Graphs showing number of c-Fos immunoreactive neuronal nuclei in the IC after sound stimulation at different times after lesions of the auditory cortex. (A) The number of c-Fos immunoreactive neuronal nuclei significantly drops at 1 day (42%) and 15 days (55%) after the cortical lesion. Ninety and 180 days post-lesion, the number of immunoreactive neurons following sound stimulation recovers, but still remains below control values (33% at 90 days and 23% at 180 days). *Asterisks denote the significant differences between the control groups and the stimulated control and each lesioned group, and means the average value ± 2SD (error bars). (B) The number of c-Fos immunoreactive neurons differs between the sides ipsi- and contralateral to the cortical lesion. At 1 day after the lesion, the number of c-Fos immunoreactive neurons is significantly lower in the ipsilateral side. At 15, 90, and 180 days the number of immunoreactive neurons is comparable, although slightly lower in the ipsilateral side.
