Objective: this study aimed to observe the cortical interhemispheric coherence in girls in the pre and post-menarche. Materials and methods: a sample was composed of 45 girls between 10 and 15 years divided into two groups: pre-menarche (G1) and post-menarche (G2) composed of 21:24 girls, respectively. The participants of the study were submitted to the electroencephalographic signal at rest. After data collection, we performed the calculation of the dependent variable extracted from the quantitative electroencephalogram.For the analysis of interhemispheric coherence index Mann-Whitney tests were run for each pair of electrodes (front F3-F4; core: C3 -C4 and P3-P4), in particular en el beta frequency rate (13 -35 Hz). Results: there were statistically significant differences in the three cortical regions (F3-F4: p = 0.001, C3-C4: p = 0.002 and P3-P4: p = 0.003). Specifically, the post-menarche group presented significantly higher coherence values in the three pairs of electrodes analyzed, that is, in the three cortical regions when compared to the pre-menarche group. This means that the higher the degree of maturation of the group, the greater the possibilities of inter-hemispheric coherence values present higher. Conclusion: it was observed that, in relation to the electroencephalographic characteristics, the groups were different and the cerebral activity related to interhemispheric coherence of the post-menarche group was higher.
