“…Since the normal cry is not restored after nutritional therapy (Donzelli et al, 1994), the altered cry characteristics have been interpreted as an enduring consequence of CNS damage. This idea is compelling since various forms of brain damage, including asphyxia (Michelsson, 1971;Michelsson, Sirviö, & Wasz-Hockert, 1977a), bacterial meningitis (Michelsson, Sirviö, & Wasz-Hockert, 1977b), Down syndrome (Fisichelli & Karelitz, 1963;Karelitz & Fisichelli, 1962), and congenital hypothyroidism (Michelsson & Sirviö, 1976) have been found to produce differences in the cries of the infant.…”

The male offspring of rats provided with a protein deficient diet (6% casein) for 5 weeks prior to mating and throughout pregnancy were subjected to a brief period of isolation and cooling at postnatal Days (P)7, 9, and 11, and their ultrasonic vocalizations were compared with those of well-nourished pups. Calls were categorized into 12 different types based upon their sonographic patterns. Although call rates were equal, the call characteristics of the prenatally malnourished pups differed significantly from those of well-nourished controls. At P7, their mean peak sound frequency (irrespective of call type) was significantly higher, and constant frequency calls were of both higher frequency and longer duration. Over the age range studied, prenatally malnourished pups emitted a smaller variety of calls, with significantly fewer ascending frequency vocalizations while producing either significantly fewer (P9) or greater (P11) descending frequency calls. Altered crying patterns have been related to brain damage in human babies, with more abnormal cries being associated with more severe neurological impairment. Therefore, the present results most likely reflect altered central nervous system development and function. Ultrasonic vocalization characteristics in rat pups may provide a useful early marker of the severity of disturbance to the development of the central nervous system following an insult, and offer the potential for predicting the degree of functional and behavioral deficits later in life.

“…The general time features were partly inspired by the Finnish work, but mainly by comparable measurements from studies by the American team headed by Karelitz and Fisichelli (Fisichelli & Karelitz, 1963, 1969Fisichelli el al., 1966). The individual time features, on the contrary, were mainly drawn from the Finnish work, lead by Wasz-Hockert and Michelsson (Sirvio and Michelsson, 1976;Michelsson, 1980;Thoden & Koivisto, 1980).…”

This contribution is the second part of a research project attempting to provide a tentative basis for the standardization of the terminology and methodology for the acoustic analysis of induced pain cries. The first part of the study (Raes & Dehaen, 1988) described the vocabulary and the techniques for the objective and uniform segmentation of pain cry series represented on acoustic registrations. The present paper provides a detailed description of the terms and methods necessary for the accurate and uniform durational analysis of pain cry series segmented according to these basic principles. The durational measuring system comprises eight characteristics: reaction time, total crying time, total phonation time, latency, duration, phonation time, pause and continuity. Comparatively applied to a collection of pain cry series from healthy babies and one from abnormal infants, the system proved to have a very considerable capacity to differentiate between normality and abnormality.

“…According to different authors, the latency period is from 0.6 to 3.6 sec (5,15,37). This can be accounted for partly by measuring techniques, partly by the infant's wakefulness but it is also due to the fact that the latency period is not quite uniform in healthy neonates.…”
