  • A Biomechanical Model of Human Oculomotor Plant Kinematics Based Upon Geometric Algebra
    Cohen, Michael A.; Pribe, Christopher A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-06)
    A biomechanical model of the human oculomotor plant kinematics in 3-D as a function of muscle length changes is presented. It can represent a range of alternative interpretations of the data as a function of one parameter. ...
  • Frequency-Dependent Phase Transitions in the Coordination of Human Bimanual Tasks
    Cohen, Michael A.; Grossberg, Stephen; Pribe, Christopher A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)
    The 2-channel Ellias-Grossberg neural pattern generator of Cohen, Grossberg, and Pribe [1] is shown to simulate data from human bimanual coordination tasks in which anti-phase oscillations at low frequencies spontaneously ...
  • How Listing's Lay May Emerge from Neural Control of Reactive Saccades
    Pribe, Christopher A.; Bullock, Daniel (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1995-09)
    We hypothesize that Listing's Law emerges as a result of two key properties of the saccadic sensory-motor system: 1) The visual sensory apparatus has a 2-D topology and 2) motor synergists are synchronized. The theory is ...
  • Neural Control of Interlimb Oscillations II. Biped and Quadruped Gaits and Bifurications
    Pribe, Christopher A.; Grossberg, Stephen; Cohen, Michael A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-07)
    Behavioral data concerning animal and human gaits and gait transitions are simulated as emergent properties of a central pattern generator (CPG) model. The CPG model is a version of the Ellias-Grossberg oscillator. Its ...
  • A Neural Pattern Generator that Exhibits Arousal-Dependant Human Gait Transitions
    Cohen, Michael A.; Grossberg, Stephen; Pribe, Christopher A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)
    A neural pattern generator based upon a non-linear cooperative-competitive feedback neural network is presented. It can generate the two standard human gaits: the walk and the run. A scalar arousal or GO signal causes a ...
  • Quadruped Gait Transitions from a Neural Pattern Generator with Arousal Modulated Interactions
    Cohen, Michael A.; Grossberg, Stephen; Pribe, Christopher A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)
    A four-channel neural pattern generator is described in which both the frequency and the relative phase of oscillations are controlled by a scalar arousal or GO signal. The generator is used to simulate quadruped gaits; ...
