Model

Each of the j electrodes is described by an ordered pair ($x_{j},y_{j},z_{j}$) in 3-dimensional space. To complete this analysis, the electrodes were first projected onto the $(x,y)$ plane, removing the depth of the head. Figure 1A shows the locations of each electrode in this 2d-space. Following this projection, the time courses for each of the 92 electrodes were Hilbert transformed and then normalized following the procedure listed using Eq. (2). A probability was defined in this electrode-position space as the square of the Hilbert transformed time course (Eq. 3), analogous to the wavefunctions of quantum mechanics. Eight regions Anterior L/R, Posterior L/R, Parietal L/R, Occipital L/R) were then defined by grouping the 92 electrodes, and the frequencies of entering each region fG were obtained by summing the probabilities electrodes within the group, then integrating in time.

$Prob_{G}(t)=\sum _{j=1}^{92}\Psi _{k}^{*}(t)\times \Psi _{k}(t);f_{G}={\tfrac {1}{T}}\sum _{j=1}^{T}Prob_{G}(t)$

where each of the eight groups denoted by the subscript have a different number of constituent electrodes N. In the occipital left and right there are 10 electrodes each, in the parietal left and right there are 17 electrodes each, in the posterior left and right there are 10 and 11 electrodes respectively, and in the anterior left and right there are 8 and 9 electrodes respectively.

Upon getting the group level frequencies average values for position and momentum were calculated using Eqs. (4) and (5) (with identical expressions for y). Finally, to ascertain our analogous uncertainty principle, we sought expressions of the form

$\bigtriangleup x={\sqrt {\langle x^{2}(t)\rangle -\langle x(t)\rangle ^{2}}};\bigtriangleup p_{x}={\sqrt {\langle p_{x}^{2}(t)\rangle -\langle p_{x}(t)\rangle ^{2}}}$
