Response of the acoustic startle reflex (ASR) of the 2- and 6-month-old mice elicited by narrowband noise centered at 8, 12, and 20 kHz. (a) A raw startle response recorded from a mouse. (b–d) The startle amplitudes in the 6-month-old mice were significantly larger than those of the 2-month-old mice at 70–80 dB SPL (Student’s -test, ). At high intensities (90–100 dB SPL), the ASR amplitude was similar in the two groups (Student’s -test, ).
