Local Field Potentials

Pascal Wallisch

Here we will examine the local field potential. We will also look at encoding and decoding by making use of frequency analysis. Finally, we will introduce Chronux, an open-source software package written in MATLAB®, which can be used to analyze neural data.

23.1 Goals of This Chapter

Thus far, we have analyzed data in the form of neural spike times, in the context of how neurons encode the state of the outside world, and in the context of how the state of the world can be decoded from neuronal spiking. Here, we will examine a different neuronal signal, the local field potential. We will look at encoding and decoding by making ...
