 25) in the journal Proceedings of the National Academy of Sciences, found that mouse neurons, or brain cells, implanted into rats can survive with the rats into old age, twice as long as the life span of the original mice.

Brain Cells Outlive Bodies

Brain cells can live at least twice as long as the organisms in which they reside, according to new research.

The brain con­tains some 100 bil­lion nerve cells called neu­rons (Fig­ure 1, to the rightsynapses) which branch out to form over one quadrillion con­nec­tions called synapses. (Fig­ure 2, to the left). The eas­i­est way trading brainto con­cep­tu­al­ize this is that there are more synapses in the human brain than there are stars in the known uni­verse. Mem­ory and learn­ing occur when the neu­rons and synapses reor­ga­nize and strengthen them­selves through repeated usage.
