Figure 4.
Ultrasonic vocalization was not altered between SIK1-WT and SIK1-MT mice. (A) Representative sonograms recorded from isolated mice (P14) were shown. (B) Both wild-type and mutant mice made a variety of vocalizations during the isolation from their mom. (C) The number of calls was not altered during the developmental stages we examined (no statistical significance was detected by t-test). Eight SIK1-WT and seven SIK1-MT mice were analyzed. Statistical analysis was made by Student's t-test.
