Fig. 2: Physostigmine effects in Bipolar Disorder and Healthy Controls during the inhibition of negative emotions.

Panel shows the effects of physostigmine on functional activation and behavioural performance during the inhibition of negative emotions. A increased activation in the right anterior cingulate cortex (BA32, T = 4.62 p < 0.001) in BD receiving physostigmine relative to placebo; and improved behavioral performance in terms of reaction times (p = 0.007); B decreased activation of the right caudate (T = 4.20 p < 0.001) in controls receiving physostigmine relative to placebo. C increased activation within the bilateral dorsal cingulate cortices (BA31, T = 4.11, p < 0.001) and improved accuracy in BD receiving physostigmine relative to placebo (p = 0.027), although still statistically lower than that of controls.
