  • Chey, Jonathan (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-05)
    An ndaptive tessellation variant of the CMAC architecture is introduced. Adaptive tessellation is an error-based scheme for distributing input representations. Simulations show that the new network outperforms the original ...
  • Chey, Jonathan; Mingnolla (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-10)
    How is the perceived direction of motion of a target affected by the motion of multiple surrounding regions? Observers viewed displays consisting of three nested regions, a circular target region surrounded by two concentric ...
  • Chey, Jonathan; Grossberg, Stephen; Mingolla, Ennio (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1995-11)
    A neural network model of visual motion perception and speed discrimination is developed to simulate data concerning the conditions under which components of moving stimuli cohere or not into a global direction of motion, ...
  • Chey, Jonathan; Grossberg, Stephen; Mingolla, Ennio (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-10)
    A neural network model of visual motion perception and speed discrimination is presented. The model shows how a distributed population code of speed tuning, that realizes a size-speed correlation, can be derived from the ...
  • Chey, Jonathan; Cisek, Paul; Gaudiano, Paolo; Wood, Richard J. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-10)
    A long-term bias in the exploratory head-waving behavior of Aplysia can be induced using bright lights as an aversive stimulus: coupling onset of the lights with head movements to one side results in a bias away from that ...
