Filter Brown Bag Lectures

Brown Bag Lectures are informal, public talks that are followed by extensive dissussions. Speakers are KLI fellows or visiting researchers who are interested in presenting their work to an interdisciplinary audience and discussing it in a wider research context. The Brown Bag Lecture series was discontinued in 2014 with the KLI moving to its new premises in Klosterneuburg. In 2014 the KLI Colloquia were established as the new lecture series.

Topic description:
Research has revealed a variety of left–right asymmetries among vertebrates and invertebrates. In many species, left- and right- lateralized individuals coexist in unequal numbers (‘population-level’ lateralization). It has been argued that brain lateralization increases individual efficiency. However, individual efficiency does not require the alignment of the direction of lateralization in the population. It has thus been hypothesized that the alignment of lateralization at the population level may arise as an evolutionarily stable strategy when individually asymmetrical organisms must coordinate their behavior with that of other asymmetrical organisms. Game-theoretical models in which asymmetric individuals engage in intraspecific and interspecific interactions suggest that population-level lateralization is more likely to evolve in social than in non- social species. Empirical data supporting the hypothesis come from studies comparing social and non-social species of bees.


Biographical note:
Elisa Frasnelli is completing her PhD work at the Center of Mind and Brain Sciences, University of Trento, Italy, focusing her interest on brain lateralization, i.e., the differential functional specialization of the left and right sides of the brain. She is investigating lateralization both from a theoretical point of view, using her mathematical training (she graduated in Physics and Biomedical Tecnologies) and from an experimental point of view, focusing on lateralization in insects. On these topics she published four peer- reviewed papers. She has been a visiting student in the Centre for Neuroscience and Animal Behaviour at the University of New England in Australia.
