    Preparation of Cerebellum Granule Neurons from Mouse or Rat Pups and Evaluation of Clostridial Neurotoxin Activity and Their Inhibitors by Western Blot and Immunohistochemistry
    Authors:  Domenico Azarnia Tehran and Marco Pirazzini, date: 07/05/2018, view: 151, Q&A: 0
    Cerebellar Granule Neurons (CGN) from post-natal rodents have been widely used as a model to study neuronal development, physiology and pathology. CGN cultured in vitro maintain the same features displayed in vivo by mature ...
    Brain Tissue Culture of Per2::Luciferase Transgenic Mice for ex vivo Bioluminescence
    Authors:  Nora L. Salaberry and Jorge Mendoza, date: 07/05/2018, view: 138, Q&A: 0
    In circadian research, it is essential to be able to track a biological rhythm for several days with the minimum perturbation for the organisms or tissues. The use of transgenic mice lines, in which the luciferase reporter is coupled to a molecular ...

    [Abstract] Cerebellar Granule Neurons (CGN) from post-natal rodents have been widely used as a model to study neuronal development, physiology and pathology. CGN cultured in vitro maintain the same features displayed in vivo by mature cerebellar granule cells, including the development of a dense neuritic network, neuronal activity, ...
    Brain Tissue Culture of Per2::Luciferase Transgenic Mice for ex vivo Bioluminescence
    Authors:  Nora L. Salaberry and Jorge Mendoza, date: 07/05/2018, view: 138, Q&A: 0
    [Abstract] In circadian research, it is essential to be able to track a biological rhythm for several days with the minimum perturbation for the organisms or tissues. The use of transgenic mice lines, in which the luciferase reporter is coupled to a molecular clock protein (here PERIOD2), gives us the opportunity to follow the circadian activity in different ...
    Buried Food-seeking Test for the Assessment of Olfactory Detection in Mice
    [Abstract] The sense of smell allows animals to discriminate a large number of volatile environmental chemicals. Such chemical signaling modulates the behavior of several species that depend on odorant compounds to locate food, recognize territory, predators, and toxic compounds. Olfaction also plays a role in mate choice, mother-infant recognition, and ...
    Protocols to Study Declarative Memory Formation in Mice and Humans: Optogenetics and Translational Behavioral Approaches
    [Abstract] Declarative memory formation depends on the hippocampus and declines in aging. Two functions of the hippocampus, temporal binding and relational organization (Rawlins and Tsaltas, 1983; Eichenbaum et al., 1992; Cohen et al., 1997), are known to decline in aging (Leal and Yassa, 2015). However, in the literature distinct ...
    Intracellular and Mitochondrial Reactive Oxygen Species Measurement in Primary Cultured Neurons
    [Abstract] Reactive oxygen species (ROS) are chemically reactive oxygen containing molecules. ROS consist of radical oxygen species including superoxide anion (O2•−) and hydroxyl radical (•OH) and non-radical oxygen species such as hydrogen peroxide (H2O2), singlet oxygen (O2). ROS are generated by ...
    The Traveling Salesman Problem (TSP): A Spatial Navigation Task for Rats
    Author:  R. E. Blaser, date: 06/05/2018, view: 313, Q&A: 0
    [Abstract] The Traveling Salesman Problem (TSP) is a behavioral test used to measure the efficiency of spatial navigation. It is an optimization problem, in which a number of baited targets are placed in an arena, and as the subject travels between the targets, the route is recorded and compared to chance and optimal routes. The TSP is appealing for the ...
    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: 437, 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: 490, 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: 545, 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: 368, 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 ...
