Retina bipolar GLU cell | Axon terminal | Glutamate | activate both NMDA and nonNMDA receptors of ganglion cells | Activation of the Ca2+ current by depolarization as short as 15 ms in a single bipolar cell evokes the glutamatergic postsynaptic currents, of both both NMDA and non-NMDA types, in the Ganglion cells (Matsui K et al, 19982 ). (Hartveit E, 19991 ). |
Retina bipolar GLU cell | Axon terminal | I T low threshold | . | Low-voltage-activated (LVA) and high-voltage-activated (HVA) Ca2+ currents were observed in the isolated rod bipolar cell terminal recordings(Pan ZH, 20013 ). T-type calcium current recorded in bipolar cells in slice in mouse (de la Villa P et al, 19984 ). (Hartveit E, 19991 ). |
Retina bipolar GLU cell | Axon terminal | I L high threshold | . | High-voltage-activated (HVA) and low-voltage-activated (LVA) Ca2+ currents were observed in the isolated rod bipolar cell terminal recordings(Pan ZH, 20013 ). Whole-cell patch-clamp recording of ICa from presynaptic boutons are comparable to that obtained from somatic recordings, but elevation of intracellular Ca is restricted to the presynaptic terminals, with no somatic or axonal changes observed (Protti DA and Llano I, 19985 ). L-type ICa was found only in cells that retained axon terminals ramifying in the inner plexiform layer(de la Villa P et al, 19984 ). (Hartveit E, 19991 ). |
