Durant la sessi\u00f3 de fMRI, els participants havien d\u2019escoltar fragments de can\u00e7ons del g\u00e8nere cl\u00e0ssic i proporcionar valors de plaer en una escala de l\u20191 al 4 a temps real. Per controlar la resposta cerebral davant d\u2019altres tipus de recompenses, els participants tamb\u00e9 havien de jugar en una tasca d\u2019apostes monet\u00e0ries en la que podien guanyar o perdre diners reals. <\/p>\n Els resultats varen mostrar que la disminuci\u00f3 de resposta plaent davant la m\u00fasica dels participants amb anhedonia musical est\u00e0 relacionada amb una reducci\u00f3 en l\u2019activitat del nucli accumbens, una estructura subcortical clau del sistema de recompensa. Per contra, l\u2019activitat d\u2019aquesta estructura es mant\u00e9 davant d\u2019altres refor\u00e7adors, com els diners guanyats en la tasca d\u2019apostes. <\/p>\n
\u201cResulta interessant considerar la import\u00e0ncia evolutiva de la connexi\u00f3 entre les \u00e0rees auditives, corticals, i el sistema m\u00e9s primitiu d\u2019avaluaci\u00f3 emocional, subcortical\u201d, comenta la investigadora. Aquesta connexi\u00f3 \u00e9s molt clara en les persones hed\u00f2niques musicals \u2013 les que gaudeixen amb la m\u00fasica – i en canvi es troba disminu\u00efda en els anhed\u00f2nics. \u201cEl lligam entre \u00e0rees assegura que la m\u00fasica sigui experimentada com quelcom molt gratificant, i alhora assegura la seva import\u00e0ncia a nivell evolutiu, fins i tot quan no sembla evident quin \u00e9s el guany biol\u00f2gic d\u2019aquesta producci\u00f3 cultural\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
