Spatial Information in Large-scale Neural Recordings

Frontiers in Computational Neuroscience, 2015
To record from a given neuron, a recording technology must be able to separate the activity of that neuron from the activity of its neighbors. Here, we develop a Fisher information based framework to determine the conditions under which this is feasible ...
