For binary (spike train) signals, take FFT of signal or autocorrelation of signal?

I want to characterize a binary time-series signal x (derived from neuron action potential data) in the frequency domain. Should I use the FFT of the original signal x, or the power spectrum (FFT of ...

Is there evidence of neurons corresponding to the certainty of next input prediction?

I think the levels of the hierarchically structured neocortex try to predict their next input. If so, is there a mechanism of measure of certainty in that prediction? For example a high prediction ...
