Gamma-frequency firing persistently enhances intrinsic excitability in retinal ganglion cells
Experience-dependent plasticity is usually attributed to synaptic changes, but neuronal output also depends on changes in intrinsic excitability. Whether intrinsic excitability is persistently modified at the retinal output stage is unknown. Using whole-cell recordings from retinal ganglion cells (RGCs) of juvenile rats, we found that 40-Hz firing produced sustained potentiation of intrinsic…
