these results suggest that the top-down influence of a21a may alter the response adaptation of v1 neurons through activation of local inhibitory circuitry, which enhances network inhibition in the v1 area upon an increased top-down input, weakens inhibition upon a decreased top-down input, and thus maintains homeostasis of v1 neurons in response to the long-presenting visual signals. |

these phenomena reflect the feedforward-feedback-verify-and-reweight (ffvw) process for visual inference in central vision, and are consistent with the central-peripheral dichotomy that central vision has a stronger top-down feedback from higher to lower brain areas to disambiguate noisy and ambiguous inputs from v1. |
