Nannofossil biostratigraphy, strontium and carbon isotope stratigraphy, cyclostratigraphy and an astronomically calibrated duration of the Late Campanian Radotruncana calcarata Zone

AbstractA section from the southern (Austro-Alpine Northern Calcareous Alps) margin of the Penninic Ocean in the NW Tethys realm of Late Campanian age is investigated stratigraphically. Plankton foraminifer and nannofossil biostratigraphy designate the presence of the Globotruncana ventricosa Zone and the Radotruncana (Globotruncanita) calcarata Zone, and standard nannofossil zones CC21–UC15cTP and CC22ab–UC15deTP. The combination of carbon isotope stratigraphy, strontium isotopes, and cyclostratigraphy allows a detailed chronostratigraphic correlation. Periodicity was obtained by power spectral analysis, sinusoidal regression, and Morlet wavelets. The duration of the calcarata Total Range Zone is calculated by orbital cyclicity expressed in thickness data of limestone–marl rhythmites and stable carbon isotope data. Precessional, obliquity, and short and long eccentricity cycles are identified and give an extent of c. 806kyr for the zone. Mean sediment accumulation rates are as low as 1.99cm/kyr and correspond well to sediment accumulation rates in similar settings. We further discuss chronostratigraphic implications of our data

Corrigendum to “Functional anatomy of the vagus system: How does the polyvagal theory comply?” [Biological Psychology 174 (2022) 108425] (Biological Psychology (2022) 174, (S0301051122001685), (10.1016/j.biopsycho.2022.108425))

In the published version on page 5, subchapter 5.1 Heart and large arteries, right column, the paper by Booth et al. (2021) was erroneously quoted as describing DMX cardiac neurons conducting at about B-fiber speed. However, these authors only described DMX neurons in general and not specifically cardiac neurons. Thus, the term “cardiac” should be deleted in lines 7 and 9. Also, in line 7, conduction speed should be 6 m/s

Functional anatomy of the vagus system – Emphasis on the somato-visceral interface

Due to its pivotal role in autonomic networks, the vagus attracts continuous interest from both basic scientists and clinicians. In particular, recent advances in vagus nerve stimulation strategies and their application to pathological conditions beyond epilepsy provide a good opportunity to recall basic features of vagal peripheral and central anatomy. In addition to the “classical” vagal brainstem nuclei, i.e., dorsal motor nucleus, nucleus ambiguus and nucleus tractus solitarii, the spinal trigeminal and paratrigeminal nuclei come into play as targets of vagal afferents. On the other hand, the nucleus of the solitary tract receives and integrates not only visceral but also somatic afferents. Thus, the vagus system participates significantly in what may be defined as “somato-visceral interface”

Im Zuge folgender Forschung wird der TV-Werbespot als Untersuchungsgegenstand herangezogen. Neben einer Darstellung üblicher Strategien der indirekten Beeinflussung der Rezipienten durch die Werbung ist für diese Arbeit relevant, welche Auswirkungen die Konditionierung durch auditive Botschaftsvermittlung auf die Wahrnehmung und in weiterer Folge Bindung der Rezipienten an eine Marke hat bzw. wie Musik im TV-Spot die Wahrnehmung des Produktes verändert. Ausgehend von aktuellen Untersuchungen zu der Thematik Audio Branding (Vgl. Bronner/Hirt 2007, als auch Zander/Kapp 2007, Krugmann 2007, Ringe 2005 etc.) findet eine quasi-experimentelle Untersuchung mittels der Methoden Denke Laut, Freie Assoziationen und einer Gruppendiskussion statt. Die Erkenntnisse dieser qualitativen Forschungsarbeit - eingebettet in die Ergebnisse marktorientierter Forschungen - sollen den Rezipienten in den Mittelpunkt rücken und weiters offenlegen, ob eine kritische Wahrnehmung des Mediums Musik gekoppelt an visuelle Reize in der Fernsehwerbung vorhanden ist

Sensory spinal interoceptive pathways and energy balance regulation

Interoception plays an important role in homeostatic regulation of energy intake and metabolism. Major interoceptive pathways include gut-to-brain and adipose tissue-to brain signaling via vagal sensory nerves and hormones, such as leptin. However, signaling via spinal sensory neurons is rapidly emerging as an additional important signaling pathway. Here we provide an in-depth review of the known anatomy and functions of spinal sensory pathways and discuss potential mechanisms relevant for energy balance homeostasis in health and disease. Because sensory innervation by dorsal root ganglia (DRG) neurons goes far beyond vagally innervated viscera and includes adipose tissue, skeletal muscle, and skin, it is in a position to provide much more complete metabolic information to the brain. Molecular and anatomical identification of function specific DRG neurons will be important steps in designing pharmacological and neuromodulation approaches to affect energy balance regulation in disease states such as obesity, diabetes, and cancer
