Yhdess\u00e4 koeasetelmassa kaikilla seitsem\u00e4ll\u00e4 kasvonilmeelle oli yht\u00e4 suuri todenn\u00e4k\u00f6isyys esiinty\u00e4 (p=0.14). Nelj\u00e4ss\u00e4 muussa koeasetelmassa k\u00e4ytettiin niin sanottua oddball paradigmaa, jossa neutraali kasvonilme esitettiin usein (p=0.80) ja surullinen tai iloinen ilme esitettiin harvoin (p=0.20). Sama asetelma toistettiin my\u00f6s p\u00e4invastaisella \u00e4rsykej\u00e4rjestyksell\u00e4. Kasvoherkk\u00e4\u00e4 N170 vastetta analysoitiin 18 masentuneelta ja 10 ei-masentuneelta koehenkil\u00f6lt\u00e4.

Sen sijaan kun neutraalia ja iloista kasvonilmett\u00e4 esitettiin, iloinen kasvonilme sai aina aikaa suuremman amplitudin kuin neutraali kasvonilme riippumatta sen esiintymistodenn\u00e4k\u00f6isyydest\u00e4 (p= 0.20 tai p=0.80). Ei-masentuneilla koehenkil\u00f6ill\u00e4 latenssit olivat pidempi\u00e4 oikealla aivopuoliskolla kun iloinen kasvonilme esitettiin harvinaisena (p=0.20) \u00e4rsykkeen\u00e4, kun taas masentuneilla t\u00e4llaista puoli-suuseroa ei ollut havaittavissa.

Ei-masentuneilla t\u00e4llaista puolisuus eroa ei havaittu. BDI ja SCL-90 kyselylomakkeiden mukaan pystyimme ennustamaan 20\u201329% emo-tionaalisten kasvonilmeiden synnytt\u00e4mist\u00e4 ERP vasteista.

The ERPs of two groups: depressed and non-depressed were compared. Also the effect of a short psychological intervention to the ERPs was studied. Seven universal expressions were used as stimuli in five experi-ments. In one experiment all the seven universal expressions were presented with equal probability (p=0.14). The four other experiments used an oddball paradigm i.e. condition in which a neutral ex-pressions was shown as frequent (p= 0.80) and sad or happy expressions as infrequent (p=0.20) stimu-lus and vice versa were applied. The face specific N170 component was analyzed from 18 depressed and 10 non-depressed participants. The depressed participants were divided into two groups: an initial treatment group and a waitlist control group. The EEG measurement was done for both groups before the initial treatment group\u2019s therapy intervention. The second EEG recording was done after the initial treatment group finished their therapy intervention five weeks later. Results of the equal probability condition showed that ERPs of emotional expressions elicit stronger N170 amplitudes than neutral ones. In the odd-ball experiments no differences between sad and neutral expressions were found. When neutral and happy expressions were used, happy expression always elicited stronger amplitudes than neutral expressions regardless of its prevalence (frequent p=0.80, infrequent p=0.20). The non-depressed participants got longer latencies to infrequent happy expressions on the right hemisphere compared to the left but no such hemisphere discrimination was found in the depressed participants. In the frequent happy and infrequent neutral face condition N170 amplitudes of the depressed participants on the right hemisphere were found to be stronger compared to the left, no such discrimination was found among the non-depressed controls. The BDI and SCL-90 inventories predicted 20-29 % of the variation of the emotional ERPs suggesting that depression symptoms might affect the brain\u2019s emo-tional processes. However the therapy intervention was not found to affect the ERPs of the depressed participants in this small sample.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Tero M\u00e4ki (terhenma) on 2013-09-30 05:42:55.356605.
