However, a recent study of adult-deafened ferrets demonstrated that core auditory cortex was reorganized by the somatosensory modality. Because adult animals have matured beyond their critical period of sensory development and plasticity, it was not known if adult-deafening and early-deafening would generate the same crossmodal results. The present study used young, ototoxically-lesioned ferrets (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mi>n<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>3<\/mml:mn><\/mml:mrow><\/mml:math>) that, after maturation (avg. =\u2009173 days old), showed significant hearing deficits (avg. threshold\u2009=\u200972\u2009dB SPL). Recordings from single-units (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mrow><mml:mi>n<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>132<\/mml:mn><\/mml:mrow><\/mml:math>) in core auditory cortex showed that 72% were activated by somatosensory stimulation (compared to 1% in hearing controls). In addition, tracer injection into early hearing-impaired core auditory cortex labeled essentially the same auditory cortical and thalamic projection sources as seen for injections in the hearing controls, indicating that the functional reorganization was not the result of new or latent projections to the cortex. These data, along with similar observations from adult-deafened and adult hearing-impaired animals, support the recently proposed brainstem theory for crossmodal plasticity induced by hearing loss.<\/jats:p>","DOI":"10.1155\/2012\/601591","type":"journal-article","created":{"date-parts":[[2012,7,20]],"date-time":"2012-07-20T01:11:08Z","timestamp":1342746668000},"page":"1-13","source":"Crossref","is-referenced-by-count":48,"title":["Early Hearing-Impairment Results in Crossmodal Reorganization of Ferret Core Auditory Cortex"],"prefix":"10.1155","volume":"2012","author":[{"given":"M.
