The Impact of Trait and Mathematical Anxiety on Oscillatory Brain Activityduring Lexical and Numerical Error-Recognition TasksAuthors : Alexander N. Savostyanov, Tatyana A. Dolgorukova, Elena A. Esipenko, Mikhail S. Zaleshin, Margherita Malanchini,Anna V. Budakova, Alexander E. Saprygin, Yulia V. KovasAbstract  :  The  present  study  compared  spectral-power  indexes  and  cortical  topography  of  brain  activity  in  a  samplecharacterized by  different  levels  of  trait  and mathematical  anxiety.  52 healthy  Russian-speakers  (age 17-32;  30 males)participated in the study. Participants solved an error recognition task under 3 conditions: A lexical condition (simple sentencesin Russian), and two numerical conditions (simple arithmetic and complicated algebraic problems). Trait and mathematicalanxiety were measured using self-repot questionnaires. EEG activity was recorded simultaneously during task execution.Event-related spectral  perturbations (ERSP) were used to analyze spectral-power changes in brain activity.  Additionally,sLORETA was applied in order to localize the sources of brain activity. When exploring EEG activity recorded after tasks onsetduring lexical conditions, sLORETA revealed increased activation in frontal and left temporal cortical areas, mainly in thealpha/beta frequency ranges. When examining the EEG activity recorded after task onset during arithmetic and algebraicconditions,  additional  activation in  delta/theta  band in  the right  parietal  cortex  was observed.  The ERSP plots  reveledalpha/beta desynchronizations within a 500-3000 ms interval after task onset and slow-wave synchronization within an intervalof 150-350 ms. Amplitudes of these intervals reflected the accuracy of error recognition, and were differently associated withthe three (lexical, arithmetic and algebraic) conditions. The level of trait anxiety was positively correlated with the amplitude ofalpha/beta  desynchronization.  The  level  of  mathematical  anxiety  was  negatively  correlated  with  the  amplitude  of  thetasynchronization and of alpha/beta desynchronization. Overall, trait anxiety was related with an increase in brain activationduring task execution, whereas mathematical anxiety was associated with increased inhibitory-related activity.
