Fig. 5From: Submicromolar copper (II) ions stimulate transretinal signaling in the isolated retina from wild type but not from Cav2.3-deficient miceEffect of KA-receptor antagonists on the KA-mediated increase of the ERG b-wave amplitudes from Cav2.3-competent mice. Normalized amplitudes were plotted under the conditions as indicated. KA was added in the presence of the KA-receptor antagonists. Note, only under 30 μM CNQX the amplitude increase was completely preventedBack to article page
