    Sociability and Social Novelty Preference Tests Using a U-shaped Two-choice Field
    Authors:  Eun-Hwa Lee, Jin-Young Park, Yunjin Lee and Pyung-Lim  Han, date: 05/20/2018, view: 81, Q&A: 0
    We developed sociability tests based on use of a U-shaped two-choice field to read out behavioral states of sociability in rodents. The U-shaped two-choice field is a modified open field that is partially partitioned with a wall projecting to the ...
    Induction of Photothrombotic Stroke in the Sensorimotor Cortex of Rats and Preparation of Tissue for Analysis of Stroke Volume and Topographical Cortical Localization of Ischemic Infarct
    Authors:  Anna M. Wiersma and Ian R. Winship, date: 05/20/2018, view: 75, Q&A: 0
    The photothrombotic model of stroke is commonly used in research as it allows the ischemic infarct to be targeted to specific regions of the cortex with high reproducibility and well-defined infarct borders. Unlike other models of stroke, ...
    In vivo Use of Dextran-based Anterograde Cortical Tracers to Assess the Integrity of the Cortical Spinal Tract
    Authors:  Anna M. Wiersma and Ian R. Winship, date: 05/20/2018, view: 97, Q&A: 0
    When injected into the motor cortex of rats, anterograde tracers label fibers of the associated descending corticospinal tract (CST) that originate from pyramidal neurons in the tracer-injected cortex. These fibers can be assessed at the level of ...
    Intra-amniotic Injection of Mouse Embryos
    Authors:  Liyuan Cui, Peng Zou, Qingshuo Meng, Lu Lu and Jiayi Zhang, date: 05/20/2018, view: 58, Q&A: 0
    Recent outbreaks of infectious neuro-developmental diseases such as congenital Zika syndrome - have led to a demand for prognosis data from animal models. We developed an intra-amniotic injection mice model that allows Zika virus (ZIKV) infected ...
    Sociability and Social Novelty Preference Tests Using a U-shaped Two-choice Field
    Authors:  Eun-Hwa Lee, Jin-Young Park, Yunjin Lee and Pyung-Lim  Han, date: 05/20/2018, view: 81, Q&A: 0
    [Abstract] We developed sociability tests based on use of a U-shaped two-choice field to read out behavioral states of sociability in rodents. The U-shaped two-choice field is a modified open field that is partially partitioned with a wall projecting to the central point, resulting in two symmetrical rectangular fields, each containing closed and open square ...
    In vivo Use of Dextran-based Anterograde Cortical Tracers to Assess the Integrity of the Cortical Spinal Tract
    Authors:  Anna M. Wiersma and Ian R. Winship, date: 05/20/2018, view: 97, Q&A: 0
    [Abstract] When injected into the motor cortex of rats, anterograde tracers label fibers of the associated descending corticospinal tract (CST) that originate from pyramidal neurons in the tracer-injected cortex. These fibers can be assessed at the level of the spinal cord to determine the integrity of the descending CST and the spatial distribution of axons ...
    Induction of Photothrombotic Stroke in the Sensorimotor Cortex of Rats and Preparation of Tissue for Analysis of Stroke Volume and Topographical Cortical Localization of Ischemic Infarct
    Authors:  Anna M. Wiersma and Ian R. Winship, date: 05/20/2018, view: 75, Q&A: 0
    [Abstract] The photothrombotic model of stroke is commonly used in research as it allows the ischemic infarct to be targeted to specific regions of the cortex with high reproducibility and well-defined infarct borders. Unlike other models of stroke, photothrombosis allows the precise size and location of infarct to be tightly controlled with minimal surgical ...
    Intra-amniotic Injection of Mouse Embryos
    Authors:  Liyuan Cui, Peng Zou, Qingshuo Meng, Lu Lu and Jiayi Zhang, date: 05/20/2018, view: 58, Q&A: 0
    [Abstract] Recent outbreaks of infectious neuro-developmental diseases such as congenital Zika syndrome - have led to a demand for prognosis data from animal models. We developed an intra-amniotic injection mice model that allows Zika virus (ZIKV) infected mice to grow to puberty. In this system, ZIKV is injected into the amniotic fluid of pregnant mice and ...
    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: 383, 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: 273, 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: 206, 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: 330, 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: 539, 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: 323, 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. ...
