Figure 7. GABAergic circuits mediate OFF responses in L2 cells.

Figure 7

(A–F) Mean response of controls and experimental cells to a moving bright bar on a dark background (top) and to a dark bar on an intermediate illumination level background (bottom), for cells with RF centers within the bar. (A–C) Black – controls, TN-XXL expressed in L2 cells only. (A) Blue – application of GABAR antagonists. (B) Purple - application of the GABAAR antagonist picrotoxin. (C) Magenta - application of the GABABR antagonist CGP54626. (D–F) Knockdown of receptors in L2 cells and R1–R6 photoreceptors. Gray - controls, TN-XXL expressed in L2 cells and R1–R6 photoreceptors. (D) Red - knockdown of GABARs. (E) Brown - knockdown of GABAARs. (F) Orange - knockdown of GABABRs.
