present study also found that PLI in the parietal delta and theta bands was significantly increased in response to rare and noise tones, compared to the standard tones. These findings suggest that presentation of the standard tone produces an evoked response characterized by higher theta and alpha/beta ERO energy, but also shows an increase in delta and theta phase variability, compared to the noise and rare tones. The relationship between brain oscillations and P3 amplitudes has not been well characterized in animal models of high and low ethanol preference. Future studies are needed in these models to determine the relationship between their genetic and phenotypic profile with the expression of their different neurophysiological endophenotypes associated with reduced P3 amplitudes.
