Zapping between channels in the retina

Visual information is processed long before it reaches the brain. As early as in the retina, numerous types of cells are responsible for decomposing images into their diverse components, and for feeding these to the brain on several parallel channels.

Here the so-called bipolar cells play a central role, as the first retinal layer to process the output of the light-sensitive cells in the eye. Recently, Tübingen neuroscientists have studied the functional organisation of bipolar cells in detail, publishing their findings in Nature.
