    Description

    The authors measured cervical spine kinematics of patients before and after anterior cervical discectomy and fusion surgery. From the Biodynamics Laboratory website: This NIH-funded prospective study aims to identify the factors that have the greatest effect on adjacent segment mechanics after cervical fusion. A total of 88 anterior cervical fusion patients will be tested prior to surgery, and 1 and 3 years after surgery. Participants will perform full range of motion flexion/extension and rotation while biplane radiographs are collected at 30 images per second for each movement trial.

    Description

    The Molecular Biology Information Service (MBIS) of the Health Sciences Library System (HSLS) at the University of Pittsburgh conducted a 33-question Qualtrics survey in early 2018 to evaluate the effectiveness of services provided by the MBIS. The CSV file contains de-identifed survey responses--identifying information for Q6.7 was redacted. Also included is a PDF of the Qualtrics survey response report and a PDF of the survey questions (multiple choice, ranking, and free text).

  • Eye movements evoked by simultaneous stimulation of two sites in superior colliculus
    Internal Dataset

    Authors
    • Katnani, Husam
    • Gandhi, Neeraj
    Description

    The authors measured eye movements evoked by electrical stimulation delivered simultaneously to two sites in the superior colliculus of nonhuman primates. The effects of current frequency and intensity on movement trajectories are available. The data are potentially useful for understanding algorithms for decoding movement commands from population activity in the superior colliculus.

  • 3D-Printable Model: Peripheral Nerve Electrophysiology Testing Chamber
    Internal Dataset

    Alternate Title(s)
    Nerve Recording Chamber v1.0.0
    Authors
    • Horn, Charles C.
    • Farr, Laura
    • Sciullo, Michael
    Description

    This data package contains 3D printing files (in multiple formats) and instructions for producing a testing chamber.

    Peripheral nerves supply the inputs and outputs that determine how we sense and respond to both the internal and external environments; for example, the vagus detects the function of the interval organs and supplies motor output controlling the heart and gastrointestinal tract and other organs. This perfusion chamber model is designed to test evoked nerve responses using electrical stimulation of one nerve end and electrophysiological recording of the opposite nerve end (15 to 25 mm nerve length); responses can be recorded from teased fiber bundles or the whole nerve. The dissected nerve of laboratory animals, for example, musk shrew, mouse, and rat, can be placed in the middle perfusion compartment and kept alive with oxygenated Krebs solution flowing through the input port and exiting by way of the two outflow ports (2 are used to ensure that the compartment will not overflow). The lateral stimulation and recording compartments contain holes for placement of fine wire electrodes, which can be guided to the top of the model for connections to the stimulator and recording equipment (e.g., high impedance head stage and amplifier system). The lateral compartments are sealed from the middle perfusion compartment by running the nerve under thin plastic gates coated with vacuum grease; gates are lowered into grooves that are built into the model.

  • 3D-Printable Model: Stomach-Vagus Electrophysiology Testing Chamber with Mechanical Stimulus Placement Grid v1.0.0
    Internal Dataset

    Description

    This data package contains 3D printing files (in multiple formats) and instructions for producing a testing chamber.

    The gastric vagus supplies critical information to the brain for the control of feeding and aversive signaling, such as nausea and vomiting. This perfusion chamber model (with a grid for testing mechanical stimuli) is designed to test mechanical or chemical stimuli applied to the stomach while recording electrophysiological responses from the vagus, from teased fiber bundles or the whole nerve. The dissected stomach, with attached vagus, of small laboratory animals, including musk shrew (a vomiting species) and mouse (a non-vomiting species), can be placed in the perfusion (stomach) compartment and kept alive with oxygenated Krebs solution flowing through the input port and exiting through the two outflow ports (2 are used to ensure that the compartment will not overflow). The included detachable grid allows the experimenter to record the placement of a mechanical probe in alphanumeric coordinates; Von Frey filaments (e.g., 10 mg force) can to used to apply mechanical stimulation. The recording compartment contains holes for placement of fine wire electrodes, which can be guided to the top of the model for connections to recording equipment (e.g., high impedance head stage and amplifier system). The two compartments are sealed by running the nerve connected to the stomach under a plastic gate, coated with vacuum grease; the gate is lowered into grooves that are part of the model. Based on this model, it is possible to produce a testing chamber for a larger species, such as the laboratory rat, by extending the size of the stomach compartment.
