Title: “Developing new tools for imaging network dynamics in freely behaving animals”
Abstract: One of the biggest challenges in neuroscience is to understand how neural circuits in the brain process, encode, store, and retrieve information. Meeting this challenge requires tools capable of recording and manipulating the activity of intact neural networks in freely behaving animals. Head-mounted miniature fluorescence microscopes are among the most promising of these tools. Taking advantage of the past decade of advancements in fluorescent neural activity reports, these microscopes use wide-field single photon excitation to image activity across large populations of neurons in freely behaving animals. They are capable of imaging the same neural population across months and in a wide range of different brain regions.
Initiated six years ago, the Miniscope Project -- an open-source collaborative effort-- aims at accelerating innovation of miniature microscope technology while also extending access to this technology to the entire neuroscience community. Currently, we are working on advancements ranging from optogenetic stimulation and wire-free operation to simultaneous optical and electrophysiology recording. Through continued optimization and innovation, miniature microscopes will likely play a critical role in extending the reach of neuroscience research and creating new avenues of scientific inquiry.

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.
