Figure 4.

Time frequency plots and scalp maps showing alpha (8–12 Hz) and beta (12–30 Hz) oscillations for the central cluster (C3, Cz, C4) in the pre-motor preparation period (−3,000 ms to 0 ms) for successful (Hits: blue) and unsuccessful (Misses: red) putts (n = 12). There was a significant main effect for performance for central beta power, but no other results were significant. The dashed black box highlights central beta activity with associated plot and topographic maps. The solid black line highlights central alpha activity with associated plot and topographic scalp maps.
