    Calcium Imaging of Neuronal Activity under Gradually Changing Odor Stimulation in Caenorhabditis elegans
    Authors:  Yuki Tanimoto and Koutarou D. Kimura, date: 01/05/2021, view: 328, Q&A: 0

    Olfactory behavior is among the most fundamental animal behaviors both in the wild and in the laboratory. To elucidate the neural mechanisms underlying olfactory behavior, it is critical to measure neural responses to odorant concentration changes

    Authors:  Kawssar Harb, Michele Bertacchi and Michèle Studer, date: 01/05/2021, view: 603, Q&A: 0

    The mammalian neocortex, the outer layer of the cerebrum and most recently evolved brain region, is characterized by its unique areal and laminar organization. Distinct cortical layers and areas can be identified by the protein expression of graded

    Establishing an Adult Mouse Brain Hippocampal Organotypic Slice Culture System that Allows for Tracing and Pharmacological Manipulation of ex vivo Neurogenesis
    Authors:  Steffen Mayerl and Charles ffrench-Constant, date: 01/05/2021, view: 384, Q&A: 0

    The function of the hippocampus depends on the process of adult hippocampal neurogenesis which underpins the exceptional neural plasticity of this structure, and is also frequently affected in CNS pathologies. Thus, manipulation of this process

    Authors:  Sung-Jin Lee and Soo-Young Kim, date: 01/05/2021, view: 238, Q&A: 0

    The subretinal layer between retinal pigment epithelium (RPE) and photoreceptors is a region involved in inflammation and angiogenesis during the procession of diseases such as age-related macular degeneration. The current protocols of whole mounts

    A Parkinson’s Disease-relevant Mitochondrial and Neuronal Morphology High-throughput Screening Assay in LUHMES Cells

    Parkinson’s disease is a devastating neurodegenerative disorder affecting 2-3% of the population over 65 years of age. There is currently no disease-modifying treatment. One of the predominant pathological features of Parkinson’s disease

    A Parkinson’s Disease-relevant Mitochondrial and Neuronal Morphology High-throughput Screening Assay in LUHMES Cells
    [Abstract]

    Parkinson’s disease is a devastating neurodegenerative disorder affecting 2-3% of the population over 65 years of age. There is currently no disease-modifying treatment. One of the predominant pathological features of Parkinson’s disease is mitochondrial dysfunction, and much work has aimed to identify therapeutic compounds which can

    Non-separate Mouse Sclerochoroid/RPE/Retina Staining and Whole Mount for the Integral Observation of Subretinal Layer
    Authors:  Sung-Jin Lee and Soo-Young Kim, date: 01/05/2021, view: 238, Q&A: 0
    [Abstract]

    The subretinal layer between retinal pigment epithelium (RPE) and photoreceptors is a region involved in inflammation and angiogenesis during the procession of diseases such as age-related macular degeneration. The current protocols of whole mounts (retina and RPE) are unable to address the intact view of the subretinal layer because the

    Authors:  Steffen Mayerl and Charles ffrench-Constant, date: 01/05/2021, view: 384, Q&A: 0
    [Abstract]

    The function of the hippocampus depends on the process of adult hippocampal neurogenesis which underpins the exceptional neural plasticity of this structure, and is also frequently affected in CNS pathologies. Thus, manipulation of this process represents an important therapeutic goal. To identify potential strategies, organotypic adult brain

    Authors:  Kawssar Harb, Michele Bertacchi and Michèle Studer, date: 01/05/2021, view: 603, Q&A: 0
    [Abstract]

    The mammalian neocortex, the outer layer of the cerebrum and most recently evolved brain region, is characterized by its unique areal and laminar organization. Distinct cortical layers and areas can be identified by the protein expression of graded transcription factors and molecular determinants that define the identity of different projection

    Calcium Imaging of Neuronal Activity under Gradually Changing Odor Stimulation in Caenorhabditis elegans
    Authors:  Yuki Tanimoto and Koutarou D. Kimura, date: 01/05/2021, view: 328, Q&A: 0
    [Abstract]

    Olfactory behavior is among the most fundamental animal behaviors both in the wild and in the laboratory. To elucidate the neural mechanisms underlying olfactory behavior, it is critical to measure neural responses to odorant concentration changes resembling those that animals actually sense during olfactory behavior. However, reproducing the

    Nestlet Shredding and Nest Building Tests to Assess Features of Psychiatric Disorders in Mice
    Authors:  Fabian Dorninger, Gerhard Zeitler and Johannes Berger, date: 12/20/2020, view: 436, Q&A: 0
    [Abstract]

    Mimicking the various facets of human psychiatric and neurodevelopmental disorders in animal models is a challenging task. Nevertheless, mice have emerged as a widely used model system to study pathophysiology and treatment strategies for these diseases. However, the corresponding behavioral tests are often elaborate and require extensive

    Whole-mount Immunohistochemistry of Adult Zebrafish Retina for Advanced Imaging
    Authors:  Mikiko Nagashima and Peter F. Hitchcock, date: 12/20/2020, view: 607, Q&A: 0
    [Abstract]

    Immunohistochemistry is a widely used technique to examine the expression and subcellular localization of proteins. This technique relies on the specificity of antibodies and requires adequate penetration of antibodies into tissues. The latter is especially challenging for thick specimens, such as embryos and other whole-mount preparations. Here

    A Quantitative Assay to Measure Stress Granule Association of Proteins and Peptides in Semi-permeabilized Human Cells
    Authors:  Saskia Hutten and Dorothee Dormann, date: 12/20/2020, view: 822, Q&A: 0
    [Abstract]

    Stress granules (SGs) are membrane-less organelles that form in the cytoplasm through phase separation, in response to diverse stressors. SGs contain translationally stalled mRNAs, proteins involved in translation, and various RNA-binding proteins (RBPs). Due to the high local concentration of aggregation-prone RBPs, SGs might act as condensation

    Use of Optogenetic Amyloid-β to Monitor Protein Aggregation in Drosophila melanogaster, Danio rerio and Caenorhabditis elegans
    [Abstract]

    Alzheimer’s Disease (AD) has long been associated with accumulation of extracellular amyloid plaques (Aβ) originating from the Amyloid Precursor Protein. Plaques have, however, been discovered in healthy individuals and not all AD brains show plaques, suggesting that extracellular Aβ aggregates may play a smaller role than

    Headpost Surgery for in vivo Electrophysiological Recording in the Mouse Inferior Colliculus during Locomotion
    Authors:  Yoonsun Yang and Gunsoo Kim, date: 12/05/2020, view: 396, Q&A: 0
    [Abstract]

    The inferior colliculus (IC) is a critical midbrain integration center for auditory and non-auditory information. Although much is known about the response properties of the IC neurons to auditory stimuli, how the IC neural circuits function during movement such as locomotion remains poorly understood. Mice offer a valuable model in this respect,
