Responses of the population e with gain adjustment, and corresponding power spectra. (A) Time series of stimulus (black), normalized-shifted filter output kϕ_en(t−τ_d) (red) and residual signal (green) for $T_{en}^{low}$. (B) Power spectra of response signals obtained for ${\varphi }_{en}^{low}$. (C) Same as (A) for ${\varphi }_{en}^{alpha}$. (D) Same as (B) for ${\varphi }_{en}^{alpha}$. (E) Same as (A) for ${\varphi }_{en}^{beta}$. (F) Same as (B) for ${\varphi }_{en}^{beta}$. (G) Same as (A) for ${\Phi }_{en}^{(0)}$. (H) Same as (B) for ${\varphi }_{en}^{(0)}$. (I) Same as (A) for ${\varphi }_{en}^{(\mathrm{\text{I}})}$. (J) Same as (B) for ${\varphi }_{en}^{(\mathrm{\text{II}})}$.
