Early Hearing-Impairment Results in Crossmodal Reorganization of Ferret Core Auditory Cortex

Table 1

Hearing and age statistics for the ferrets with early hearing loss induced by ototoxic lesion (OT); all animals were male. The age of hearing onset in ferrets is ~32 days postnatally, and auditory critical period closure for A1 is 80 days [16].

ID no.	Weight	Age at OT lesion	ABR hear threshold	Age at recording	Impairment duration	BDA volume
DJF 1	1.7 kg	49 days	65 dB SPL	148 days	99 days	0.5 μL
DJF 3	2.3 kg	49 days	65 dB SPL	182 days	133 days	0.5 μL
DJF 4	1.9 kg	49 days	85 dB SPL	190 days	141 days	0.5 μL
