The 41st Annual Meeting of the J.B. Johnston Club for Evolutionary Neuroscience and the 33rd Annual Karger Workshop in Evolutionary Neuroscience.

The 2021 meetings of the J.B. Johnston Club for Evolutionary Neuroscience and Karger Workshop in Evolutionary Neuroscience is typically held immediately before the annual meeting of the Society for Neuroscience. This year the Karger Workshop will be held on Thursday, November 11. The regular JBJC meeting will be held on Friday, November 12. Due to the COVID-19 pandemic, both meetings will be held virtually. This year's Karger Workshop in Evolutionary Neuroscience, made possible by the continuing support of Karger Publishers, is organized by Loreta Medina and Ester Desfilis. It is titled "Conservation, divergence and convergence in amygdala evolution". The Workshop will examine new findings about some controversial issues of this complex brain structure that in mammals is known to be critical for regulating emotions, social behavior and cognition, but whose identification in non-mammals and the evolution thereof have been highly a matter of vivid discussion. The workshop participants treat the subject from various perspectives that introduce the expression of the amygdala in different species of vertebrates and consider distinct developmental and evolutionary mechanisms. On the following day, the program for the annual JBJC meeting will consist of 24 talks submitted by JBJC members and selected by the JBJC Program Committee (Werner Graf, Alice Powers, Andrew Iwaniuk). Additional information and the final schedule of talks will be mailed to JBJC members before the meeting and posted on the JBJC web site (www.jbjclub.org).
