time in the quest and the values of the spectral power of delta, theta 
and alpha EEG rhythms. Individuals with a short decision-making time 
have had significantly higher power of delta rhythm of EEG in right (p 
= 0,033) and left (p = 0,007) occipital, right (p = 0,043) and left (p 
= 0,029) parietal, left center (p = 0.030) areas of the cortex. At the 
same time in these subjects there was a higher power of theta rhythm in 
right (p = 0,015) and left (p = 0,032) central and right frontal (p = 
0,023) and temporal (p = 0,008) cortical areas. In subjects of both 
groups during memorizing a reduction of alpha rhythm and beta-1 power 
was found in all areas of the cortex. In group 2 subjects performing 
the task theta rhythm power did not change and was significantly (p 
<0,05) lower than in Group 1 subjects in all cortical areas except the 
left temporal lobe. Thus the greatest differences between the test 
groups were observed in the power of theta rhythm in right center (p = 
0,0007), frontal (p = 0,0005) and temporal (p = 0,0018) cortical areas. 
During playback, the power of the alpha rhythm remained below 
background levels (p <0,03), being not different from the values 
observed during memorizing.

Thus, individuals with a short decision-making time were 

characterized by higher theta rhythm power in right temporal region 
during memorization, as well as increased power of theta rhythm in the 
frontal cortex when reproducing the signals sequence. The results 
indicate that both the high activity of the right temporal and frontal 
cortical areas may account for the rapid decision making for 
implementation of specific motor programs.
