  Title Right-nostril use during sniffing at arousing stimuli produces higher cardiac activity in jumper horses Type Journal Article
  Year 2015 Publication Laterality: Asymmetries of Body, Brain and Cognition Abbreviated Journal Laterality  
  Volume 20 Issue 4 Pages 483-500  
  Keywords  
  Abstract (up) Lateralization in horses, Equus caballus, has been reported at both motor and sensory levels. Here we investigated left- and right-nostril use in 12 jumper horses freely sniffing different emotive stimuli. Results revealed that during sniffing at adrenaline and oestrus mare urine stimuli, horses showed a clear right-nostril bias while just a tendency in the use of the right nostril was observed during sniffing of other odours (food, cotton swab and repellent). Sniffing at adrenaline and urine odours was also accompanied by increasing cardiac activity and behavioural reactivity strengthening the role of the right hemisphere in the analysis of intense emotion and sexual behaviour.

  Title Catecholamine plasma levels, IFN-γ serum levels and antibodies production induced by rabies vaccine in dogs selected for their paw preference Type Journal Article
  Year 2013 Publication Laterality: Asymmetries of Body, Brain and Cognition Abbreviated Journal Laterality: Asymmetries of Body, Brain and Cognition  
  Volume 19 Issue 5 Pages 522-532  
  Keywords  
  Abstract (up) To explore the possible role of the sympathetic nervous activity in the asymmetrical crosstalk between the brain and immune system, catecholamine (E, NE) plasma levels, Interferon-? (IFN-?) serum levels and production of antibodies induced by rabies vaccine in dogs selected for their paw preference were measured. The results showed that the direction of behavioural lateralization influenced both epinephrine levels and immune response in dogs. A different kinetic of epinephrine levels after immunization was observed in left-pawed dogs compared to both right-pawed and ambidextrous dogs. The titers of antirabies antibodies were lower in left-pawed dogs than in right-pawed and ambidextrous dogs. Similarly, the IFN-? serum levels were lower in left-pawed dogs than in the other two groups. Taken together, these findings showed that the left-pawed group appeared to be consistently the different group stressing the fundamental role played by the sympathetic nervous system as a mechanistic basis for the crosstalk between the brain and the immune system.

  Title Absence of population asymmetry in the American Quarter Horse (Equus ferus caballus) performing skilled left and right manoeuvres in reining competition Type Journal Article
  Year 2015 Publication Laterality: Asymmetries of Body, Brain and Cognition Abbreviated Journal Laterality  
  Volume 20 Issue 5 Pages 604-617  
  Keywords  
  Abstract (up) Use of the right hand by humans for speech-related hand gestures, writing and throwing exemplifies motoric asymmetry. There are reports of asymmetry in many other animal species, including reports of left preference in emotional responsivity, spontaneous behaviour and the trained performance of the horse, Equus ferus caballus. The present study used the novel approach of using judges' scores to examine asymmetry in an equestrian event. The study analysed the scores of five judges evaluating the reining performance of 482, three-year-old American Quarter Horses competing in a major competition. Reining requires that the horses perform the manoeuvres of spin, circle and stop directed to either the left or right and symmetrical performance is featured in the judging criteria. The scores were sensitive to performance level, sex and manoeuvre, but there was no evidence of a population asymmetry in the left vs. right direction of the manoeuvres. The results are discussed in relation to need of using a large number of subjects in measuring asymmetry, the expression of individual vs. population asymmetry as a function of morphological and behavioural measures, and the influence of behavioural training on asymmetry.

  Title Lateralised visual processing in domestic cattle herds responding to novel and familiar stimuli Type Journal Article
  Year 2009 Publication Laterality: Asymmetries of Body, Brain and Cognition Abbreviated Journal Laterality  
  Volume 15 Issue 5 Pages 514-534  
  Keywords  
  Abstract (up) We investigated whether cattle exhibit preferences to monitor challenging and novel stimuli. Experiments were conducted on dairy and beef cattle herds and revealed significant left eye preferences in the cattle for viewing an experimenter walking to repeatedly split the herd through its centre. Visual lateralisation was demonstrated in the preference to use the left monocular field to monitor the experimenter, alone or equipped with a range of novel stimuli. This finding is consistent with left eye preferences found in various species of mammals, birds, and amphibians responding to predators and novel stimuli. A cohort of the familiarised cattle herds was then subjected to additional herd-splitting tests with the same stimuli and demonstrated a reversal of viewing preferences, preferring to monitor the experimenter and stimuli within the right and not left monocular field. This directional shift in viewing preferences is consistent with experience-dependent learning found in lateralised visual processing in other, non-mammalian, species, and to our knowledge is the first of such studies to suggest that such lateralised learning processes also exist in mammals. Together the data support a number of key hypotheses concerning the evolution and conservation of lateralised brain function in vertebrates, and also provide important considerations for livestock handling.
