WebSpike field coherence develops during learning. During similar neuroprosthetic skill acquisition in rodents, learning is accompanied by increased corticostriatal communication evidenced by corticostriatal coherence observed in the LFP, 11 as well as SFC between cortical neurons and striatal oscillations and vice versa. 10–12 Striatum is not a ... WebTo measure communication, we process spike-field activity in different frequency bands using the spike-field coherence. We can then resolve which neurons are coordinating their activity and in which frequencies. Papers. Uncovering the mysterious origins of local field potentials. Pesaran (2009) Neuron .
