Fig.1. Chronic spinal cord imaging chambers.
(A) The system developed by Farrar, et al. uses machined parts, including two small metal bars and a top plate, to create a sealed chamber that is fixed to the spine. Reproduced from (Farrar et al., 2012). (B) The approach described by Fenrich, et al. relies on small bent pieces of metal and glue to create a sealed chamber that is secured to the spine. Reproduced from (Fenrich et al., 2012; Fenrich et al., 2013a). (C) Figley, et al. sealed the laminectomy separately and then secured a mounting frame to the surrounding muscle and soft tissue over the spine. Scale bar = 10 mm. Reproduced from (Figley et al., 2013).
