Department of
Physiology and Neurobiology

We carry out research and education that is innovative, collaborative, and centered on cutting-edge science. We bring together researchers and educators focused on the molecular, cellular, and circuit-based mechanisms that underlie diverse functions orchestrated by the brain and body. By integrating work across the spectrum of Physiology and Neurobiology, we aim to advance our understanding of brain-body functions and interactions under normal conditions and disease.

  • An opto-microperfusion neural probe for multiplexed detection of optogenetically evoked neurochemical release dynamics October 6, 2026
    Probing the spatiotemporal release dynamics of multiple neurochemicals simultaneously in vivo is essential for understanding the molecular basis of brain function and behavior. Microdialysis enables multiplexed neurochemical analysis when combined with advanced molecular tools such as mass spectrometry, but existing microdialysis probes typically exhibit low recovery rates and provide temporal resolution of several minutes, which […]

  • Locus coeruleus activation transforms cortical taste representations September 16, 2026
    Noradrenergic neurons in the locus coeruleus (LC) shape sensory processing, yet how LC activity influences population taste coding remains unclear. Using optogenetic LC activation with miniscope imaging in the gustatory cortex (GC), we examined LC modulation of multiple taste attributes. Phasic LC activation strengthens correlations between neuronal responses and palatability and expands the dynamic range […]

  • Carotid body dysfunction contributes to respiratory instability in Rett syndrome September 1, 2026
    Rett syndrome (RTT) is a neurodevelopmental disorder caused by mutations in MECP2. Disordered breathing is a hallmark feature of RTT that negatively impacts quality of life and can be life-threatening. Despite this, the mechanisms underlying disordered breathing in RTT are poorly understood. Although RTT is primarily considered a central nervous system disorder, we found that […]

  • Identification of markers facilitating the study of support cells in adult olfactory sensilla in Drosophila August 12, 2026
    In the Drosophila antenna, olfactory sensilla are the fundamental unit of odor detection and processing. Sensilla house one to four olfactory neurons enwrapped by three distinct support cells: thecogen, trichogen, and tormogen cells. While olfactory neurons and their odor receptors have been extensively studied in Drosophila, and increasingly in other insect species, much less is […]

  • Brain-Wide Mapping and Synaptic Localization of C1QL3 Using a Novel Epitope-Tagged Knock-In Mouse August 7, 2026
    Synapse formation and function are coordinated spatially and temporally by a host of synaptic proteins that regulate neuronal signaling, synapse specificity, and plasticity, many of which are implicated in neuropsychiatric disorders. Many members of the C1q/TNF superfamily function as synaptic organizers, shaping synapse assembly and maintenance. Among them, C1QL3 plays a putative role in trans-synaptic […]

  • Bayesian Transformers and Higher-Order Graph Matching for Cell Tracking in Serial Tissue Sections May 26, 2026
    Reliable 3D reconstruction of tissue architecture from sequential 2D multiplex images is challenging due to the noise and distortions introduced by ultrathin (50 nm) slicing and complex alignment procedures. Conventional cell tracking methods often fail under such conditions, resulting in inaccurate linkage of cells across sections. To bridge this gap, we propose a Bayesian Transformer […]

  • Dynamic cholinergic signaling differentially desynchronizes cortical microcircuits dependent on modulation rate and network connectivity April 10, 2026
    Acetylcholine (ACh) affects both the intrinsic properties of individual neurons and the oscillatory tendencies of cortical microcircuits by modulating the muscarinic-receptor gated m-current. ACh concentrations have historically been assumed to vary exclusively over long (supra-second) neuromodulatory timescales, conventionally simplified in silico as a set and constant modulatory tone. However, contemporary experimental studies show cortical ACh […]

  • Cellular properties and axonal projections of thyrotropin-releasing hormone-expressing neurons in the mouse lateral hypothalamic area March 17, 2026
    The lateral hypothalamic area (LHA) is well-known for its conserved role in modulating and driving many forms of innate behaviors, yet the cellular diversity underlying these functions remains incompletely understood. Although neurons expressing the neuropeptide thyrotropin-releasing hormone (TRH) in the hypothalamic paraventricular nucleus have been well-characterized for their hypophysiotropic functions and role in metabolism and […]

  • Minor spliceosome inhibition via ablation of its U11 snRNA gene results in multiple defects in murine spermatogenesis February 25, 2026
    Minor intron-containing genes (MIGs), which require the minor spliceosome (MiS) for their splicing, are highly represented among genes involved in mouse spermatogenesis. Leveraging gene- and intron-level ortholog data, we show that conservation of these genes as MIGs is particularly strong in chordates but not in other species groups, suggesting lineage-specific changes to their splicing regulation. […]

  • Astrocytes enable amygdala neural representations supporting memory February 11, 2026
    Brain systems mediating responses to previously encountered threats provide critical survival functions. Fear memory and extinction are underpinned by neural representations in the basolateral amygdala (BLA)^(1-7), but the contribution of non-neuronal cells, including astrocytes, to these processes remains unresolved. Here, using in vivo calcium (Ca^(2+)) imaging and causal astrocyte manipulations, we find that BLA astrocytes […]

  • Identity rather than 3D position informs splicing of rare introns in the human genome January 21, 2026
    Three-dimensional genome organization influences splicing, yet how introns, particularly rare introns, are arranged within the nucleus and whether this organization contributes to splicing have not been fully explored. We mapped the organization of six intron classes, major, minor, minor-like, hybrid, major-like, and non-canonical, across four human cell lines using Hi-C, TSA-seq, and DamID-seq. Minor intron-containing […]

  • Mislocalization of KCNQ2 Channels as a Pathogenic Mechanism in KCNQ2 Developmental and Epileptic Encephalopathy December 19, 2025
    KCNQ2 potassium channel variants are linked to developmental and epileptic encephalopathy (DEE). However, the mechanisms by which pathogenic variants, especially those outside known hotspots, such as the S4-S5 linker, lead to disease remain unknown. Here, we examined the H228R variant, a pathogenic mutation in the S4-S5 linker associated with DEE. We tested whether H228R induces […]
