Shirayama, Y; Yamamoto, A; Nishimura, T; Katayama, S; Kawahara, R (2007). "Subsequent exposure to the choline uptake enhancer MKC-231 antagonizes phencyclidine-induced behavioral deficits and reduction in septal cholinergic neurons in rats". European Neuropsychopharmacology. 17 (9): 616–26. PMID 17467960. doi:10.1016/j.euroneuro.2007.02.011.Coluracetam has been shown to reverse the loss of choline acetyltransferase production in the medial septal nucleus of rats exposed to phencyclidine (PCP), and is considered a potential therapeutic drug for schizophrenia
What would be the significance of this? Is this sort of effect of PCP chronic?
