Experimental design. (A) The upper left eyelid position and the EMG activity of the ipsilateral orbicularis oculi muscle were recorded. Peripheral stimuli consisted of a tone presented biaurally as a CS and air puffs presented to the ipsilateral cornea as a US. (B) Diagram of the rabbit cortex, illustrating the stimulating and injection sites. MC I, motor cortex; PMC, premotor cortex; SM I, somatosensory cortex. (C) Photomicrograph illustrating the location of the stimulating site in the right mPFC (arrow). (D) Photomicrograph illustrating labeled neurons located in the mediodorsal thalamic nucleus (MD) following BDA injection in the mPFC, as indicated in B. NH, habenular nucleus; V, ventricle.
