Hippocampal lesions interfere with Pavlovian negative occasion setting.
Prenatal choline supplementation enhances sensitivity to the CS preexposure effect in rats. Prenatal choline deficiency causes selective degeneration of cholinergic neurons in the medial septal nucleus. Variations in maternal dietary intake of choline alter Pavlovian inhibitory learning of the offspring. Lack of dietary choline in utero affects cholinergic neurons in the medial septal nucleus.
