tDCS GROUP
CONTROL GROUP
These patients will be submitted to 2 daily sessions of cerebral stimulation, starting from the first day after the surgery, for 4 consecutive days, with each session having 20 minutes, and a minimum break of 8 hours between them. Will be applied a direct current stimulus of 2 milliampere (mA) in the right anode and in the left cathode on the prefrontal right region.
In these patients will be applied, with the same equipment used in tDCS, a simulated stimulus similar to the active one. They will also be submitted to some psychological test to evaluate theirs mnemonics, attentional, executive and global functions.
