Title: Temporal evolutions of the first two Independent Components from the vbICA analysis

Description: Each temporal evolution of the Independent Components (ICs) starts at zero and the value corresponding to the maximum of its modulus is non-negative. The full range of variation, i.e. the difference between the maximum and minimum of the temporal function, is 1. Selecting either 2 or 4 components has negligible impact on the temporal evolutions of IC1 and IC2. IC1 accurately tracks the vertical displacement in the area of maximum vertical displacement, but may appear reversed due to scaling. IC2 remains almost constant until around 2001, after which it increases at a steady rate.
