Fig 5. Changes in neurochemical levels in the striatum of rats that received either electrical vestibular stimulation or no stimulation treatment, normalised to the average of the initial baseline.

Glu–glutamate; Ser–serine; Gln–glutamine; Thr–threonine; Tau–taurine; Ala–alanine; DA–dopamine; DOPAC– 3,4-dihydroxyphenylacetic acid; HVA–homovanillic acid. Stim—Ipsi–samples collected on the side ipsilateral to stimulation; Stim - Contra–samples collected on the side contralateral to stimulation. Data points are represented as mean ± SEM. Only significant main treatment effects, i.e. due to stimulation alone, are shown for clarity (i.e. no interactions). ** = P ≤ 0.01; *** = P ≤ 0.005.
