Average apex-ratio mapped to the template brain. The average was taken over equally distributed sample points of a [τ min ,τ max ]=[1.8050,1.8636] for alpha2 and b [τ min ,τ max ]=[2.0095,2.0535] for theta. The step-size for sampling was Δ=0.005. The nodes with the highest apex-ratio in the theta band are found in posterior brain regions, where for alpha2 the apex-ratio is lowest
