WebDec 15, 2016 · The fluctuation of field potentials (FPs) in the brain is an aspect of neural activity that is increasingly used as a reflection of the ongoing transmission through neural networks. In addition, FPs seed the electroencephalograms (EEG) that are recorded from outside the brain and thus, they have enormous clinical relevance. WebThe local field potential (LFP) is a summation signal of excitatory and inhibitory dendritic potentials from a large number of neurons in the neighborhood of the recording site. Spiking activity, in contrast, originates from a single neuron located close to the electrode tip. ...
