摘要: Rat pup ultrasonic vocalizations (USV) are usually studied in outbred rats belonging to either Long-Evans, Sprague-Dawley, or Wistar stocks, but these were not compared so far. We therefore performed a stock comparison and analyzed USV of male pups (postnatal day 11) three stocks. Pups all stocks showed substantial isolation-induced USV, differed various call features, like numbers, peak frequency, frequency modulation. Also, different types identified by means quantitative approach based on modulation, it was found that their proportions between These results discussed with respect functional aspects USV.
