The J. B. Johnston Club meets annually, on the two days before the meeting of the Society for Neuroscience. The first day is devoted to the annual Karger Workshop, a one-day symposium on a specific topic in comparative or evolutionary neurobiology, organized by one or more members of the Club and sponsored by S. Karger AG. The Proceedings of the Workshop are published in the Club’s official journal, Brain, Behavior, and Evolution.

The second day of the meeting comprises presentations by members, which are selected by the Program Committee from abstracts submitted by members. Receptions are held at the end of each day for further socializing.

The 35th Karger workshop in Evolutionary Neuroscience is being organized by Carmen Falcone , and is titled
The Evolution and Diversification of glia across invertebrates and vertebrates. The Karger Workshop will be held on Thursday, November 9th, 2023 at Howard University in Washington, DC.
