• Source localization of neural substrates required for generating a gamma frequency response to 40Hz GENUS light and sound stimulation

  Alzheimer s & Dementia · 2025-12-01

  articleOpen access

  BACKGROUND: Non-invasive gamma-frequency light and sound stimulation at 40Hz has shown promise as a possible disease modifying therapeutic for the treatment of Alzheimer's disease (AD). However, human neural substrates generating a gamma frequency response to Gamma Entrainment Using Sensory (GENUS) stimulation have never been shown. Here, we aim to show brain regions that generate gamma frequency oscillations in response to GENUS stimulation. METHODS: We conducted an observational trial in cognitively typical subjects (n=16) undergoing magnetoencephalography (MEG) while receiving 40Hz light and sound stimulation with the GENUS device. Neurophysiological data recorded with MEG was mapped on individual T1 structural magnetic resonance (MR) images to deduce source localization of 40Hz oscillation potentiation in the brain. RESULTS: Source localization in response to GENUS light and sound stimulation shows induced 40Hz oscillations in the appropriate sensory cortices as well as in brain regions important for associative, executive and higher order memory functions, memory consolidation, spatial orientation, and integration of sensory processes. Induced 40Hz oscillations are maximal with synchronized 40Hz light and sound stimulation as compared to light or sound stimulation alone. Interestingly, when 40Hz light and sound are anticorrelated, 40Hz oscillations are significantly reduced in the auditory and visual cortices as compared to when 40Hz light and sound are synchronized. CONCLUSIONS: For the first time, we provide evidence of target engagement and sources of gamma wave generation in the brain that are important for sensory processing, associative and executive memory functions and areas affected by AD pathology when humans are undergoing 40Hz GENUS light and sound stimulation. This data set can serve as a resource for exploring responses of neural substrates of 40Hz visual and auditory stimulation.

• Dense, continuous membrane labeling and expansion microscopy visualization of ultrastructure in tissues

  Nature Communications · 2025-02-12 · 14 citations

  articleOpen accessSenior authorCorresponding

  Lipid membranes are key to the nanoscale compartmentalization of biological systems, but fluorescent visualization of them in intact tissues, with nanoscale precision, is challenging to do with high labeling density. Here, we report ultrastructural membrane expansion microscopy (umExM), which combines an innovative membrane label and optimized expansion microscopy protocol, to support dense labeling of membranes in tissues for nanoscale visualization. We validate the high signal-to-background ratio, and uniformity and continuity, of umExM membrane labeling in brain slices, which supports the imaging of membranes and proteins at a resolution of ~60 nm on a confocal microscope. We demonstrate the utility of umExM for the segmentation and tracing of neuronal processes, such as axons, in mouse brain tissue. Combining umExM with optical fluctuation imaging, or iterating the expansion process, yields ~35 nm resolution imaging, pointing towards the potential for electron microscopy resolution visualization of brain membranes on ordinary light microscopes.

• A neural correlate of individual odor preference in Drosophila

  eLife · 2025-03-11 · 6 citations

  articleOpen access

  Behavior varies even among genetically identical animals raised in the same environment. However, little is known about the circuit or anatomical origins of this individuality. Here, we demonstrate a neural correlate of Drosophila odor preference behavior in the olfactory sensory periphery. Namely, idiosyncratic calcium responses in projection neuron (PN) dendrites and densities of the presynaptic protein Bruchpilot in olfactory receptor neuron (ORN) axon terminals correlate with individual preferences in a choice between two aversive odorants. The ORN-PN synapse appears to be a locus of individuality where microscale variation gives rise to idiosyncratic behavior. Simulating microscale stochasticity in ORN-PN synapses of a 3062 neuron model of the antennal lobe recapitulates patterns of variation in PN calcium responses matching experiments. Conversely, stochasticity in other compartments of this circuit does not recapitulate those patterns. Our results demonstrate how physiological and microscale structural circuit variations can give rise to individual behavior, even when genetics and environment are held constant.

• Screening channelrhodopsins using robotic intracellular electrophysiology and single cell sequencing

  bioRxiv (Cold Spring Harbor Laboratory) · 2025-08-24

  preprintOpen access

  Background: Our ability to engineer opsins is limited by an incomplete understanding of how sequence variations influence function. The vastness of opsin sequence space makes systematic exploration difficult. New method: In recognition of the need for datasets linking opsin genetic sequence to function, we pursued a novel method for screening channel-rhodopsins to obtain these datasets. In this method, we integrate advances in robotic intracellular electrophysiology (Patch) to measure optogenetic properties (Excite), harvest individual cells of interest (Pick) and subsequently sequence them (Sequence), thus tying sequence to function. Results: We used this method to sequence more than 50 cells with associated functional characterization. We further demonstrate the utility of this method with experiments on heterogeneous populations of known opsins and single point mutations of a known opsin. Of these point mutations, we found C160W ablates ChrimsonR's response to light. Conclusion and comparison to existing methods: Compared to traditional manual patch clamp screening, which is labor-intensive and low-throughput, this approach enables more efficient, standardized, and scalable characterization of large opsin libraries. This method can enable opsin engineering with large datasets to increase our understanding of opsin sequence-function relationships.

• Self-amplifying RNA enables rapid, durable, integration-free programming of hiPSCs

  bioRxiv (Cold Spring Harbor Laboratory) · 2025-10-24

  preprintOpen access

  Summary Genetic modification of human induced pluripotent stem cells (hiPSCs) is a powerful approach to measure and manipulate the cellular processes underlying differentiation and disease. Conventional genetic engineering of hiPSC lines requires a laborious process involving transfection, selection and expansion that can result in karyotypic abnormalities or transgene silencing during differentiation, limiting their applications. Self-amplifying RNA (saRNA) delivery is a potential alternative integration-free method for durable expression of transgenes. Here, we used saRNA to deliver transcription factors and functional reporters in hiPSCs and demonstrate that expression can persist for weeks. Specifically, saRNA delivery enables highly efficient forward programming to Ngn2-induced neurons and enables measurement of functional reporters over time. We show that a single transfection of saRNA encoded jRCaMP1b reporter in hiPSCs generates sustained expression throughout differentiation to 3D cardiac spheroids. The persistence of the reporter allows measurement of calcium dynamics at a single-cell and population level over weeks, allowing tracking of cardiomyocyte maturation and drug responses. Together, our systematic analysis shows that saRNA provides sustained transgene expression in hiPSCs, supporting integration- free cell-fate programming and measurement of functional reporters in clinically relevant model systems. Highlights A single saRNA transfection generates durable transgene expression saRNA transfection of Ngn2 in hiPSCs results in robust neuronal differentiation saRNA-delivery of functional reporters enables single-cell analysis of primary and hiPSC-derived cells saRNA-based sensor allows monitoring of maturation and drug responses in 3D cardiac spheroids
