Influence of training on the construction of evoked potentials

In the present work, a study of evoked potentials on the EEG of the human brain is carried out to compare people after training and at the first test. The test was a demonstration to the subject of an ambiguous object, in this case a Necker cube with different intensities of the sides. The subject had to evaluate the orientation of the cube and press the appropriate button: left or right. The purpose of this work is to determine how evoked potentials change when people are trained for this test. The group of subjects consisted of 21 people of different ages and genders. 11 of them have already passed the test with a similar design. The remaining 10 people faced such a test for the first time. For all subjects, evoked potentials were constructed for all EEG channels and the differences between these groups were shown.
