The conducted regression strengthened the correlation measured between GABA A receptor density and gamma-band peak frequency (rho = 0.86, p = 0.0013; CI 95% = 0.73 − 0.98), whereas the correlation between the receptor density and gamma-band amplitude only showed a trend (rho = -0.56, p = 0.096; CI 95% = −0.83 −0.14).
