Note:—Temp indicates temperature; R, room temperature PL infusion; I, PL cooled in a refrigerator before infusion (temperature approximately 3°C); IB, cooled PL passed through extension tubing coiled in an IB immediately prior to entering the microcatheter. This step was added to correct for any warming that occurred between the hanging bag and the microcatheter as the fluid passed via the pump.
↵a Temperatures reported are the lowest achieved spinal cord temperature, the recorded CSF temperature at the time that the lowest cord temperature was achieved, and the infusion flow rate at that same time. All temperatures are degrees Celsius. For animals in which different flow rates were attempted within a given infusion condition (R, I, or IB), low values for each flow rate within that infusion condition are reported.
