Relation between light responses and dendritic branching in the salamander ganglion cells.
Ganglion cells in larval tiger salamander retina were differentiated into different types according to their light response and morphology. Sustained hyperpolarizing responses were recorded from ganglion cells branching in the sclerad half of the inner plexiform layer (IPL). Sustained depolarizing responses were elicited in cells with dendrites confined in the vitread portion of the IPL. Transient responses were associated with two types of morphological units sharing level of branching, in the middle of the IPL, but differing for soma location (inner plexiform or inner nuclear layer).
