Using MazeSuite and Functional Near Infrared Spectroscopy to Study Learning in Spatial Navigation
1School of Biomedical Engineering, Science and Health Systems, Drexel University, 2College of Nursing and Health Professions, Drexel University
MazeSuite is a complete toolset to prepare, present and analyze navigational and spatial experiments. Functional near-infrared spectroscopy (fNIR) is an optical brain imaging technique that enables noninvasive and portable monitoring of cerebral blood oxygenation changes. This paper summarizes collective use of MazeSuite and fNIR within a cognitive processing learning paradigm.
A Video Demonstration of Preserved Piloting by Scent Tracking but Impaired Dead Reckoning After Fimbria-Fornix Lesions in the Rat
Department of Neuroscience, Canadian Centre for Behavioural Neuroscience, University of Lethbridge
In a piloting scent tracking task, the ability of the rats to return to a refuge with food using visual an odor trail or using dead reckoning in infrared light, the integrated record of previous movements, demonstrates that the hippocampus is necessary for dead reckoning.
Design and Construction of a Cost Effective Headstage for Simultaneous Neural Stimulation and Recording in the Water Maze
Department of Neuroscience, Friedman Brain Institute, Mount Sinai School of Medicine
We present a low-cost method to design and construct a light headstage pre-amplifier system with simultaneous neural recording and stimulation capability. This device can be waterproofed for use in swimming animals.
Functional Mapping with Simultaneous MEG and EEG
Athinoula A. Martinos Center for Biomedical Imaging, MGH - Massachusetts General Hospital
We use magnetoencephalography (MEG) and electroencephalography (EEG) to map brain areas involved in the processing of simple sensory stimuli.
Low-stress Route Learning Using the Lashley III Maze in Mice
1Department of Chemistry, Pennsylvania State University, 2Center for Developmental and Health Genetics, Pennsylvania State University, 3Department of Veterinary and Biomedical Sciences, Pennsylvania State University, 4Huck Institute of the Life Sciences, Pennsylvania State University, 5California NanoSystems Institute, University of California, Los Angeles, 6Semel Institute of Neuroscience and Human Behavior, University of California, Los Angeles
The Lashley III maze is a route-learning task that does not rely on aversive stimuli or visual cues. It is thus a highly attractive option for evaluating learning and memory, especially in aging mice or otherwise where stress is a consideration.
MPI CyberMotion Simulator: Implementation of a Novel Motion Simulator to Investigate Multisensory Path Integration in Three Dimensions
1Department of Human Perception, Cognition and Action, Max Planck Institute for Biological Cybernetics, 2Laboratoire de Physiologie de la Perception et de l'Action, Collège de France - CNRS, 3Department of Brain and Cognitive Engineering, Korea University
An efficient way to gain insight into how humans navigate themselves in three dimensions is described. The method takes advantage of a motion simulator capable of moving observers in ways unattainable by traditional simulators. Results confirm that movement in the horizontal plane is underestimated, while vertical movement is overestimated.
Intra-Operative Behavioral Tasks in Awake Humans Undergoing Deep Brain Stimulation Surgery
1Nayef Al-Rodhan Laboratories for Cellular Neurosurgery and Neurosurgical Technology, Harvard Medical School, 2Department of Neurosurgery , Massachusetts General Hospital
Deep brain stimulation surgery offers a unique opportunity to examine information encoding in the awake human brain. This article will describe intra-operative methods used to perform cognitive and behavioral tasks while simultaneously acquiring physiological data such as EMG, single-unit neuronal activity and/or local field potentials.
Microvascular Decompression: Salient Surgical Principles and Technical Nuances
1Department of Neurosurgery, Vanderbilt University Medical Center, 2Vanderbilt School of Medicine, Vanderbilt University Medical Center
There are many available options for management of the patient with trigeminal neuralgia. Microvascular decompression, while the most invasive of all options, is also the most effective at achieving long term remission of symptoms. Video instruction on how to maximize efficacy and minimize complications with this procedure is described.
Organotypic Hippocampal Slice Cultures
Department of Physiology and Biophysics, University of Washington School of Medicine
We describe a method to prepare organotypic hippocampal slices that can be easily adapted to other brain regions. Brain slices are laid on porous membranes and culture media is allowed to form an interface. This method preserves the gross architecture of the hippocampus for up to 2 weeks in culture.
Cercarial Transformation and in vitro Cultivation of Schistosoma mansoni Schistosomules
Department of Biology, Case Western Reserve University
We describe an in vitro method for culturing schistosomula of the flatworm parasite Schistosoma mansoni, via the harvesting and transformation of infective cercariae from the fresh water snail intermediate host Biomphalaria glabrata.
