Term: intermediate vertical fusiform cell

Definition: The intermediate vertical fusiform cells have cell bodies 12-18 micrometers in diameter in the upper portion of the zone of vertical cells and their dendritic fields extend from the collicular surface to the deep margin of the zone of vertical cells (fig. 12b, 13). Intermediate vertical fusiform cells most often have a superficial field with relatively fewer spines, straighter, more even caliber dendrites that branch less often but more equally than those in the deep field of the same cell (figs. 12b, 13).
