Dynamic Coding in the Retina
We have a new paper available online at Neuron on “A Retinal Circuit Generating a Dynamic Predictive Code for Oriented Features“. Sensory systems must reduce the transmission of redundant information to function efficiently. One strategy is to continuously adjust the sensitivity of neurons to suppress responses to common features of the input while enhancing responses to new ones. In this paper we image both the excitatory synaptic inputs and the outputs of retinal ganglion cells to understand how such dynamic predictive coding is implemented in the analysis of spatial patterns. The results demonstrate how a dynamic predictive code can be implemented by circuit motifs common to many parts of the brain.
