To further examine any changes associated with the contact and activity of bipolar cells, we looked at the paired PKC[alpha]/Bassoon profile which accounts for ON-rod bipolar cells and the photoreceptor synaptic ribbon, respectively.

The scientists observed significant changes in the component of the ERG that measures the response of the bipolar cells, supporting their earlier findings.
Activation of GABAc receptors increases presynaptic [Cl.sup.-] influx, hyperpolarizing bipolar cell and thereby inhibiting [Ca.sup.2+] entry via L-type [Ca.sup.2+]-channels [11,21, 38].
The cones contact both depolarizing bipolar cells (DBCs) and hyperpolarizing bipolar cells (HBCs) through sign-inverting (−) synapses (ON synapse) and sign-preserving (+) synapses (OFF synapse), respectively.
Long arrows indicate double-labeled bipolar cells with long prolongations situated parallel to smooth muscle fibers.

Previous studies showed that besides photoreceptors, Muller cells as well as depolarizing bipolar cells are also closely associated with changes in ERG b-waves [13-17].
