GAD+, c-Fos+, and GAD+/c-Fos+ cell counts (cells/field) at 63× magnification in the dLGN after visual stimulation and intravitral drug injection.

Treatment	Rat	Slices	cFos+ Cells	GAD+ Cells	GAD−/cFos+ Cells	cFos+ per Field	GAD+ per Field	GAD+/cFos+ per Field
4-AP	3	8	351	123	79	7.313	2.563	1.646

Table reports cells counts (cells/field) of GAD positive (column 3), c-Fos positive (column 4), and double GAD/c-Fos positive cells (column 5) in the dLGN following visual stimulation and intravitreal drug injection. All cells were identified at 63× magnification to allow precise detection of GAD positive cells. Highly c-Fos expressing cells (refer to text for selection threshold) were identified as c-Fos positive cells. The last three columns represent the same counts normalized by the number of fields analyzed in each condition. The first column report the number of animal tested in each condition, the second column reports the total number of slices analyzed per condition (multiple fields were analyzed for each slice).
