WebJan 1, 2014 · The spike-triggered average (STA) is a measure to relate a continuous signal and a simultaneously recorded spike train. It represents the average signal taken at the times of spike occurrences and with proper normalization is equivalent to the cross-correlation between the continuous signal and the spike train. Detailed Description WebJun 17, 2024 · Field potentials have obvious disadvantages as compared to spike recordings, such as: (i) The loss of spatial resolution, (ii) volume conduction, and (iii) the fact that synaptic potentials are a mixture of local and aerent inputs (Pesaran et al., 2024; Nunez and Srinivasan, 2006; Buzsaki and Schomburg´ , 2015; Einevoll et al., 2013; Buzsaki et … mayor of lebanon indianaWebFeb 29, 2012 · Spike-field coherence. Similar to Ray and Maunsell (2011), we computed the coherence between spike trains and field potentials.The coherence quantifies the phase consistency between the two signals in different frequency bands and depends on three power spectra: the cross-spectrum and the two auto-spectra. mayor of ledbury

"Webthen analyzed the “spike-field coherence” between the spikes of single neurons and the LFP recorded from the same electrode using Chronux MATLAB toolbox (Bokil et al., 2010). For frequency ranges between 20 and 170 Hz, we estimated spike-field coherence using a fast Fourier transform after multitapering (Mitra and Pesaran, 1999) with three ta- " - Spike field coherence

Spike field coherence

WebSpike-field coherence (SFC) was estimated using multitaper methods with ±10 Hz frequency smoothing with sliding windows of 500 ms. Since each neuronal action potential was recorded with several LFP activities from different electrodes, we chose LFP activity that had the highest Fano-factor across trials to estimate SFC. ... WebApr 8, 2015 · Spike-field coherence. We estimated coherence to test the relationship between spike firing and LFP (or sniff and LFP). Coherency is a method to estimate at each frequency ( f) the extent of amplitude covariation and matching phase relationship between two signals ( Jarvis and Mitra, 2001; Womelsdorf et al., 2006 ).
