Iontophoretic tracer injections:

For retrograde tracing, we deposited 1% cholera toxin subunit B (CTB; List Biological Solutions) dissolved in distilled water into either the superior paraolivary nucleus (SPN) (n = 5), medial nucleus of the trapezoid body (MNTB) (n = 4), or lateral superior olive (LSO) (n = 3). One brain had tracer spread from the deposit to the SPN and MNTB, and was classified as such for quantification. In some animals…

2.2.6 Animal experiments

2.2.6.1 Immunization with MOG35-55 peptide and treatment with LPS For the induction of EAE, MOG35-55 peptide mixed with CFA was used. Mice were anaesthetized using a combination narcotic of 8 % ketamine and 4 % xylazine hydrochloride, in sterile 0.9 % NaCl. The animals were injected with 100 µl of MOG35-55 immunization paste (50 % MOG35-55 peptide, 50 % CFA), mixed and incubated at 4°C for 90 min prior to injection) subcutaneously in two different sites. Two hundred µl of pertussis toxin solution were applied intraperitoneal (i.p.), and mice were observed while recovering from narcosis.

 
Forty-eight hours after immunization with MOG35-55 immunization paste, the animals were injected with a second bolus of 200 µl pertussis toxin solution. …
