  Title Chapter 17 – Split-Brain, Split-Mind Type (up) Book Chapter
  Year 2016 Publication The Neurology of Conciousness (Second Edition) Abbreviated Journal  
  Volume Issue Pages 271-279  
  Keywords Split-brain; consciousness; lateralization; modular; left hemisphere interpreter  
  Abstract The corpus callosum anatomically and functionally connects the two cerebral hemispheres. Despite its important role in interhemispheric communication however, severing the corpus callosum produces few--if any--noticeable cognitive or behavioral abnormalities. Incredibly, split-brain patients do not report any drastic changes in their conscious experience even though nearly all interhemispheric communication ceases after surgery. Extensive research has shown that both hemispheres remain conscious following disconnection and the conscious experience of each hemisphere is private and independent of the other. Additionally, the conscious experiences of the hemispheres appear to be qualitatively different, such that the consciousness of the left hemisphere is more enriched than the right. In this chapter, we offer explanations as to why split-brain patients feel unified despite possessing dual conscious experiences and discuss how the divided consciousness of split-brain patients can inform current theories of consciousness.

  Title Gibt die sensorische Lateralität im Objekttest Aufschluss über das Interieur, den aktuellen Gemütszustand, oder den Trainingszustand der Pferde? Type (up) Conference Article
  Year 2016 Publication 33. FFP-Jahrestagung Abbreviated Journal  
  Volume Issue Pages  
  Keywords  
  Abstract Vor dem obersten Ziel der klassischen Ausbildungsskala für Pferde, die Versammlung, steht das Geraderichten. Ein jedes Pferd ist jedoch von Geburt an asymmetrisch, also schief. Hinter dieser Schiefe verbirgt sich nicht nur die natürliche Schiefe (asymmetrische muskuläre Entwicklung der beiden Körperhälften), die von Geburt an zu beobachten ist, sondern auch die sensorische und motorische Lateralität, also dem ungleichmäßigen Gebrauch der rechten oder linken Sinnesorgane sowie Gliedmaßen, der sich mit der Reifung des Gehirns entwickelt. Alle drei müssen als eigenständige Faktoren, die sich gegenseitig beeinflussen, gesehen werden (Krüger 2014). Um den Weg des Geraderichtens zu erleichtern, sollte in der Ausbildung eines Pferdes nicht nur an der natürlichen Schiefe gearbeitet werden, sondern auch die sensorische und motorische Lateralität beachtet werden um den Prozess des Geraderichtens für das Pferd zu erleichtern. Die sensorische und motorische Lateralität resultiert aus der Aufgabenteilung/Spezialisierung beider Gehirnhälften (Hemisphären) (Rogers 2010). Die rechte Hemisphäre ist dabei für die Verarbeitung von Emotionen (z.B. Angst, Aggression, Freude, Zufriedenheit) sowie für lebenserhaltende Spontanreaktionen zuständig. Die linke Hemisphäre ist für die rationale Verarbeitung von Informationen essentiell (Adolphs et al. 1996, Rogers 2010, Austin und Rogers 2012, De Boyer Des Roches et al. 2008, Demaree et al. 2005, Austin und Rogers 2014). Rückschlüsse auf die Informationsverarbeitung lassen sich über die Beobachtung der verwendeten Sinnesorgane (Ohren und Augen) ziehen, die kontralateral mit den Großhirnhemisphären verbunden sind (Brooks et al. 1999). Es wird vermutet, dass Stress zu einer verstärkten Informationsverarbeitung durch die rechte Großhirnhemisphäre führt (Rogers 2010, Schultheiss et al. 2009). Diese konnte auch in ersten Untersuchungen am Pferd bestätigt werden (unveröffentlichte Daten). Forscher, die den einseitigen Gebrauch von rechten und linken Gliedmaßen (motorische Lateralität) bei Menschen und Tieren untersuchten, zeigten weiterhin Zusammenhänge zur Emotionalität und Reaktivität (McGreevy und Thomson 2006, Rogers 2009, Austin und Rogers 2012, Deesing und Grandin 2014). Die Tendenz zum einseitigen Gebrauch der Gliedmaßen gibt Hinweise auf den „Cognitive Bias“ (= individuelle, kognitive Verzerrung der Wahrnehmung und Verarbeitung von Informationen ins Positive oder Negative) und steht im Zusammenhang mit der persönlichen Neigung auf Stressfaktoren zu reagieren (zusammengefasst von Rogers 2010). Die sensorische Lateralität ändert sich jedoch schneller und situationsgebundener als die motorische Lateralität. Sie wird mittels Objekttests bestimmt, die ebenfalls verwendet werden können um die Reaktivität und Emotionalität zu untersuchen. Für eine objektivere Beurteilung des Interieurs eines Pferdes ist daher zu überlegen, ob die sensorische Lateralität als objektiver Parameter integriert werden kann, welchen Einflüssen diese unterliegt und mit welchen Persönlichkeitsmerkmalen sie korreliert. Wie in der Studie von Farmer et al. (2010) dargestellt werden konnte, zeigten bilateral trainierte Pferde eine weniger stark ausgeprägte Präferenz für die linken Sinnesorgane als traditionell trainierte Pferde in Tests mit Personen (ohne Interaktion). Es stellt sich daher die Frage, ob diese Beobachtung ein Resultat von langjährigem Training ist oder ob es sich bereits nach wenigen Wochen Training einstellt sowie ob solche Entwicklungen auch bei Objekten beobachtet werden können.

Für die erste Untersuchung ergaben sich daher in dieser Studie folgende Fragstellungen: Sind die Ergebnisse eines Objekttests mit Evaluierung der sensorischen Lateralität hinsichtlich der Lateralität wiederholbar? Denn, sollte es möglich sein mittels der sensorische Lateralität auf bestimmte

Persönlichkeitsmerkmale rückschließen zu können, so muss diese genauso stabil und reproduzierbar sein, wie die betreffenden Persönlichkeitsmerkmale. Unterscheiden sich Pferde hinsichtlich ihrer Lateralität in Objekttests, die bereits intensiv gleichmäßig beidseitig trainiert wurden, von Pferden, bei denen weniger Augenmerk auf gleichmäßiges beidseitiges Training gelegt wurde? Kann die Lateralität in Objekttests mit einer definierten gleichmäßigen beidseitigen Trainingsmethode beeinflusst werden? In welche Richtung verschiebt sich gegebenenfalls die Lateralität? Beeinflusst das Alter gegebenenfalls das Ausmaß von Veränderungen, da sich die sensorische Lateralität mit der Reifung des Gehirns entwickelt?

  Abstract Abstract— We present a study focused on a quantitative estimation of a human-horse dynamic interaction. A set of measures based on magnitude and phase coupling between heartbeat dynamics of both humans and horses in three different conditions is reported: no interaction, visual/olfactory interaction and grooming. Specifically, Magnitude Squared Coherence (MSC), Mean Phase Coherence (MPC) and Dynamic Time Warping (DTW) have been used as estimators of the amount of coupling between human and horse through the analysis of their heart rate variability (HRV) time series in a group of eleven human subjects, and one horse. The rationale behind this study is that the interaction of two complex biological systems go towards a coupling process whose dynamical evolution is modulated by the kind and time duration of the interaction itself. We achieved a congruent and consistent

statistical significant difference for all of the three indices. Moreover, a Nearest Mean Classifier was able to recognize the three classes of interaction with an accuracy greater than 70%. Although preliminary, these encouraging results allow a discrimination of three distinct phases in a real human-animal interaction opening to the characterization of the empirically proven relationship between human and horse.

  Title Examining dog–human play: the characteristics, affect, and vocalizations of a unique interspecific interaction Type (up) Journal Article
  Year 2016 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume Issue Pages 1-10  
  Keywords  
  Abstract Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such routine: dog–human play. Dyadic interspecific play is known to be a common interaction between owner and charge, but the details of what counts as play have not been thoroughly researched. Similarly, though people represent that “play” is pleasurable, no study has yet undertaken to determine whether different forms of play are associated with different affective states. Thus, we aimed to generate an inventory of the forms of dyadic play, the vocalizations within play, and to investigate the relationship of affect to elements of play. Via a global citizen science project, we solicited videotapes of dog–human play sessions from dog owners. We coded 187 play bouts via frame-by-frame video playback. We then assessed the relationship between various intra-bout variables and owner affect (positive or neutral) during play (dog affect was overwhelmingly positive). Amount of physical contact (“touch”), level of activity of owner (“movement”), and physical closeness of dog–owner dyad (“proximity”) were highly correlated with positive affect. Owner vocalizations were found to contain different elements in positive- and neutral-affect play. One novel category of play, “tease”, was found. We conclude that not all play is created equal: the experience of play to the owner participant is strongly related to a few identifiable characteristics of the interaction.

  Title Reciprocity in group-living animals: partner control versus partner choice Type (up) Journal Article
  Year 2016 Publication Biological Reviews Abbreviated Journal Biol Rev  
  Volume 92 Issue 2 Pages 665-672  
  Keywords cooperation; reciprocity; partner control; partner choice; proximate mechanisms  
  Abstract ABSTRACT Reciprocity is probably the most debated of the evolutionary explanations for cooperation. Part of the confusion surrounding this debate stems from a failure to note that two different processes can result in reciprocity: partner control and partner choice. We suggest that the common observation that group-living animals direct their cooperative behaviours preferentially to those individuals from which they receive most cooperation is to be interpreted as the result of the sum of the two separate processes of partner control and partner choice. We review evidence that partner choice is the prevalent process in primates and propose explanations for this pattern. We make predictions that highlight the need for studies that separate the effects of partner control and partner choice in a broader variety of group-living taxa.

  Title Expression of Tight Junction Proteins and Cadherin 17 in the Small Intestine of Young Goats Offered a Reduced N and/or Ca Diet Type (up) Journal Article
  Year 2016 Publication PLoS ONE Abbreviated Journal PLoS ONE  
  Volume 11 Issue 4 Pages e0154311  
  Keywords  
  Abstract <p>Diets fed to ruminants should contain nitrogen (N) as low as possible to reduce feed costs and environmental pollution. Though possessing effective N-recycling mechanisms to maintain the N supply for rumen microbial protein synthesis and hence protein supply for the host, an N reduction caused substantial changes in calcium (Ca) and phosphate homeostasis in young goats including decreased intestinal transepithelial Ca absorption as reported for monogastric species. In contrast to the transcellular component of transepithelial Ca transport, the paracellular route has not been investigated in young goats. Therefore, the aim of the present study was to characterise the effects of dietary N and/or Ca reduction on paracellular transport mechanisms in young goats. Electrophysiological properties of intestinal epithelia were investigated by Ussing chamber experiments. The expression of tight junction (TJ) and adherens junction (AJ) proteins in intestinal epithelia were examined on mRNA level by <italic>q</italic>PCR and on protein level by western blot analysis. Dietary N reduction led to a segment specific increase in tissue conductances in the proximal jejunum which might be linked to concomitantly decreased expression of cadherin 17 mRNA. Expression of occludin (OCLN) and zonula occludens protein 1 was increased in mid jejunal epithelia of N reduced fed goats on mRNA and partly on protein level. Reduced dietary Ca supply resulted in a segment specific increase in claudin 2 and claudin 12 expression and decreased the expression of OCLN which might have been mediated at least in part by calcitriol. These data show that dietary N as well as Ca reduction affected expression of TJ and AJ proteins in a segment specific manner in young goats and may thus be involved in modulation of paracellular Ca permeability.</p>

  Title Functionally relevant responses to human facial expressions of emotion in the domestic horse (Equus caballus) Type (up) Journal Article
  Year 2016 Publication Biology Letters Abbreviated Journal Biol. Lett.  
  Volume 12 Issue 2 Pages  
  Keywords  
  Abstract Whether non-human animals can recognize human signals, including emotions, has both scientific and applied importance, and is particularly relevant for domesticated species. This study presents the first evidence of horses' abilities to spontaneously discriminate between positive (happy) and negative (angry) human facial expressions in photographs. Our results showed that the angry faces induced responses indicative of a functional understanding of the stimuli: horses displayed a left-gaze bias (a lateralization generally associated with stimuli perceived as negative) and a quicker increase in heart rate (HR) towards these photographs. Such lateralized responses towards human emotion have previously only been documented in dogs, and effects of facial expressions on HR have not been shown in any heterospecific studies. Alongside the insights that these findings provide into interspecific communication, they raise interesting questions about the generality and adaptiveness of emotional expression and perception across species.

  Title Behavioural and physiological measures indicate subtle variations in the emotional valence of young pigs Type (up) Journal Article
  Year 2016 Publication Physiology & Behavior Abbreviated Journal Physiol. Behav.  
  Volume 157 Issue Pages 116-124  
  Keywords Emotion; Heart rate; Vocalisation; Emotional valence; Animal welfare; Domestic pig  
  Abstract Abstract In the study of animal emotions, emotional valence has been found to be difficult to measure. Many studies of farm animals' emotions have therefore focussed on the identification of indicators of strong, mainly negative, emotions. However, subtle variations in emotional valence, such as those caused by rather moderate differences in husbandry conditions, may also affect animals' mood and welfare when such variations occur consistently. In this study, we investigated whether repeated moderate aversive or rewarding events could lead to measurable differences in emotional valence in young, weaned pigs. We conditioned 105 female pigs in a test arena to either a repeated startling procedure (sudden noises or appearances of objects) or a repeated rewarding procedure (applesauce, toy and straw) over 11 sessions. Control pigs were also regularly exposed to the same test arena but without conditioning. Before and after conditioning, we measured heart rate and its variability as well as the behavioural reactions of the subjects in the test arena, with a special focus on detailed acoustic analyses of their vocalisations. The behavioural and heart rate measures were analysed as changes compared to the baseline values before conditioning. A limited number of the putative indicators of emotional valence were affected by the conditioning. We found that the negatively conditioned pigs showed changes that were significantly different from those in control pigs, namely a decrease in locomotion and an increase in standing. The positively conditioned pigs, however, showed a stronger increase in heart rate and a smaller decrease in SDNN (a heart rate variability parameter indicating changes in autonomic regulation) compared to the controls. Compared to the negatively conditioned pigs, the positively conditioned pigs produced fewer vocalisations overall as well as fewer low-frequency grunts but more high-frequency grunts. The low-frequency grunts of the negatively conditioned pigs also showed lower frequency parameters (bandwidth, maximum frequency, 25% and 50% quartiles) compared to those of the positively conditioned pigs. In any of the statistically significant results, the conditioning accounted for 1.5–11.9% of variability in the outcome variable. Hence, we conclude that repeated moderate aversive and rewarding events have weak but measurable effects on some aspects of behaviour and physiology in young pigs, possibly indicating changes in emotional valence, which could ultimately affect their welfare. The combination of ethophysiological indicators, i.e., the concurrent examination of heart rate measures, behavioural responses and especially vocalisation patterns, as used in the current study, might be a useful way of examining subtle effects on emotional valence in further studies.
