How to Create and Use Binocular Rivalry
1Department of Psychology, New York University, 2Centre for Neural Science, New York University, 3Department of Psychology, Princeton University, 4Neuroscience Institute, Princeton University
Binocular rivalry occurs when the eyes are presented with different images at the same location: one image dominates while the other is suppressed, and dominance alternates periodically. Rivalry is useful for investigating perceptual selection and visual awareness. Here we describe several easy methods for creating and using binocular rivalry stimuli.
Investigating the Neural Mechanisms of Aware and Unaware Fear Memory with fMRI
Department of Psychology, University of Alabama at Birmingham
A methodology to investigate the neural mechanisms that support aware and unaware memory processes during fear conditioning is described. This method monitors blood oxygen level dependent (BOLD) functional magnetic resonance imaging, skin conductance response, and unconditioned stimulus expectancy during Pavlovian fear conditioning to assess the neural correlates of distinct memory processes.
Acute and Chronic Tactile Sensory Testing after Spinal Cord Injury in Rats
1Center for Brain and Spinal Cord Repair, School of Allied Medical Professions, The Ohio State University, 2Spinal Cord Research Center, Drexel University College of Medicine
We describe two tactile sensory testing methods for acute or chronic periods of spinal cord injury in rats. These validated procedures can detect the development and maintenance of allodynia-like sensations.
Using Visual and Narrative Methods to Achieve Fair Process in Clinical Care
1Institute for Behavioral Health, Brandeis University, 2Heller School for Social Policy and Management, Brandeis University
This paper illustrates an innovative visual approach (photovoice or photo-elicitation) to achieve fair process in clinical care for patients living with chronic health conditions, illuminate gaps in clinical knowledge, forge better therapeutic relationships, and identify patient-centered goals and possibilities for healing.
Murine Echocardiography and Ultrasound Imaging
1Department of Pharmacology and Physiology, University of Rochester, 2Aab Cardiovascular Research Institute, University of Rochester, 3Visualsonics, 4Department of Medicine, University of Rochester
This video demonstrates use of a rail-mounted high-frequency ultrasound probe to perform echocardiography on an anesthetized mouse. The methods describe both conventional two-dimensional and M-mode measurements of cardiac function in addition to newer, more powerful tools such as color Doppler, strain analysis, as well as general and targeted contrast imaging.
Eye Tracking Young Children with Autism
1School of Behavioral and Brain Sciences, University of Texas at Dallas, 2Carolina Institute for Developmental Disabilities, School of Medicine, University of North Carolina at Chapel Hill
Eye tracking has long been used to study gaze patterns in typically-developing individuals, but recent technological advancements have made its use with clinical populations, including autism, more feasible. While eye-tracking young children with autism can offer insight into early symptom manifestations, it involves methodological challenges. Suggestions for best practices are provided.
Physiological Experimentation with the Crayfish Hindgut: A Student Laboratory Exercise
1Department of Biology, University of Kentucky, 2Department of Biological Sciences, Brock University
In this report we demonstrate techniques that can be used to investigate the biology of the crayfish hindgut. We show how to dissect a crayfish abdomen and study the associated anatomy, physiology and modulation of activity. The peristaltic activity and strength of contractions are measured using a force transducer.
Brain Imaging Investigation of the Neural Correlates of Emotion Regulation
1Department of Computing Science, University of Alberta, Edmonton, 2Department of Psychology, University of Illinois, Urbana-Champaign, 3Department of Psychiatry, University of Alberta, Edmonton, 4Department of Psychology, University of Alberta, Edmonton, 5Centre for Neuroscience, University of Alberta, Edmonton, 6Neuroscience Program, University of Illinois, Urbana-Champaign, 7Beckman Institute, University of Illinois, Urbana-Champaign
We present a protocol that allows investigation of the neural correlates of deliberate and automatic emotion regulation, using functional magnetic resonance imaging. This protocol can be used in healthy participants, both young and older, as well as in clinical patients.
Transretinal ERG Recordings from Mouse Retina: Rod and Cone Photoresponses
Department of Ophthalmology and Visual Sciences, Washington University School of Medicine
We describe a relatively simple method of transretinal electroretinogram (ERG) recordings for obtaining rod and cone photoresponses from intact mouse retina. This approach takes advantage of the block of synaptic transmission from photoreceptors to isolate their light responses and record them using field electrodes placed across the isolated flat-mounted retina.
Dissection of Human Vitreous Body Elements for Proteomic Analysis
Department of Ophthalmology and Visual Sciences, Omics Laboratory, University of Iowa
This video shows an effective technique for differentiating and dissecting the various semi-transparent structures of the human vitreous body in post mortem eyes.
