(A,B) Stereological quantification of ChAT-positive or NeuN-positive neurons in the pedunculopontine nucleus (PPN) of control and ChAT-CKO mice (ChAT; t(14)=4.531, p=0.0005. NeuN; t(14)=0.095, p=0.92). (C,D) Stereological quantification of ChAT-positive or NeuN-positive neurons in the laterdorsal tegmental nucleus (LDT) of control and ChAT-CKO mice (ChAT; t(14)=3.571, p=0.003. NeuN; t(14)=1.934, p=0.073). (E,F) Quantification of the number of ChAT-positive neurons in the cervical spinal cord of control and ChAT-CKO mice (t(6)=3.654, p=0.0107). Scale bars = 100 μm.
