Measuring Sensitivity to Viewpoint Change with and without Stereoscopic Cues

1Research School of Psychology, Australian National University, 2School of Psychology, University of Western Australia, 3McGill Vision Research, Department of Ophthalmology, McGill University

JoVE 50877

We discuss a novel method forviewpoint-rotation of visual stimuli, and demonstrate using a mirror stereoscopethe three-dimensional percept of rotation-in-depth. The technique can be used to investigate the role of stereoscopic cues in encoding viewpoint-rotated figures.

Permeabilization of Adhered Cells Using an Inert Gas Jet

1Chemical Engineering, McGill University, 2Montreal Heart Institute

JoVE 50612

This protocol describes a method for the temporary permeabilization of adherent cells using an inert gas jet. This technique facilitates the transfer of genetic material and biomolecules into adherent mammalian cells by the utilization of mechanical forces to disrupt the plasma membrane.

How to Detect Amygdala Activity with Magnetoencephalography using Source Imaging

1Department of Psychology, University of Wisconsin-Milwaukee, 2McConnell Brain Imaging Centre, Montreal Neurological Institute, McGill University, 3Department of Neurology, Medical College of Wisconsin

JoVE 50212

This article describes how to record amygdala activity with magnetoencephalography (MEG). In addition this article will describe how to conduct trace fear conditioning without awareness, a task that activates the amygdala. It will cover 3 topics: 1) Designing a trace conditioning paradigm using backward masking to manipulate awareness. 2) Recording brain activity during the task using magnetoencephalography. 3) Using source imaging to recover signal from subcortical structures.

Evaluation of Respiratory System Mechanics in Mice using the Forced Oscillation Technique

1Meakins-Christie Laboratories, Department of Medicine, McGill University, 2SCIREQ Scientific Respiratory Equipment Inc.

JoVE 50172

The present protocol provides a detailed step-by-step description of the procedures required to execute measurements of respiratory system mechanics as well as the assessment of airway responsiveness to inhaled methacholine in mice using the forced oscillation technique (flexiVent; SCIREQ Inc, Montreal, Qc, Canada).

Recording and Analysis of Circadian Rhythms in Running-wheel Activity in Rodents

1Douglas Mental Health University Institute, Department of Psychiatry, McGill University, 2Center for Studies in Behavioral Neurobiology, Department of Psychology, Concordia University

JoVE 50186

Circadian rhythms in voluntary wheel-running activity in mammals are tightly coupled to the molecular oscillations of a master clock in the brain. As such, these daily rhythms in behavior can be used to study the influence of genetic, pharmacological, and environmental factors on the functioning of this circadian clock.

The Measurement and Treatment of Suppression in Amblyopia

1Department of Optometry and Vision Science, University of Auckland, 2Department of Ophthalmology, McGill University, 3Centre for Intelligent Machines, McGill University

JoVE 3927

Amblyopia is a developmental disorder of the visual cortex that is often accompanied by strong suppression of one eye. We present a new technique for measuring and treating interocular suppression in patients with amblyopia that can be deployed using virtual reality goggles or a portable iPod Touch device.

Methods for Intravenous Self Administration in a Mouse Model

1Addictions Unit, McGill University Health Centre

JoVE 3739

The intravenous self-administration (IVSA) paradigm is considered to be the gold standard in examining the reinforcing properties of drugs of abuse in rodents. This manuscript outlines the experimental procedures and surgical techniques necessary to obtain reliable IVSA data. In particular, meticulous catheter implantation and maintenance are highlighted.

Mapping the After-effects of Theta Burst Stimulation on the Human Auditory Cortex with Functional Imaging

1Montreal Neurological Institute and International laboratory for Brain, Music, and Sound (BRAMS), McGill University

JoVE 3985

Auditory processing is the basis of speech and music-related processing. Transcranial Magnetic Stimulation (TMS) has been used successfully to study cognitive, sensory and motor systems but has rarely been applied to audition. Here we investigated TMS combined with functional Magnetic Resonance Imaging to understand the functional organization of auditory cortex.

Solubilization and Bio-conjugation of Quantum Dots and Bacterial Toxicity Assays by Growth Curve and Plate Count

1Department of Biomedical Engineering, McGill University, Montreal, QC Canada

JoVE 3969

Nanoparticles such as semiconductor quantum dots (QDs) can be used to create photoactivatable agents for anti-microbial or anti-cancer applications. This technique shows how to water-solubilize cadmium telluride (CdTe) QDs, conjugate them to an antibiotic, and perform a bacterial inhibition assay based upon growth curves and plate count.

Detection of Viral RNA by Fluorescence in situ Hybridization (FISH)

1Lady Davis Institute for Medical Research, Sir Mortimer B. Davis Jewish General Hospital, 2Department of Microbiology and Immunology, McGill University, 3Department of Medicine, Division of Experimental Medicine, McGill University

JoVE 4002

A fluorescence in situ hybridization (FISH) method was developed to visually detect viral genomic RNA using fluorescence microscopy. A probe is made with specificity to the viral RNA that can then be identified using a combination of hybridization and immunofluorescence techniques. This technique offers the advantage of identifying the localization of the viral RNA or DNA at steady-state, providing information on the control of intracellular virus trafficking events.

Cannulation of the Mouse Submandibular Salivary Gland via the Wharton's Duct

1Faculty of Dentistry, McGill University, 2National Institutes of Health, Bethesda, MD, USA

JoVE 3074

A protocol for the cannulation of the mouse submandibular salivary gland via the Wharton's duct is described. For this experiment, the trypan blue solution is used as a dyer to demonstrate how this technique effectively delivers infusions into the targeted gland, and to suggest the reliability of this new approach as a potential clinical drug/cell therapy for the regeneration of salivary glands.

Collecting Variable-concentration Isothermal Titration Calorimetry Datasets in Order to Determine Binding Mechanisms

1Department of Chemistry, McGill University

JoVE 2529

ITC is a powerful tool for studying the binding of a ligand to its host. In complex systems however, several models may fit the data equally well. The method described here provides a means to elucidate the appropriate binding model for complex systems and extract the corresponding thermodynamic parameters.

The Microfluidic Probe: Operation and Use for Localized Surface Processing

1Department of Biomedical Engineering, McGill University

JoVE 1418

In this video we present the microfluidic probe1 (MFP). We explain in detail how to assemble the MFP, mount it atop an inverted microscope, and align it relative to the substrate surface, and finally show how to use it to process a substrate surface immersed in a buffer solution.
