Business Standard - - ECONOMY - PRESS TRUST OF IN­DIA

Sci­en­tists have iden­ti­fied a com­mon pat­tern of brain ac­tiv­ity be­hind bad mood, an ad­vance that could help de­velop new ther­a­pies for de­pres­sion and anx­i­ety.

Most hu­man brain re­search on mood dis­or­ders has re­lied on stud­ies in which par­tic­i­pants lie in an fMRI scan­ner and look at up­set­ting im­ages or lis­ten to sad sto­ries.

Th­ese stud­ies have helped sci­en­tists iden­tify brain ar­eas as­so­ci­ated with emo­tion in healthy and de­pressed in­di­vid­u­als, but they do not re­veal much about the nat­u­ral mood fluc­tu­a­tions that peo­ple ex­pe­ri­ence over the course of a day or pro­vide in­sight into the ac­tual mech­a­nisms of brain ac­tiv­ity un­der­ly­ing mood.

Re­searchers iden­ti­fied a com­mon pat­tern of brain ac­tiv­ity that may be be­hind feel­ings of low mood, par­tic­u­larly in peo­ple who tend to­wards anx­i­ety.
