Lfp coherence
Web11. apr 2024. · Introduction. Neural coherence characterizes neural population dynamics by measuring correlations between the timing of spikes emitted by a neuron, and the fluctuations of populations as measured by local field potential (LFP) activity, as well as correlations in the timing of LFP activity at different sites, and correlations in spike timing … Web30. nov 2015. · Spike-LFP coherence analysis. Spike-LFP coherence reflects phase synchronization. First, discrete and continuous Fourier transformations were used to analyze spikes and LFP, respectively; secondly, we calculated spike spectrum S1, LFP spectrum S2, and the cross-spectrum S12; third, the numerical calculation value …

Web01. nov 2024. · Background: Local field potentials (LFP) reflect the integrated electrophysiological activity of large neuron populations and may thus reflect the … WebNeural coherence is believed to reflect neural excitability, whereby spiking tends to occur at a particular phase of LFP activity, but the mechanisms of multiregional dual coherence remain unknown. Here, we investigate dual coherence in the PPC of non-human primates performing eye-hand movements.
Web( A ) Example of LFP--LFP, MUA--MUA, and LFP--MUA coherence measures for the grating (green) and plaid (red) stimuli derived from the same pair of recording sites (Monkey 3). Thin lines correspond ... WebHpc LFP is most marked in the theta range (Figures 1B and 1C). Moreover, the time courses of coherence of prefrontal LFP and spike trains with hippocampal LFP show peak correlations in the theta frequency range, both for single prefrontal units (Figures 1B and 1C) and when all theta-modulated cells in a session are considered (Figures S1E and S1F).
Web17. jun 2024. · We also found coherence between the two 7B electrode grids (Figure 1F,H). Thus, synaptic and spiking activity in area 7B showed clear beta-band synchronization. … Web01. mar 2004. · The perception-related modulations of LFP coherence found in the present study occurred in the low- and medium-frequency ranges. Coherence at low frequencies (theta/alpha: 4–12 Hz) has recently been discussed in terms of long-range integrative processes (Schanze and Eckhorn, 1997; von Stein and Sarnthein, 2000).
Web12. apr 2024. · The phase difference between θ LFP and θ Vm was not uniformly distributed, and the θ Vm of the cells medial to the LFP recording sites preceded the θ LFP by 74° on average (Fig. 3j, P = 8.1 ...
