D1-dopamine-receptors

I want­ed to alert you to a very inter­est­ing find­ing pub­lished in a recent issue of Sci­ence, one of the world’s lead­ing sci­en­tif­ic journals.

The study was led by Dr. Torkel Kling­berg and his col­leagues from the Karolin­s­ka Insti­tute in Swe­den. The goal was to learn whether Work­ing Mem­o­ry Train­ing is asso­ci­at­ed with changes in brain bio­chem­istry, thus sug­gest­ing a mech­a­nism by which train­ing may lead to enhanced work­ing mem­o­ry capac­i­ty and a reduc­tion in atten­tion prob­lems. Thus, although Work­ing Mem­o­ry Train­ing has pre­vi­ous­ly shown promis­ing results as a treat­ment for work­ing mem­o­ry and atten­tion dif­fi­cul­ties, this was a basic sci­ence study rather than a treat­ment study.

The major find­ing was that increased work­ing mem­o­ry capac­i­ty fol­low­ing train­ing was asso­ci­at­ed with changes in brain bio­chem­istry. Specif­i­cal­ly, the researchers found changes in the den­si­ty and bind­ing poten­tial of cor­ti­cal D1 dopamine recep­tors in brain regions that are acti­vat­ed dur­ing work­ing mem­o­ry tasks.

Results from this study sug­gest a bio­log­i­cal basis for the improve­ment in work­ing mem­o­ry capac­i­ty and reduc­tions i [Read more…] about Work­ing Mem­o­ry Train­ing can Influ­ence Brain Biochemistry
