Detection and analysis of spatiotemporal patterns in brain activity

Tracking pattern evolution dynamics.
A, Snapshots of 6 Hz phase and phase velocity fields from marmoset area MT LFPs during dot field stimulus, showing evolution from a plane wave pattern to a sink pattern. Black dot marks stable node location. B, Mean percentage difference between number of observed and expected pattern transitions (within 50 ms) for recording shown in A. Rows give initial pattern, columns give following pattern. Bold values indicate significant differences between observed and expected counts across all trials (p<0.05, paired t-test with Bonferroni correction). PW, plane wave; SY, synchrony; SI, sink; SO, source; SA, saddle. Node and focus critical points are combined.
