The bipolar cells driving parasol and midget ganglion cells in the primate retina.
(A) The large parasol ganglion cells integrate inputs across many bipolar cells (left), while the small midget ganglion cells are driven by only one or few bipolar cells. Puthussery et al. [1] now show that the bipolar cells supplying parasol ganglion cells, but not those supplying midget ganglion cells, can generate fast spikes. (B) Spikes in the bipolar cells supplying parasol ganglion cells are made possible through voltage-gated sodium channels expressed specifically at a particular axon segment (marked red) — perhaps to allow both dendritic and axonal synaptic input to impart control over the cell’s spike pattern.
