Dissecting the Non-human Primate Brain in Stereotaxic Space
1Department of Physiology, University of Montreal, 2School of Optometry, University of Montreal, 3Département de chimie-biologie , Université du Québes à Trois-Rivières
The non-human primate is an important translational species for our understanding of the normal processing of the brain. The anatomical organization of the primate brain can provide important insights into normal and pathological conditions in humans.
A Rapid Approach to High-Resolution Fluorescence Imaging in Semi-Thick Brain Slices
1Department of Molecular & Human Genetics, Baylor College of Medicine (BCM), 2Precisionary Instruments Inc., 3Departments of Molecular & Human Genetics and Neuroscience, Baylor College of Medicine (BCM), 4Jan and Dan Duncan Neurological Research Institute, Texas Children's Hospital
Here we describe a rapid and simple method to image fluorescently labeled cells in semi-thick brain slices. By fixing, slicing, and optically clearing brain tissue we describe how standard epifluorescent or confocal imaging can be used to visualize individual cells and neuronal networks within intact nervous tissue.
Cerebrovascular Casting of the Adult Mouse for 3D Imaging and Morphological Analysis
1Center for Cerebrovascular Research, Department of Anesthesia and Perioperative Care, University of California, San Francisco, 2Department of Neurological Surgery, University of California, San Francisco, 3Department of Neurology, University of California, San Francisco
In this article, we present a simple, practical technique for cerebrovascular casting that is easy to perform and can be utilized to image the vascular tree of the adult mouse brain.
Dual Somatic Recordings from Gonadotropin-Releasing Hormone (GnRH) Neurons Identified by Green Fluorescent Protein (GFP) in Hypothalamic Slices
Department of Biology, University of Texas San Antonio - UTSA
Activity in neuronal systems often requires synchronous action potential discharges from neurons within a specific population. For example, pulses of gonadotropin-releasing hormone (GnRH) likely require coordinated activity between GnRH neurons. We present our methodological approach for reliably obtaining simultaneous electrophysiological recordings from the diffusely distributed GnRH neurons.
Specimen Preparation, Imaging, and Analysis Protocols for Knife-edge Scanning Microscopy
1Department of Computer Science and Engineering, Texas A&M University, 2Beckman Institute for Advanced Science and Technology, University of Illinois, 3Department of Electrical and Computer Engineering, Kettering University, 43Scan, 5Department of Veterinary Integrative Biosciences, Texas A&M University
The full process from brain specimen preparation to serial sectioning imaging using the Knife-Edge Scanning Microscope, to data visualization and analysis is described. This technique is currently used to acquire mouse brain data, but it is applicable to other organs, other species.
Batch Immunostaining for Large-Scale Protein Detection in the Whole Monkey Brain
1Cognitive Neuroscience Unit, Montreal Neurological Institute, 2Ècole d’Optomètrie, Universitè de Montrèal, 3Department of Psychology, McGill University
Large-scale immunodetection of target proteins across the entire primate brain is possible by employing novel tissue embedding and sectioning methods combined with the use of creative apparatus for batch staining of multiple free-floating sections at a given time.
Primary Neuronal Cultures from the Brains of Late Stage Drosophila Pupae
Department of Development and Cell Biology, Department of Anatomy and Neurobiology, University of California, Irvine (UCI)
This video demonstrates the preparation of primary neuronal cultures from the brains of late stage Drosophila pupae. Views of live cultures show neurite outgrowth and imaging of calcium levels using Fura-2.
Non-Laser Capture Microscopy Approach for the Microdissection of Discrete Mouse Brain Regions for Total RNA Isolation and Downstream Next-Generation Sequencing and Gene Expression Profiling
Center for Sleep and Circadian Biology, Northwestern University
RNA expression profiling of discrete mouse brain regions requires a precise and repeatable tissue collection strategy. A protocol that uses both coronal brain sectioning and tissue corer-assisted microdissection is described here. The yield and quality of total RNA obtained from the resulting samples confirms the utility of the outlined method.
Preparation of Developing and Adult Drosophila Brains and Retinae for Live Imaging
Department of Physiology and Green Center for Systems Biology, University of Texas Southwestern Medical Center
This protocol describes three Drosophila preparations: 1) adult brain dissection, 2) adult retina dissection and 3) developing eye disc- brain complexes dissection. Emphasis is laid on special preparation techniques and conditions for live imaging, although all preparations can be used for fixed tissue immunohistochemistry.
Live Imaging of Glial Cell Migration in the Drosophila Eye Imaginal Disc
Department of Zoology, University of British Columbia - UBC
Here we describe a protocol to examine the migration of glial cells into the developing Drosophila eye using live microscopic analysis paired with GFP tagged glial cells.
