Cognitive Training (Cogmed) Changes the Brain More Than We Thought

Cog­ni­tive Train­ing Can Alter Bio­chem­istry Of The Brain (Sci­ence Daily)

- “Researchers at the Swedish med­ical uni­ver­si­ty Karolin­s­ka Insti­tute have shown for the first time that the active train­ing of the work­ing mem­o­ry brings about vis­i­ble changes in the num­ber of dopamine recep­tors in the human brain.”

- ““Brain bio­chem­istry does­n’t just under­pin our men­tal activ­i­ty; our men­tal activ­i­ty and think­ing process can also affect the bio­chem­istry,” says Pro­fes­sor Torkel Kling­berg, who led the study.”

- “Changes in the num­ber of dopamine recep­tors in a per­son does­n’t give us the key to poor mem­o­ry,” says Pro­fes­sor Lars Farde, one of the researchers who took part in the study. “We also have to ask if the dif­fer­ences could have been caused by a lack of mem­o­ry train­ing or oth­er envi­ron­men­tal fac­tors. Maybe we’ll be able to find new, more effec­tive treat­ments that com­bine med­ica­tion and cog­ni­tive train­ing, in which case we’re in extreme­ly inter­est­ing territory.”

Com­ment:  could­n’t agree more with “Maybe we’ll be able to find new, more effec­tive treat­ments that com­bine med­ica­tion and cog­ni­tive train­ing, in which case we’re in extreme­ly inter­est­ing ter­ri­to­ry.” This study adds a very impor­tant angle to the grow­ing lit­er­a­ture on work­ing mem­o­ry train­ing, show­ing a more fun­da­men­tal, struc­tur­al impact, that once thought (such as the well-known effect that “cells that fire togeth­er wire togeth­er”). The com­put­er­ized cog­ni­tive pro­gram used in the study was Cogmed work­ing mem­o­ry training.
