Abstract
NOVOA, Rubén F.; CERESSA, Ivana B.; OLIVA, Maribel A. and PAEZ, Paolo D.. Correlation between emotional state and functional activation with magnetic resonance imaging. Rev. argent. radiol. [online]. 2023, vol.87, n.2, pp.45-53. ISSN 1852-9992. http://dx.doi.org/10.24875/rar.22000022.
Objective:
To explore if healthy volunteers would present a correlation between their score in emotional psychological test and the activations of brain areas related to emotions measured with functional magnetic resonance imaging (fMRI).
Material and methods:
Exploratory study of a prospective diagnostic test, with the individuals own design as a control, with a sample of 12 participants. Each participant was categorized with an emotional stability score derived from a psychological test and audiovisual emotional stimuli were used during fMRI acquisitions.
Results:
The sum of activation clusters measured in total number of voxels during negative stimuli in brain areas related to emotions showed a statistically significant negative correlation for our sample size with respect to the scores in the emotional test, with Spearmans rho of −0.623 and p = 0.0428.
Conclusions:
The fMRI paradigms used made it possible to quantify brain activations in response to emotional stimuli of positive and negative valence, and the results obtained open a perspective towards the possibility of using psychological tests and fMRI sequences to predict the possibility of the appearance of symptoms of psychological or psychiatric pathologies in response to triggering factors in a healthy population that present values close to the normal limit in these tests.
