Statistical analysis of the survival of newly generated cells by comparing cats receiving BrdU injection 3 days after UCN and perfused 3 h after (protocol 1) and those receiving BrdU at the same time but perfused 27 days after (protocol 2).

Repeated measures analysis of variance of the changes in the BrdU-immunoreactive cells after UCN. The main fixed effects providing the source of variation among animals were group (unilateral cochlear neurectomized cats infused with NaCl, Muscimol, or AraC), the survival postoperative (period 3 days versus 30 days), side (intact versus deafferented) and cochlear nucleus (AVCN: anteroventral cochlear nucleus; PVCN: posteroventral cochlear nucleus; CDN: dorsal cochlear nucleus and CGL: cochlear granular cell layer). Degree of freedom (d.f.), Scheffe test (F), and probability level (p) are reported. ^∗Indicates the significant variations between variables and/or their interactions.
