ab: Summary: Evoked and coordinated brain signals often exhibit distinct,
    individualized spatial and temporal characteristics, such as amplitude
    and phase couplings across and within spatial channels. In the study of
    these brain potentials, it is important to characterize both the
    spatial and temporal morphologies of the responses for a better
    understanding of both the physiology and function of the brain. This
    paper presents a method for visualizing the characteristic
    spatio-temporal brain activity associated with two distinct conditions.
    This method, called Independent Spatio-Temporal Patterns (ISTPs),
    extends Common Spatial Patterns (CSPs) for spatio-temporal pattern
    visualization by adding temporal features. Independent component
    analysis (ICA) is then applied to extract independent spatio-temporal
    patterns corresponding to each condition. The results indicate that the
    inclusion of temporal features can provide useful insight regarding the
    spatio-temporal characteristics of sensorimotor rhythms.
