WebApr 1, 2015 · The spike-field coherence may be carrying information on odor features such as identity or intensity that are detected from the beginning of a go–no go odor-learning session. Alternatively, spike-field coherence may not change during the behavioral session because it codes for value and reward in a mix of positive and negative coding schemes. 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.

WebSep 11, 2024 · LGN Neurons Show Increased Spike-Field Coherence with NREM Thalamocortical Oscillations During OSRP Consolidation. OSRP is expressed in V1 only after several hours of poststimulus sleep; critically, sleep deprivation following visual experience prevents OSRP consolidation ( 7, 8) ( SI Appendix, Fig. S3 ). 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 ...
