Psy-World

	Selected videos from JoVE Journal of Visualized Experiments
Journal of Visualized Experiments (JoVE) (http://www.jove.com) is a peer reviewed, online journal devoted to the publication of biological research in a video format. JoVE uses video technology to capture and transmit the life science research thus facilitating the understanding and efficient reproduction of experimental techniques. The journal is listed in PubMed and can be cited as any peer reviewed publication. Psy-world will periodically feature videos of potential interest to psychiatrists and neuroscientists wishing to understand better the techniques that provide the data they are used to hearing.
Selected video publications
NEW Measurement of Neuromagnetic Brain Function in Pre-school Children with Custom Sized MEG Graciela Tesan, Blake W. Johnson, Melanie Reid, Rosalind Thornton, Stephen Crain, Macquarie Centre for Cognitive Science, Macquarie University, Australia
Play the video subscription required	The advent of MEG systems sized for young children opens important new opportunities to study brain development. The new system, together with a protocol that aligns experimental requirements with the capacities of children, can be used to study cognitive and language processes in healthy, awake children aged three to six. Published 19 February 2010
Elevated Plus Maze for Mice Munekazu Komada, Keizo Takao, Tsuyoshi Miyakawa Kyoto University Graduate School of Medicine and the Fujita Health University, Japan
Play the video	The elevated plus maze test is one of the most widely used tests for measuring anxiety-like behavior in mice. This video shows the detailed procedures for conducting the test. Published 22 December 2008
Functional Imaging with Reinforcement, Eyetracking, and Physiological Monitoring Vincent Ferrera, Jack Grinband, Tobias Teichert, Franco Pestilli, Stephen Dashnaw, Joy Hirsch Columbia University, New York, USA
Play the video	This presentation demonstrates the use of fMRI to study neural circuits that underlie decision-making. Simple perceptual tasks are combined with appetitive and aversive reinforcements to investigate how outcomes affect decision processes. Published 13 November 2008
Morris Water Maze Experiment Joseph Nunez Department of Psychology, Michigan State University
Play the video	The Morris water maze is widely used to study spatial memory and learning. Animals are placed in a pool of opaque water where they must swim to a submerged platform. Since the animals cannot see the platform, they must rely on external/extra-maze cues. As the animals become more familiar with the task, they are able to find the platform more quickly. Developed by Richard G. Morris in 1984, this paradigm has become one of the "gold standards" of behavioral neuroscience. Published 24 September 2008
Survivable Stereotaxic Surgery in Rodents Brenda M. Geiger, Lauren E. Frank, Angela D. Caldera-Siu, Emmanuel N. Pothos Department of Pharmacology and Experimental Therapeutics, Tufts University School of Medicine
Play the video	The monitoring of extracellular neurotransmitter levels in distinct brain regions of freely moving animals offers insights on the link between neurotransmitter release and behavior. In vivo microdialysis coupled with electrochemical detection provides excellent anatomical and chemical resolution; and information on how basal neurotransmission is altered by pharmacological or physiological manipulations. This video shows how microdialysis probes are emplanted. Published 10 June 2008
Neuronal Nuclei Isolation from Human Postmortem Brain Tissue Anouch Matevossian, Schahram Akbarian Psychiatry, Brudnick Neuropsychiatric Research Institute, University of Massachusetts Medical School
Play the video	The cellular heterogeneity of brain tissue poses a significant limitation for the study of epigenetic markings in chromatin because most assays lack single cell resolution. Neurons typically are intermingled with glia and other non-neuronal cells. We provide a protocol to extract and collect neuronal nuclei from human brain. Published 10 January 2008
