Auditory brainstem response thresholds (sound pressure level in decibels) for α5−/−, β2−/−, and their age (8 months of age)-and genetic-matched control mice

Mouse number 4 kHz 8 kHz 12 kHz 16 kHz 24 kHz
α5+/+ 6 21.7 20 21.7 18.3 40
α5−/− 4 25 33.8 27.5 21.3 48.8
β2+/+ 6 38 47 37 35 55
β2−/− 3 >100 >100 >100 100 >100

The genetic background for α5−/− mice and their α5+/+ control is C57BL/6J. The genetic background for β2−/− mice and their β2+/+ control is on the mixed background of 129/SvEv×C57BL/6J.
