Subcutaneous injection of formalin results in an increase in 50 kHz USVs. A, While 30 kHz USVs were unchanged, 50 kHz USVs were increased after formalin injection (n = 12 for saline, n = 9 for formalin, p < 0.05) B, Locomotor activity was similar between saline (n = 6) and formalin (n = 6) injected mice C, 50 kHz USVs presented in five minute blocks over the 120 minute test period. D, 50 kHz USVs summarized into three phases of the formalin licking response
