AI Customer ServiceProvided by the Springer Nature SharedIt content-sharing initiative Policies and ethics Bipolar cells make direct synaptic contact with photoreceptors and form a ‘through’ pathway for information transmission in the retina before this is relayed to the higher visual centers of the brain.
The most direct pathway from photoreceptors to ganglion cells is through retinal bipolar cells. Thus, it is of great interest to understand how bipolar cells transform visual signals. Werblin and Dowling (1) were among the first to investigate light-evoked responses of retinal bipolar cells.
The process of splitting images into multiple components tuned to selective visual features begins with differentiation of different photoreceptor types but is then greatly elaborated at the synapses between photoreceptors and bipolar cells.
Figure 1: Organization of the bipolar cells in a mammalian retina. a | The retina is organized in three nuclear and two synaptic ('plexiform') layers. Light entering the eye passes the entire tissue to reach the light-sensitive outer segments of the rod and cone photoreceptors, where it is transduced into an electrical signal.
Bipolar cells and their cellular partners. Tartuferi 8, a student of Golgi, has been ascribed to have coined the term 'bipolar cell' for those retinal interneurons that possess two protrusions, one going 'up' and one going 'down'. This distinct morphology is an indicator of their function, as bipolar cells link the outer and the inner retina.
In this Review, Euler and colleagues explore the features of retinal bipolar cells and examine how they shape the visual signal. Retinal bipolar cells are the first 'projection neurons' of the vertebrate visual system — all of the information needed for vision is relayed by this intraretinal connection.
