Behavioral Responses of Cows to Auditory Training

Opioid peptides and behavioral and physiological responses of dairy cows to social isolation in unfamiliar surroundings.

To test whether endogenous opioid peptides are involved in the behavioral and physiological responses of cattle to stress, 12 Holstein cows were either placed in social isolation in unfamiliar surroundings for 15 min or remained in their home stalls, either with or without naloxone treatment, following a Latin square design. Vocalizations (judged as high or low frequency), defecation/urination,...

AUDITORY BRAINSTEM RESPONSES (ABR) IN HYPERBILIRUBINEMIC NEWBORNS

To evaluate the changes of ABR values in hyperbilirubinemic newborns, 85 cases with severe jaundice (total bilirubin levels over 16 mg/dL and direct bilirubin less than 2 mg/dL) were selected from those admitted to Children's Medical Center by simple sampling method. These infants had no other problem except jaundice. ABR was taken before treatment in all cases and in some (10 cases) after...

Psychophysiological responses to auditory change.

A comprehensive characterization of autonomic and somatic responding within the auditory domain is currently lacking. We studied whether simple types of auditory change that occur frequently during music listening could elicit measurable changes in heart rate, skin conductance, respiration rate, and facial motor activity. Participants heard a rhythmically isochronous sequence consisting of a re...

Emotional responses to auditory stimuli

Concurrently recorded auditory event-related potentials and behavioral responses to dichotic CV stimuli.

Auditory event-related potentials (AERPs) were recorded concurrently with behavioral responses to dichotic CVs in 16 young, normal, right-handed, female subjects. The results showed the expected behavioral right-ear advantage and an N105-P184 complex of significantly greater amplitude over the left temporal region than over the right. In another normal individual showing a consistent behavioral...
