For example, if we are looking at 40 Hz gamma synchrony in a mammal brain (which is 40 cycles/s), and a velocity of electrical influence of approximately 1.4 m/s, we obtain xc = 10/40 = 0.035 meters per cycle for the maximum distance from the center of the PCC in that direction (as Bahramisharif et al. 2013 states, velocity figures for various kinds of wave propagation in cortex are generally still quite provisional since the science in this area is still new). Table 1 presents various energy pathway (resonance chain) velocities, frequencies and distance traveled in each cycle, organized from fastest to slowest velocity.
