  • Hampson, Michelle; Guenther, Frank; Cohen, Michael (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-11)
    The McGurk effect has generally been studied within a limited range of phonetic contexts. With the goal of characterizing the McGurk effect through a wider range of contexts, a parametric investigation across three different ...
  • Tourville, Jason; Guenther, Frank (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2003-11)
    A neuroanatomical parcellation system is described which encompasses the entire cerebral cortex and the cerebellum. The cortical system modified version of the scheme described by Caviness et al. (1996) and is designed ...
  • Husaine, Fatima; Negishi, Michiro; Cohen, Michael; Guenther, Frank (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-10)
    A number of models of single language vowel classification based on formant representations have been proposed. We propose a new model that explicitly predicts vowel perception by second language (L2) learners based on the ...
  • Guenther, Frank; Ghosh, Satrajit; Tourville, Jason (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2004-08)
    This paper describes a neural model of speech acquisition and production that accounts for a wide range of acoustic, kinematic, and neuroimaging data concerning the control of speech movements. The model is a neural network ...
  • Guenther, Frank; Bullock, Daniel (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1992-11)
  • Greve, Douglas; Grossberg, Stephen; Guenther, Frank; Bullock, Daniel (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1992-02)
    This article describes how corollary discharges from outflow eye movement commands can be transformed by two stages of opponent neural processing into a head-centered representation of 3-D target position. This representation ...
  • Grossberg, Stephen; Guenther, Frank; Bullock, Daniel; Greve, Douglas (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1992-02)
    A neural network model is described for how an invariant head-centered representation of 3-D target position can be autonomously learned by the brain in real time. Once learned, such a target representation may be used to ...
  • Guenther, Frank; Nieto-Castanon, Alfonso; Ghosh, Satrajit; Tourville, Jason (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2002-09)
    We used functional magnetic resonance imaging (fMRI) to investigate the representation of sound categories in human auditory cortex. Experiment 1 investigated the representation of prototypical and non-prototypical examples ...
  • Nieto-Castanon, Alfonso; Ghosh, Satrajit; Tourville, Jason; Guenther, Frank (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2002-09)
    In this technical report, we present fMRI analysis techniques that test functional hypotheses at the region of interest (ROI) level. An SPM-compatible Matlab toolbox has been developed which allows the creation of ...
  • Bullock, Daniel; Grossberg, Stephen; Guenther, Frank (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1992-02)
    A neural network is introduced which provides a solution of the classical motor equivalence problem, whereby many different joint configurations of a redundant manipulator can all be used to realize a desired trajectory ...
  • Guenther, Frank (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-04)
    This article describes a neural network model of speech motor skill acquisition and speech production that explains a wide range of data on contextual variability, motor equivalence, coarticulation, and speaking rate ...
  • Guenther, Frank; Hampson, Michelle; Johnson, Dave (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1997-02)
    Does the speech motor control system utilize invariant vocal tract shape targets of any kind when producing phonemes? We present a four-part theoretical treatment favoring models whose only invariant targets are auditory ...
