Title: “ Is there learning in single cells? ”
Abstract: The question of whether single-cells can learn has a long and contentious history. Around 1900, Herbert Spencer Jennings claimed that the single-cell ciliate, Stentor roeseli, exhibited complex avoidance behaviours which he considered to be a form of learning. Jennings' experiments were subsequently judged not to be reproducible and this rejection formed part of the strong consensus that emerged against learning in single cells. I will discuss a skunk-works project from my lab which shows, to the contrary, that Jennings was right and why it is a good time to reconsider our assumptions about the origins of learning.

About Us
Introduction
The Integrative Center for Learning and Memory (ICLM) is a multidisciplinary center of UCLA labs devoted to understanding the neural basis of learning and memory and its disorders. This will require a unified approach across different levels of analysis, including;
1. Elucidating the molecular cellular and systems mechanisms that allow neurons and synapses to undergo the long-term changes that ultimately correspond to 'neural memories'.
2. Understanding how functional dynamics and computations emerge from complex circuits of neurons, and how plasticity governs these processes.
3. Describing the neural systems in which different forms of learning and memory take place, and how these systems interact to ultimately generate behavior and cognition.
History of ICLM
The Integrative Center for Learning and Memory formally LMP started in its current form in 1998, and has served as a platform for many interactions and collaborations within UCLA. A key event organized by the group is the weekly ICLM Journal Club. For more than 10 years, graduate students, postdocs, principal investigators, and invited speakers have presented on topics ranging from the molecular mechanisms of synaptic plasticity, through computational models of learning, to behavior and cognition. Dean Buonomano oversees the ICLM journal club with help of student/post doctoral organizers. For other events organized by ICLM go to http://www.iclm.ucla.edu/Events.html.
