Notes

Total Power (TP)

Predictive power of given input

T P = \sum_{t = 0}^{M - 1} ∣ k (t) ∣

Excitatory Index (EI)

Inhibitory/Excitatory connections

E I = \frac{\sum_{t = 0}^{M - 1} ∣ k_{p} (t) ∣}{T P}

k_{p} (t) = {\begin{matrix} k (t) when k (t) > 0 \\ 0 otherwise \end{matrix}}

Band Power (BP)

Power in frequency band between [a,b]Hz

B P = \frac{\sum_{f \in [a, b] Hz} K (f)}{\sum K (f)}

K(f) = DFT[k(t)]
