Differential developmental changes in cortical representations of auditory-vocal stimuli in songbirds.

J Neurophysiol 2018 Dec 12. Epub 2018 Dec 12.

University of Southern California, United States.

Procedural skill learning requires iterative comparisons between feedback of self-generated motor output and a goal sensorimotor pattern. In juvenile songbirds, neural representations of both self-generated behaviors (each bird's own immature song) and the goal motor pattern (each bird's adult tutor song) are essential for vocal learning, yet little is known about how these behaviorally relevant stimuli are encoded. We made extracellular recordings during song playback in anesthetized juvenile and adult zebra finches ( Taeniopygia guttata) in adjacent cortical regions RA (robust nucleus of the arcopallium), AId (dorsal intermediate arcopallium), and RA-cup, each of which is well-situated to integrate auditory-vocal information: RA is a motor cortical region that drives vocal output, AId is an adjoining cortical region whose projections converge with basal ganglia loops for song learning in the dorsal thalamus, and RA-cup surrounds RA and receives inputs from primary and secondary auditory cortex.

Sclerosis of the arytenoid cartilage and glottic carcinoma: A clinical-pathological study.

Head Neck 2018 Dec 7. Epub 2018 Dec 7.

Otolaryngology Unit, Vittorio Veneto Hospital, Treviso, Italy.

Background: Given the relevance of any tumor invasion of the arytenoid cartilage or crico-arytenoid unit to the planning open partial horizontal laryngectomy (OPHL) for laryngeal squamous cell carcinoma (LSCC), it is important to have a reliable radiological test to assess impairments of these structures.

Methods: We retrospectively compared the endoscopic, radiological, and pathological findings in patients with glottic LSCC who underwent OPHL.

Results: The endoscopic finding of a reduced (impaired or absent) vocal cord motility proved more sensitive, with better positive and negative predictive values, but less specific than the radiological finding of complete arytenoid sclerosis in detecting histologically assessable infiltration of the arytenoid cartilage.

Contemporary neurosciences have grown beyond the limits of a natural science. To its most vocal advocates, the study of the human brain can provide nothing short of the basis for a new science of man-the link between the "natural" and "human" sciences-as a simple consequence of the growing mass of facts relating to this most marvelous organ, accumulated in the last four decades. This straightforward picture of the growing import of the neurosciences simplifies and obscures the myriad different interpretations and images of "the brain" that have inspired the development of the neurosciences.

Department of Herpetology, Chengdu Institute of Biology, Chinese Academy of Sciences, No.9 Section 4, Renmin South Road, Chengdu, Sichuan, People's Republic of China

Sex differences in both vocalization and auditory processing have been commonly found in vocal animals, although the underlying neural mechanisms associated with sexual dimorphism of auditory processing are not well understood. In this study we investigated whether auditory perception exhibits sexual dimorphism in To do this we measured event-related potentials (ERPs) evoked by white noise (WN) and conspecific calls in the telencephalon, diencephalon and mesencephalon respectively. Results showed that (1) the N1 amplitudes evoked in the right telencephalon and right diencephalon of males by WN are significantly different from those evoked in females; (2) in males the N1 amplitudes evoked by conspecific calls are significantly different from those evoked by WN; (3) in females the N1 amplitude for the left mesencephalon was significantly lower than for other brain areas, while the P2 and P3 amplitudes for the right mesencephalon were the smallest; in contrast these amplitudes for the left mesencephalon were the smallest in males.

Departments of Psychiatry, Neuroscience, and Comparative Medicine, Yale School of Medicine, New Haven, CT, USA; Department of Medical Physics and Biomedical Engineering, University College London, UK.

Previous studies in animals and humans suggest the periaqueductal grey region (PAG) is a final integration station between the brain and laryngeal musculature during phonation. To date, a limited number of functional magnetic neuroimaging (fMRI) studies have examined the functional connectivity of the PAG during volitional human phonation. An event-related, stimulus-induced, volitional movement paradigm was used to examine neural activity during sustained vocalization in neurologically healthy adults and was compared to controlled exhalation through the nose.

The rise and fall of dialects in northern elephant seals.

Proc Biol Sci 2018 Nov 28;285(1892). Epub 2018 Nov 28.

Department of Ecology and Evolutionary Biology, University of California Santa Cruz, Long Marine Laboratory, 130 McAllister Way, Santa Cruz, CA 95060, USA.

Vocal dialects are fundamental to our understanding of the transmission of social behaviours between individuals and populations, however few accounts trace this phenomenon among mammals over time. Northern elephant seals () provide a rare opportunity to examine the trajectory of dialects in a long-lived mammalian species. Dialects were first documented in the temporal patterns of the stereotyped vocal displays produced by breeding males at four sites in the North Pacific in 1968 and 1969, as the population recovered from extreme exploitation.
