Hyperpolarization‑activated and cyclic nucleotide‑gated (HCN) channels are well expressed in the vertebrate retina. Their role in formation of electroretinographic (ERG) responses to stimulus onset (b‑wave) and stimulus offset (d‑wave) are largely unknown. In this study we investigated the effects of pharmacological blockade of HCN channels (with ZD7288 or ivabradine) on the ERG b‑ and d‑waves in...
The effects of dopamine D2‑class receptor blockade by sulpiride on the electroretinographic (ERG) b‑wave (ON response) and d‑wave (OFF response) were investigated in light‑adapted turtle (Trachemys scripta elegans) and frog (Rana ridibunda) eyecups. For turtle ERG, sulpiride (240 μM) produced an amplitude increase of the b‑ and d‑waves, while the 40 μM and 120 μM of sulpiride were ineffective. Alternatively,...
Functional interactions between serotoninergic and GABAergic systems in the vertebrate retina are largely unknown. In this study, the effects of isolated or combined stimulation of the serotonin receptors (with 100 µM serotonin) and ionotropic GABAA and GABAC receptors (with 5 mM TACA) on the electroretinographic (ERG) ON (b‑wave) and OFF (d‑wave) responses were investigated in frog eyecup preparations...
