Lis\u00e4ksi tutkittiin lyhyen psykologisen intervention vaikutusta n\u00e4ihin vasteisiin. Tutkimukseen osallistui 40 masentunutta ja 23 kontrollikoehenkil\u00f6\u00e4. Masentuneiden koehenkil\u00f6iden aivos\u00e4hk\u00f6k\u00e4yr\u00e4 mitattiin ennen\r\ninterventiota, sen j\u00e4lkeen sek\u00e4 seitsem\u00e4n kuukauden seurannassa. Henkil\u00f6t, jotka eiv\u00e4t kokeneet masennusta, mitattiin vain kerran. Masentuneet koehenkil\u00f6t jaettiin hy\u00f6tyneisiin ja hy\u00f6tym\u00e4tt\u00f6miin sen perusteella, miten he arvioivat mielialansa intervention j\u00e4lkeen. Kokeessa kuvaruudulle esitettiin toistuvasti neutraali kasvonilme (todenn\u00e4k\u00f6isyys 0.8), jonka korvasi ajoittain pelokas tai\r\niloinen kasvonilme (molempien todenn\u00e4k\u00f6isyys 0.1). N\u00e4in tutkittiin masennuksen vaikutusta kasvonilmeiden prosessointiin sek\u00e4 aivojen muutoksenhavaitsemismekanismiin. Analysoitavia vasteita olivat N170/P170 sek\u00e4 P230/N230. P230-vasteet kasvokuviin erosivat masentuneiden ja\r\nkontrollikoehenkil\u00f6iden v\u00e4lill\u00e4, mutta ilme tai sen yleisyys ei vaikuttanut P230-vasteisiin. Kontrollikoehenkil\u00f6ill\u00e4 huomattiin oikeanpuoleinen aivopuoliskojen aktivaation ep\u00e4symmetria, jota ei havaittu masentuneilla. Interventio ei vaikuttanut P230-vasteeseen masentuneilla, vaikkakin vaste\r\niloiseen kasvonilmeeseen suureni seurannassa. Muita eroja iloisen ja pelokkaan kasvonilmeen prosessoinnissa ei havaittu masentuneiden ja kontrollikoehenkil\u00f6iden tai hy\u00f6tyneiden ja hy\u00f6tym\u00e4tt\u00f6mien v\u00e4lill\u00e4. Ryhmien v\u00e4lisi\u00e4 eroja l\u00f6ytyi, kun tarkasteltiin neutraaliin ja emotionaaliseen (iloinen ja pelokas keskiarvostettuna) kasvonilmeeseen syntyvien vasteiden v\u00e4lisi\u00e4\r\neroja. Kontrollikoehenkil\u00f6iden ja hy\u00f6tym\u00e4tt\u00f6mien P170-vasteet olivat isompia emotionaaliseen kuin neutraaliin ilmeeseen. Hy\u00f6tyneilt\u00e4 mitatut P170-vasteet olivat samanlaiset neutraaliin ja emotionaaliseen ilmeeseen. N170- tai P170-vasteet eiv\u00e4t muuttuneet mittausten v\u00e4lill\u00e4. P230-vasteen mukaan hy\u00f6tym\u00e4tt\u00f6mien aivot erottelit neutraalin ja emotionaalisen ilmeen toisistaan,\r\ntoisin kuin hy\u00f6tyneiden ja kontrollikoehenkil\u00f6iden aivot. Hy\u00f6tym\u00e4tt\u00f6milt\u00e4 mitattu erottelu ilmeiden v\u00e4lill\u00e4 ei ollut n\u00e4kyviss\u00e4 en\u00e4\u00e4 seurannassa. Tulokset vahvistavat aiempaa tietoa, jonka mukaan masennus vaikuttaa emotionaaliseen prosessointiin ja n\u00e4kyy aivopuoliskojen aktivaation ep\u00e4symmetrian puuttumisena. Lis\u00e4tutkimusta tarvitaan selvitt\u00e4m\u00e4\u00e4n, ovatko poikkeavuudet aivotoiminnassa piirteenomaisia ominaisuuksia masentuneille vai kehittyv\u00e4tk\u00f6 ne vasta oireiden\r\npuhjettua.", "language": "", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Elisa Lylander (elmalyla) on 2010-11-01 16:47:51.810386.
