Hu­mans make neu­rons through­out their lives

The Guardian Weekly - - Discovery -

Hu­mans con­tinue to pro­duce new neu­rons in a part of their brain in­volved in learn­ing, mem­ory and emo­tion through­out adult­hood, sci­en­tists have re­vealed. The find­ings could help in de­vel­op­ing treat­ments for neu­ro­log­i­cal con­di­tions such as de­men­tia. A re­cent study had claimed that new neu­rons in the hip­pocam­pus were at un­de­tectable lev­els by our late teens. But an­other group of sci­en­tists has re­vealed the new neu­rons are pro­duced in this brain re­gion in hu­man adults. “The ex­cit­ing part is that the neu­rons are there through­out a life­time,” said Dr Maura Boldrini from Columbia Univer­sity in New York and first au­thor of the study pub­lished in the jour­nal Cell Stem Cell.
