Neonatal cholinergic lesion alters the acoustic structure of infant rat vocalization but not the early cognitive development.

Kruger HS, Hanganu-Opatz IL (2013) Neonatal cholinergic lesion alters the acoustic structure of infant rat vocalization but not the early cognitive development. Dev Psychobiol 55(3):294-308. doi: 10.1002/dev.21029

Summary: The architecture of the cerebral cortex is dependent on cholinergic innervations for proper maturation and network assembly. The authors administered 0.1 μg of 192-IgG-SAP (Cat. #IT-01) to each lateral ventricle of rats on the day of birth. Although the resulting cholinergic depletion did not affect the general development of the rats during the first two weeks of life, infant ultrasonic vocalization was significantly affected. The altered vocalization did not affect maternal care of the pup, suggesting that previous results recording behavioral deficits in the pups after basal forebrain lesions were due to cholinergic depletion rather than altered mother-pup interaction.
