Social Cognitive Depression In Patients With Brain Hemispheres Coordinating Function Of Experimental Research

Objective: This study aimed to from the interhemispheric cooperation perspective,explores the brain function of social cognitive depressive disorders , thus validating theresearch hypothesis:" all mental disorders in patients with pathological psychology orsymptoms must have the two cerebral hemispheres not reasonable division of labor andcooperation for the neural mechanism". At the same time, also in order to clarify thepathogenesis of depressive disorders, and provide a theoretical basis for clinicaldiagnosis and treatment.Methods: using tachistoscopic visual half-field technique, 20 standard social cognitiondepressive patients and 20 normal controls were administered. In Experiment 1,constitute‘word’or‘non word’by left-right field, used to examine theinterhemispheric enhancement function; in experiment 2, the graph-word Stroop effect,then examine the cerebral hemispheres in collaboration of mutual inhibition effect.Results: in the experiment 1, compose‘word’or‘non word’by left-right field,experimental results show:The experimental group performed that the correct reaction times of‘word’were fasterthan the correct reaction times of‘non word’, and the correct rate of‘word’was lowerthan the correct rate of‘non word’; then the normal control group performance is sameas the experimental group in correct reaction times , but the correct rate between‘word’and‘non word’is not statistically significant differenceIn experiment 2, graph-word Stroop effect experiment results show:Social cognitive depressive patients and normal controls in the correct reaction timeare not differences between and within group, and the correct rate of three stimuluspresentation are not differences between the two groups ,but the results within groupare very worthy of attention: the correct rates were not significantly different betweenthree stimulus presentation in social cognition depression patients, then the normalcontrol group performance i‘sleft visual graphics’correct rate is less than‘right visualgraphics’and‘middle vision graphics’, correct rate between‘right field graphics’and‘middle vision graphics’have no difference.Conclusion: interhemispheric cooperation including interhemispheric enhancementand inhibition were decreased in the patients with social cognition depression.
