    Magnetic Resonance Imaging and Histopathological Visualization of Human Dural Lymphatic Vessels
    Authors:  Seung-Kwon Ha, Govind Nair, Martina Absinta, Nicholas J. Luciano and Daniel S. Reich, date: 04/20/2018, view: 31, Q&A: 0
    In this protocol, we describe a method to visualize and map dural lymphatic vessels in-vivo using magnetic resonance imaging (MRI) and ex-vivo using histopathological techniques. While MRI protocols for routine imaging of meningeal ...
    Electrophysiological Recordings of Evoked End-Plate Potential on Murine Neuro-muscular Synapse Preparations
    Authors:  Giulia Zanetti, Samuele Negro, Aram Megighian and Marco Pirazzini, date: 04/20/2018, view: 18, Q&A: 0
    Neuromuscular junction (NMJ) is the specialized chemical synapse that mediates the transmission of the electrical impulse running along motor neuron axons to skeletal muscle fibers. NMJ is the best characterized chemical synapse and its study along ...
    Testing Effects of Chronic Chemogenetic Neuronal Stimulation on Energy Balance by Indirect Calorimetry
    Authors:  Sangho Yu and Heike Münzberg, date: 04/20/2018, view: 17, Q&A: 0
    The fundamental of neuroscience is to connect the firing of neurons to physiological and behavioral outcomes. Chemogenetics enables researchers to control the activity of a genetically defined population of neurons in vivo through the ...
    Isolation and Maintenance of Striatal Neurons
    Authors:  Luana  Naia and A. Cristina Rego, date: 04/20/2018, view: 18, Q&A: 0
    Primary cultures of murine striatal neurons are widely used to explore cellular mechanisms in neurobiology, including brain diseases. Here we describe a detailed and standardized protocol to dissect and culture embryonic murine striatal neurons ...
    Magnetic Resonance Imaging and Histopathological Visualization of Human Dural Lymphatic Vessels
    Authors:  Seung-Kwon Ha, Govind Nair, Martina Absinta, Nicholas J. Luciano and Daniel S. Reich, date: 04/20/2018, view: 31, Q&A: 0
    [Abstract] In this protocol, we describe a method to visualize and map dural lymphatic vessels in-vivo using magnetic resonance imaging (MRI) and ex-vivo using histopathological techniques. While MRI protocols for routine imaging of meningeal lymphatics include contrast-enhanced T2-FLAIR and T1-weighted black-blood imaging, a more specific ...
    Electrophysiological Recordings of Evoked End-Plate Potential on Murine Neuro-muscular Synapse Preparations
    Authors:  Giulia Zanetti, Samuele Negro, Aram Megighian and Marco Pirazzini, date: 04/20/2018, view: 18, Q&A: 0
    [Abstract] Neuromuscular junction (NMJ) is the specialized chemical synapse that mediates the transmission of the electrical impulse running along motor neuron axons to skeletal muscle fibers. NMJ is the best characterized chemical synapse and its study along many years of research has provided most of the general knowledge of synapse development, structure ...
    Testing Effects of Chronic Chemogenetic Neuronal Stimulation on Energy Balance by Indirect Calorimetry
    Authors:  Sangho Yu and Heike Münzberg, date: 04/20/2018, view: 17, Q&A: 0
    [Abstract] The fundamental of neuroscience is to connect the firing of neurons to physiological and behavioral outcomes. Chemogenetics enables researchers to control the activity of a genetically defined population of neurons in vivo through the expression of designer receptor exclusively activated by designer drug (DREADD) in specific neurons and ...
    Assessing Prepulse Inhibition of Startle in Mice
    Authors:  Christina Ioannidou, Giovanni Marsicano and Arnau Busquets-Garcia, date: 04/05/2018, view: 118, Q&A: 0
    [Abstract] Animal models are an important tool for studying neuropsychiatric disorders. However, a major challenge for researchers working with laboratory rodents is trying to reproduce ‘core’ symptoms of complex human disorders such as schizophrenia. Despite this challenge, however, it is still conceivable to use animal models designed to reproduce some of ...
    Measuring Spatiotemporal Dynamics of Odor Gradient for Small Animals by Gas Chromatography
    Authors:  Akiko Yamazoe-Umemoto, Yuishi Iwasaki and Koutarou D. Kimura, date: 04/05/2018, view: 336, Q&A: 0
    [Abstract] Odor is the most fundamental chemical stimulus that delivers information regarding food, mating partners, enemies, and danger in the surrounding environment. Research on odor response in animals is widespread, although studies on experimental systems in which the gradient of odor concentration is quantitatively measured has been quite limited. ...
    Sacral Spinal Cord Transection and Isolated Sacral Cord Preparation to Study Chronic Spinal Cord Injury in Adult Mice
    Authors:  Carmelo Bellardita, Maite Marcantoni, Peter Löw and Ole Kiehn, date: 04/05/2018, view: 122, Q&A: 0
    [Abstract] Spinal cord injury (SCI) is characterized by multiple sensory/motor impairments that arise from different underlying neural mechanisms. Linking specific sensory/motor impairments to neural mechanism is limited by a lack of direct experimental access to these neural circuits. Here, we describe an experimental model which addresses this shortcoming. ...
    Context-driven Salt Seeking Test (Rats)
    Authors:  Stephen E. Chang and Kyle S. Smith, date: 04/05/2018, view: 123, Q&A: 0
    [Abstract] Changes in reward seeking behavior often occur through incremental learning based on the difference between what is expected and what actually happens. Behavioral flexibility of this sort requires experience with rewards as better or worse than expected. However, there are some instances in which behavior can change through non-incremental ...
    Analysis of Mitochondrial Structure in the Body Wall Muscle of Caenorhabditis elegans
    Authors:  Shaarika Sarasija and Kenneth R. Norman, date: 04/05/2018, view: 162, Q&A: 0
    [Abstract] Mitochondrial function is altered in various pathologies, highlighting the crucial role mitochondria plays in maintaining cellular homeostasis. Mitochondrial structure undergoes constant fission and fusion in response to changing cellular environment. Due to this, analyzing mitochondrial structure could provide insight into the physiological state ...
    Measurement of ROS in Caenorhabditis elegans Using a Reduced Form of Fluorescein
    Authors:  Shaarika Sarasija and Kenneth R. Norman, date: 04/05/2018, view: 123, Q&A: 0
    [Abstract] Oxidative stress is implicated in the pathogenesis of various neurodegenerative diseases, including Alzheimer’s disease. Oxidative stress is a result of a disruption of the equilibrium between antioxidants and oxidants, in favor of oxidants. Since mitochondria are major sites of production and reduction of reactive oxygen species (ROS), ...
    Spared Nerve Injury Model of Neuropathic Pain in Mice
    Authors:  Joseph Cichon, Linlin Sun and Guang Yang, date: 03/20/2018, view: 274, Q&A: 0
    [Abstract] Experimental models of peripheral nerve injury have been developed to study mechanisms of neuropathic pain in living animals. The spared nerve injury (SNI) model in rodents is a partial denervation model, in which the common peroneal and tibial nerves are injured, producing consistent and reproducible tactile hypersensitivity in the skin territory ...
