Which types of projections does V1 send?

Explanation:
V1 participates in both sending information forward for further processing and sending feedback to earlier processing stages. It projects feed-forward to higher visual areas (like V2 and beyond) to pass along the visual signal for more complex analysis. It also sends feedback projections back to the LGN, modulating thalamic input to V1 and shaping how input is transmitted upstream. This combination allows V1 to influence both downstream processing and upstream gain control, making it capable of dynamic modulation based on context, attention, and prediction. So, the best answer is that V1 sends both feed-forward and feedback projections.
