WHY EX­ER­CISE MAKES US BRAINIER

Sunday Herald Sun - Body and Soul - - NEWS -

We’ve known for years there’s a link be­tween ex­er­cise and bet­ter brain per­for­mance, but now there’s proof

that one causes the other. A study by sci­en­tists at the US National In­sti­tute on Ag­ing has shown aer­o­bic work­outs trig­ger the pro­duc­tion of new brain cells which,

in turn, boosts brain power. Dur­ing their re­search on mice, the sci­en­tists in­ves­ti­gated the ef­fect of dif­fer­ent stim­u­la­tion (play, so­cial­is­ing, ex­er­cise) on the brain and found that run­ning in a wheel caused the re­gen­er­a­tion of cells within the hip­pocam­pus (the area of the brain re­spon­si­ble for mem­ory and learn­ing)

and the mice showed im­proved cog­ni­tive per­for­mance af­ter­wards.

Pre­vi­ous brain re­search on mice has led to sim­i­lar re­sults in hu­mans.
