Retina’s power supply makes vision possible

Helping provide energy required for visual processing.

Fluorescently labeled microtubules extend from the tips of the dendrites (top) into the axon and down into the giant synaptic terminal (bottom) of a single isolated goldfish retinal bipolar cell. A loop of microtubules encircles the inner plasma membrane of the terminal and anchors mitochondria. Credit: GRAFFE ET AL., 2015
