How common and energetically explainable are intrinsically active neurons?

11 October 2017 1 2K Report

Photoreceptors are intrinsically depolarized and continually releasing glutamate. There are more neurons that do something similar?

Energetically speaking this doesn't look as a clever option. How could it be understood?

Hércules Rezende Freitas

As I understand it, being able to aways process visual signaling in real time is a highly advantageous property, and even with intense energy demand, it creates the oportunity for animals to identify moving objects, receive more food cues from the environment and to quickly adapt to changes of light intensity.
