More on the same theme.

Although still in its early days, with testing being done on rats, a paper by Bergquist [1] is very interesting. The diagrams are superb.

"Low extracellular dopamine levels produce insufficent neural noise – this
impairs signal transmission/system function.
Adding moderate noise to a low noise system will improve neural functions, if it is not optimal to begin with."

"Stochastic vestibular stimulation
• Non invasive.
• Low amplitude (<1 mA) currents selectively activates vestibular
afferents.
• By using a noisy stimulation pattern, the vestibular system is
activated without inducing the sensation of movement (vertigo)."
