Detection and analysis of spatiotemporal patterns in brain activity

Oscillatory filtering and velocity vector field calculation in LFPs from marmoset visual area MT during dot field stimulus.
A, Left: LFP waveforms from two nearby recording sites. Black lines indicate times at which snapshots are shown. Stimulus onset was at 0 s. Centre: Snapshots of LFPs across all recording channels at the indicated times. Right: Velocity vector field estimating the motion between the two snapshots. B, Same as A, but with waveforms filtered with Morlet wavelets to extract 8 Hz oscillations. C, Same as B, but only the amplitude of the 8 Hz oscillations. D, Same as B, but only the phase of the 8 Hz oscillations. All velocity fields have normalized average magnitude.
