Description of lab research areas
The brain is geared to support attention and memory, two crucial gating actions that enable adaptive behavior and learning, augmenting our interaction with the world.
Mechanisms of attention limit sensory processing, filtering irrelevant information, whereas memory filters experiences according to their salience, encoding important events for long-term storage, and effectively defining self-identity and future behavior based on past experience.
Consistent with this view, the research program of the Citri lab follows two main trajectories, addressing fundamental aspects of brain function in mice:
A) Probing the circuit basis of attention, with a specific focus on the hypothesized role of the claustrum in selective attention. To this end we are applying integrated approaches to decipher the principles defining the circuit organization of the claustrum, its physiological functions, and its roles in behavior.
B) Studying the molecular and neural circuit mechanisms supporting adaptive and maladaptive experience-dependent plasticity, underlying the development of habits, compulsions and addiction. We focus on striatal circuits, applying a broad range of molecular-genetic approaches for circuit analysis and manipulation.
In order to comprehensively address these research questions, we have developed a comprehensive toolkit of fine-grained integrated experimental approaches in our lab, covering behavior, physiology, anatomy and transcription. For example, we implement detailed investigation of transcription using RNAseq, microfluidic qPCR, single-cell RNAseq, single-molecule ISH etc’ – providing comprehensive, well controlled and cost-efficient analysis of gene expression with high spatial resolution. Similarly, in order to address complex behaviors, we have developed automated behavior systems, which support multi-modal individualized training of multiple mice co-housed in their homecage environment, as well as smooth transition to head-fixed and freely moving setups for optical (multiplexed fiber photometry) and electrophysiological (single cell, multi-unit and neuropixels) recordings. We have similarly developed approaches for opto- and chemo- genetic perturbation of anatomically or genetically defined neuronal populations in order to address their impact on circuit physiology, and their behavioral roles.
These examples are intended to provide the flavor of our labs’ approach –fearlessly pursuing the implementation of cutting-edge techniques necessary to push the envelope.
