    A Modified Barnes Maze for Juvenile Rats
    Authors:  Nazanin Valibeigi, Daniel G. McHail, Carmen L. Kimball and Theodore C. Dumas, date: 11/20/2018, view: 1228, Q&A: 0
    [Abstract] To better understand neural codes for spatial navigation and to address cognitive development questions, the neurobiology of postnatal hippocampal development is receiving increased attention. While the Morris Water Maze is the gold standard for assessing hippocampal integrity, potential confounds can be difficult to control for in juvenile ...
    6-hydroxydopamine (6-OHDA) Oxidative Stress Assay for Observing Dopaminergic Neuron Loss in Caenorhabditis elegans
    Authors:  Sarah-Lena Offenburger and Anton Gartner, date: 09/20/2018, view: 1315, Q&A: 0
    [Abstract] The nematode Caenorhabditis elegans is a powerful genetic model that can be used to investigate neuronal death. Research using C. elegans has been crucial to characterize cell death programmes that are conserved in mammals. Many neuronal signaling components, such as those mediating dopaminergic neurotransmission, are preserved ...
    Organotypic Explants of the Embryonic Rodent Hippocampus: An Accessible System for Transgenesis
    Authors:  Archana Iyer , Lakshmi Subramanian and Shubha Tole, date: 03/20/2018, view: 2178, Q&A: 0
    [Abstract] This protocol describes the technique of ex-vivo electroporation to target embryonic hippocampal progenitors in an organotypic slice preparation. This technique allows gene perturbation for examining developmental processes in the embryonic hippocampus while retaining the environment and connectivity of the cells. Gene perturbation can ...
    Mandibular Explant Assay for Investigating Extrinsic Stimuli on Bone and Cartilage Development
    Authors:  Jamie Jiang, Jessica W. Bertol and Walid D. Fakhouri, date: 12/05/2017, view: 3011, Q&A: 0
    [Abstract] A major issue in developmental biology is to determine how embryonic tissues respond to molecular signals in a timely manner and given the position-restricted instructions during morphogenesis, of which Meckel’s cartilage is a classical example. The ex-vivo explant model is a practical and convenient system that allows investigation of ...
    FM1-43 Photoconversion and Electron Microscopy Analysis at the Drosophila Neuromuscular Junction
    Authors:  Nadezhda S. Sabeva and Maria Bykhovskaia, date: 09/05/2017, view: 3692, Q&A: 0
    [Abstract] We developed a protocol for photoconversion of endocytic marker FM1-43 followed by electron microscopy analysis of synaptic boutons at the Drosophila neuromuscular junction. This protocol allows detection of stained synaptic vesicle even when release rates are very low, such as during the spontaneous release mode. The preparations are ...
    Microinjection of Virus into Lumbar Enlargement of Spinal Dorsal Horn in Mice
    Authors:  Zhi-Jun Zhang, Peng-Bo Jing and Yong-Jing Gao, date: 11/20/2016, view: 7293, Q&A: 0
    [Abstract] In order to explore the role of a specific gene/protein in the specific segment of the spinal cord, the technique of intraspinal injection is particularly used to deliver viral vectors targeting the specific gene/protein. These viral vectors can knockdown or overexpress the specific gene/protein in specific cells (glial cells or neurons). In this ...
    In utero Electroporation of Mouse Cerebellar Purkinje Cells
    Author:  Yukari H. Takeo, date: 06/05/2016, view: 8238, Q&A: 0
    [Abstract] In utero electroporation (IUE) of mouse cerebellar Purkinje cells allows high expression levels of transgenes without toxicity (Nishiyama et al., 2012). This technique is suitable for co-transfection of multiple plasmid genes. Therefore, it is useful to express various sets of genes such as drug-inducible Cre/loxP constructs and ...
    Dissection and Staining of Mouse Brain Ventricular Wall for the Analysis of Ependymal Cell Cilia Organization
    [Abstract] In the developing and mature central nervous system (CNS) the ventricular lumen is lined by the neuroepithelium and ependymal, respectively. These ventricular epithelia perform important functions related to the development, morphogenesis and physiology of the brain. In the mature CNS, ependyma constitutes a barrier between brain parenchyma and ...
    Fluoro-Jade B Staining for Neuronal Cell Death
    Authors:  Nathalie Laflamme, Paul Préfontaine and Serge Rivest, date: 01/05/2016, view: 11818, Q&A: 2
    [Abstract] Fluoro-Jade is a fluorescent derivative used for histological staining of degenerating neurons. This technique is simple and sensitive enough to label distal dendrites, axons, axon terminals as well as neuronal bodies. Fluoro-Jade has excitation and emission peak of 480 and 525 nanometer respectively. It can be visualized using a fluorescein/FITC ...
    Chick Neural Tube Explant Culture
    Authors:  Zhanna Alekseenko, Elisabet Andersson and José M. Dias, date: 10/05/2015, view: 6024, Q&A: 0
    [Abstract] The neural tube explant culture technique allows in vitro culturing of small pieces of neural tissue isolated from e.g., chick or mouse embryonic tissue in a matrix of collagen for defined periods of time. This method can be used to study the effects of defined molecules on developmental processes such as neural progenitor ...
