Synergy betwee n the frontal and parietal lobule during motor global coordination tests

Introduction: The nervous system is the master of the human body functions. It has been stated that the frontal lobe is responsible for the global and fine coordination, and might be more active than other areas of the cortex. In such a way, the present study aimed at identifying if the frontal lobe is more active than the somatossensorial area during tasks of global coordination. Materials and Methods: Braintech 3.000 was used (EMSA Medical Instruments, Brazil) for collecting the electroencephalographic signal. Results: The tests of global coordination, oculo-manual coordination were the electrode F3 (1.799±0.225mV) versus C3 (1.789±0.218mV), F4 (1.815±0.223mV) versus C4 (1.828±0.227mV), foot-eye coordination F3 (2.735±0.278mV) versus C3 (2.702±0.280mV) and F4 (2.821±0.267mV) versus C4 (2.763±0.258mV). None of the results presented any difference in the ANOVA one-way with 0.05 sensitivity. Discussion: The results showed great activity of the frontal cortex; however, there is an activation of the same magnitude in the somatossensorial area, suggesting an interregional coupling of information during tasks of global coordination.
