After CTb injection into the perifornical region, retrogradely labelled neurons appeared in the ipsilateral amygdala, with labelled cells (especially seizure-activated ones) concentrated in medial subnuclei including MeA. About 56% of Fos+ neurons were CTb co-labelled in seizure rats versus about 11% in controls.

Made by an AI model reading the paper (claude-opus-5-5, extract@0.3.0); a second AI model (claude-opus-5-5) disagrees. “The 56% vs 11% co-labelling figures are for amygdala neurons overall after perifornical injection, not for MeA specifically.”
