Clinical Trial Summary

Quantitative assessment of the activation of brain areas by functional magnetic resonance imaging (fRMI) in the face of positive and negative emotional stimuli using audiovisual materials validated for the local population and its correlation with degrees of emotional disorder based on a score obtained by a validated questionnaire for the local population, in 16 volunteers from the city of La Rioja in Argentina.

Description:

The technology applied in fMRI allows us to visualize on a color scale the changes in blood flow in those sectors of the brain that increase their metabolic activity during a given action. This is achieved by mapping the cerebral blood volume, which increases or decreases according to the metabolic activity in a certain region of the brain. This indirect method of measuring the metabolic activity of brain areas is very useful for anatomically identifying motor areas and critical functions in individual patients prior to neurosurgery, to allow better surgical planning. Currently this is its main application in healthcare practice. In the field of research it is applied in clinical neurology, psychiatry and psychology. Studies have been conducted on the activations of brain regions in basic emotions. There is less data on the quantitative differences of these activations in the Argentine population according to the degree of emotional disorder, this being the object of study of this project. Emotional disorders are transversal to different pathologies, with or without a psychotic component.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Differences in fMRI brain activation response in specific brain regions in response to positive and negative emotional stimuli	A score will be assigned to each participant according to the results obtained in a validated questionnaire to categorize emotional disorder with 37 questions, each of them with a score of 0, 1 or 2 according to the answer, to give a score to each participant that will be on the scale from 0 to 74.; The stimuli consist of the projection of audiovisual material validated to generate positive or negative emotions. The activations are quantified in a 1.5 Tesla resonator and the units of measurement for each region of interest will be cm3 of activated tissue and Z-value of fMRI activation.; Once the informed consent is signed, the participant is asked to answer the questionnaire to categorize the emotional score. After this survey, the fMRI is acquired, measuring the activation by areas from the beginning of the audiovisual stimuli until their completion. The time for the fMRI acquisition session for each participant in this cross-sectional study is estimated 20-minute .
