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.

mammal brains.
