comment What is the electrical frequency range of the spinal column?
Yes, you can excite the axon bundles via external electrical stimulation. It will create action potentials (deformed ones) to travel along the nerves. Do you want to know the spectral properties of individual action potentials? Or the maximum rate of action potential generation (which is around 1kHz depending on which neuron it is)?

comment What is the electrical frequency range of the spinal column?
I think you might have a misconception about the signals in the spinal cord. They are not electric wires, and the signals are transmitted via a sequence of stereotypical pulses called action potentials. The spectral power of action potentials are somewhere over 1kHz, but that's probably not what you want to know, or is it?

comment Is tactile perception two-dimensional or three-dimensional?
@Anixx en.wikipedia.org/wiki/Vertical_sound_localization combined with other cues, not perfectly, but possible.

@Anixx but you can. Head transfer function and prior knowledge. It's mathematically possible, although not always the case.

comment What is the energy consumption of the brain?
The cortical activity pattern is measurably different between rest and sleep states. I think there would be measurable differences.

One ref for the breakdown of energy costs: Laughlin, S. (2001). Energy as a constraint on the coding and processing of sensory information. Current Opinion in Neurobiology, 11(4):475-480.

Try maximally exhaling, and then hold your breath. ;)
