Changes in the power and coherence of the EEG theta-1 (4-6 Hz) and theta-2 (6-8 Hz) activity were studied in subjects (31 males, 18-21 years old) with different performance levels in logical tasks.

The achievement of better performance during the tests based on logical reasoning positively correlated with higher spectral power of theta-1 band potentials in the left cortical areas. The theta-1 band potential power increased during testing and compared to the previous period in the left occipital, parietal, central and temporal cortical areas.

Changes in the power and coherence of the EEG theta-1 (4-6 Hz) and theta-2 (6-8 Hz) activity were studied in subjects (31 males, 18-21 years old) with different performance levels in logical tasks.
