  53. Chaos in Human Phonation and Its Measurement
    Jack Jiang; Fiscal Year: 2007
    ..The sensitivity and specificity of nonlinear dynamic parameters in distinguishing normal from pathologic voices will be assessed based on the received operating characteristic (ROC) analysis. [unreadable] [unreadable]..
  54. Spatial Auditory Plasticity
    Barbara Shinn Cunningham; Fiscal Year: 2007

  55. COMBINATIONS OF MASKING AND SENSORINEURAL HEARING LOSS
    Walt Jesteadt; Fiscal Year: 2001
    ..Hearing loss and masking are clearly not equivalent. Learning more about precisely how they differ will lead to a better understanding of both processes and of how they interact with one another. ..

  57. CRCNS: Innovative technologies inspired by biosonar
    Cynthia Moss; Fiscal Year: 2007
    ..It will also lay the foundation for a wide range of biomedical applications, such as implantable neural prostheses, ultra-lightweight low power sensors, controllers, medical tool design, and sonar-based assistive medical devices. ..
  58. Hemispheric Lateralization for Audiovocal Communication
    STUART WASHINGTON; Fiscal Year: 2007
    ..For these experiments, I will pair electrical stimulation of the right side with call stimuli and test if the application of BMI at the recording site on the left side reverses this effect. ..
  59. PERIPHERAL INTERACTIONS IN AUDITORY TEMPORAL PROCESSING
    ANDREW OXENHAM; Fiscal Year: 2008

  60. Androgen modulation of vocal neurons
    Ayako Yamaguchi; Fiscal Year: 2009
    ..This more detailed understanding of cellular activity is necessary for further progress to be made in developing therapeutic approaches to epilepsy. ..
  61. CENTRAL MECHANISMS RELATED TO TINNITUS
    JAMES KALTENBACH; Fiscal Year: 2007
    ..Our focus will be on channels which have a strong influence on the level of spontaneous activity and which have been found in other systems to be up- or down-regulated following loss of afferent input. ..
  62. Randomized Trial of Tinnitus Retraining Therapy
    Richard Tyler; Fiscal Year: 2008
    ..If TRT is shown to be no more effective than masking or counseling, professionals should focus on more efficient therapeutic techniques. This experiment will test the neurophysiological model of tinnitus. [unreadable] [unreadable]..
