RB–AII connections. A: Dominant connections. The ratio of the number of contacts at the dominant connection to the total number of contacts for each RB cell is shown above each column. B: Histogram of ribbon contacts from RB cells to each AII amacrine cell (12 RB cells to AII 1, 12 RB cells to AII 2, and nine RB cells to AII 3). The abscissa shows the RB cells ordered by the number of contacts they make onto AII amacrine cells. The ordinate shows the number of ribbon contacts at each connection.
