From: Environment and body-brain interplay affect inhibition and decision-making
Effects of disrupted vestibular signal on inhibition performance according to computational measures. (a–c) In the classical stop-signal task, the stimulation of semicircular canals (condition Canal, in red) increases values of parameters σStop and τStop of SSRT distribution compared to condition Control (in green), as depicted by the expansion of the corresponding SSRT distribution tail. (d–f) In the sensorial stop-signal task, both the condition Canal and the condition Otolith (in blue), in which otoliths are selectively stimulated, are associated with higher values for parameters σStop and τStop of SSRT distribution, as illustrated by the slowing in the tail of their SSRT distributions. Working definition for parameters: σStop is the standard deviation of the main part (left part) of SSRT distribution; τStop is the mean of the right part (tail) of SSRT distribution. Interpretation scale: H1**** means extreme evidence for the alternative hypothesis; H0** means strong evidence for the null hypothesis.
