Modulation of calcium currents by electrical activity.

abstract：:1. The synaptic inputs to sustained OFF-center ganglion cells of the mudpuppy retina were studied using a superfused retina-eye-cup preparation. Intra- and extracellular electrophysiological recording techniques were carried out during bath application of 2-amino-4-phosphonobutyrate (APB), a glutamate analog that sele...
