INFLUENCIA DE LAS VARIACIONES CLIMÁTICAS EN LA RECARGA SUBTERRÁNEA EN LA REGIÓN COSTERA DE LA PROVINCIA DE BUENOS AIRES
a) Delta band
For delta band two-way repeated measure ANOVA (group x time) depicted a significant effect of time, significant effect of group as well as a significant interaction effect. Post-hoc test for main effect of time revealed that during-ictal/non-ictal interval had a stronger source power compared to pre- and post-ictal/non-ictal intervals. The significant source maximum for during vs. pre interval and during vs. post interval was observed in the Rectus R,L region. For the effect of group it was seen that the source power for ictal GSWDs was stronger compared to non-ictal GSWDs. The source maximum, for the significant difference between ictal vs. non-ictal group was also seen in the Rectus R. Further, post hoc tests for interaction effect depicted, that the source power transition from pre interval to during interval and from during interval to post interval is stronger for ictal GSWDs is stronger compared to the transition periods of non-ictal GSWDs. The source maximum for the significant difference of

during-pre (ictal/non-ictal) and post-during (ictal/non-ictal) was observed in the Rectus region again. Neighbouring sources were seen in the regions of Frontal superior R, Frontal Inferior orb R, Para-hippocampal R,L, Olfactory L, and Frontal medial orb R.

b) Theta Band
For theta band two-way repeated measure ANOVA, only demonstrated a significant effect of time. A significant group effect and interaction effect was not found.

Post hoc tests for the main effect of time depicted that during-ictal/non-ictal interval had a stronger source power compared to pre- and post-ictal/non-ictal intervals. The significant source maximum for during vs. pre interval and for during vs. post interval was observed in the Rectus R,L region. Whereas, neighbouring sources were found in the Frontal superior orb R, Frontal Inferior orb R, region.
c) Alpha band
Two-way repeated measure ANOVA, depicted a significant effect of time, significant effect of group and a significant interaction effect.
Post-hoc test for main effect of time revealed that during-ictal/non-ictal interval for alpha band frequency had a stronger source power compared to pre- and post-ictal/non-ictal intervals. The significant source maximum for during vs. pre interval and during vs. post interval was observed in the Rectus R,L region. The neighbouring sources were found in the regions of Frontal mid orb R, Frontal Inferior tri R, and Frontal Inferior orb R, L.For the effect of group it was seen that the source power for ictal GSWDs was stronger compared to non-ictal GSWDs. The source maximum, for the significant difference between ictal vs. non- ictal group was seen in the Rectus, with neighbouring source maximum points being in Frontal inferior orb L, Temporal pole superior L, Amygdala L, R, Caudate R, region.

Post hoc tests for interaction effect revealed that the source power transition from pre interval to during interval, and from during interval to post interval was stronger for ictal GSWDs is stronger, compared to the transition periods of non-ictal GSWDs. The source maximum for the significant difference of during-pre (ictal/non-ictal) and post-during (ictal/non-ictal) was

observed in the Rectus R,L, followed by neighbouring sources in the Frontal inferior orb L, Insula L, Temporal pole superior L, Hippocampus L, Amygdala L, Para-hippocampal L region.

150 d) Beta band
Two-way repeated measure ANOVA for beta band depicted a significant effect of time, significant effect of group and a significant interaction effect.
Post-hoc test for main effect of time revealed that during-ictal/non-ictal interval for beta band frequency had a stronger source power compared to pre- and post-ictal/non-ictal intervals. The significant source maximum for during vs. pre interval and during vs. post interval was observed in the Frontal superior medial R, region.
For the effect of group it was seen that the source power for ictal GSWDs was stronger compared to non-ictal GSWDs. The source maximum, for the significant difference between ictal vs. non-ictal group was seen in Frontal superior medial R, and Cingulum anterior R, region.
Post hoc tests for interaction effect revealed, that the source power transition from pre interval to during interval and from during interval to post interval wass stronger for ictal GSWDs is stronger compared to the transition periods of non-ictal GSWDs. The source maximum for the significant difference of during-pre (ictal/non-ictal) was in the Frontal medial orb L, R, and Cingulum anterior region. For post-during (ictal/non-ictal), the source maximum was seen in Frontal medial orb L, R region.
