Current Research and Scholarly InterestsWe study how the neural circuitry of the vertebrate retina encodes visual information and performs computations. To control and measure the retinal circuit, we present visual images while performing simultaneous two-photon imaging and multielectrode recording. We perturb the circuit as it operates using simultaneous intracellular current injection and multielectrode recording, and use the resulting large data sets to construct models of retinal computation.

Current Research and Scholarly InterestsThe Clandinin lab focuses on understanding how neuronal circuits assemble and function to perform specific computations and guide behavior. Taking advantage of a rich armamentarium of genetic tools available in the fruit fly, combined with imaging, physiology and analytical techniques drawn from systems neuroscience, we examine a variety of visual circuits.

Current Research and Scholarly InterestsOur research goal is to understand how dynamics in neuronal circuits relate and constrain the representation of information and computations upon it. We adopt three synergistic strategies: First, we analyze neural circuit population recordings to better understand the relation between neural dynamics and behavior, Second, we theoretically explore the types of dynamics that could be associated with particular network computations. Third, we analyze the structural properties of neural circuits.

Current Research and Scholarly InterestsMy laboratory studies the cellular and molecular mechanisms underlying the organization of cortical circuits important for spatial navigation and memory. We are particularly focused on medial entorhinal cortex, where many neurons fire in spatially specific patterns and thus offer a measurable output for molecular manipulations. We combine electrophysiology, genetic approaches and behavioral paradigms to unravel the mechanisms and behavioral relevance of non-sensory cortical organization. Our first line of research is focused on determining the cellular and molecular components crucial to the neural representation of external space by functionally defined cell types in entorhinal cortex (grid, border and head direction cells). We plan to use specific targeting of ion channels, combined with in vivo tetrode recordings, to determine how channel dynamics influence the neural representation of space in the behaving animal. A second, parallel line of research, utilizes a combination of in vivo and in vitro methods to further parse out ionic expression patterns in entorhinal cortices and determine how gradients in ion channels develop. Ultimately, our work aims to understand the ontogenesis and relevance of medial entorhinal cortical topography in spatial memory and navigation.

Current Research and Scholarly InterestsOur laboratory studies the mechanisms by which highly complex behaviors are mediated at the neuronal level, mainly focusing on the example of dynamic social interactions and the neural circuits that drive them. From dyadic interactions to group dynamics and collective decision making, the lab seeks a mechanistic understanding for the fundamental building blocks of societies, such as cooperation, empathy, fairness and reciprocity.

Current Research and Scholarly InterestsIn 2017, we developed a virtual reality platform to investigate the neural and autonomic mechanisms contributing to fear and anxiety. That involved capturing 360-degree videos of various fear-provoking situations in real life for in-lab VR movies, such as heights and claustrophobia, as well as unusual scenarios like swimming in open water with great white sharks. The primary objective of our VR platform is to develop new tools to help people better manage stress, anxiety and phobias in real-time, as an augment to in-clinic therapies.
In May 2018, we reported the discovery of two novel mammalian brain circuits as a Research Article published in Nature. One circuit promotes fear and anxiety-induced paralysis, while the other fosters confrontational reactions to threats. This led to ongoing research into the involvement of these brain regions in anxiety-related disorders such as phobias and generalized anxiety in humans.
In 2020, we embarked on a collaborative effort with Dr. David Spiegel's laboratory in the Stanford Department of Psychiatry and Behavioral Sciences, aimed to explore how specific respiration patterns synergize with the visual system to influence autonomic arousal and stress, and other brain states, including sleep.
In 2023, the first results of that collaboration were published as a randomized controlled trial in Cell Reports Medicine, demonstrating that specific brief patterns of deliberate respiration are particularly effective in alleviating stress and enhancing mood, and improving sleep.
In a 2021, our collaboration with Dr. Edward Chang, professor and chair of the Department of Neurological Surgery at the University of California, San Francisco (UCSF), was published in Current Biology, revealing that specific patterns of insular cortex neural activity may be linked to, and potentially predict, anxiety responses.

Current Research and Scholarly InterestsOur lab applies biochemical and engineering principles to the development of protein-based tools for investigating biology in living animals. Topics of investigation include fluorescent protein-based voltage indicators, synthetic light-controllable proteins, bioluminescent reporters, and applications to studying animal models of disease.
