Cerebellar speech representation: lesion topography in dysarthria as derived from cerebellar ischemia and functional magnetic resonance imaging.
BACKGROUND Lesion topography and the pathophysiological background of dysarthria due to focal cerebellar lesions have not yet been fully clarified. OBJECTIVES To investigate the lesion topography of dysarthria due to cerebellar ischemia and evaluate brainstem functions. DESIGN Case studies. PATIENTS Eighteen right-handed patients with sudden-onset dysarthria and cerebellar ischemia with a...
متن کاملSpeech Representation and Speech Understanding
The core objective of the research is to encode speech into segments which retain necessary information for accurate continuous speech recognition, but are more efficient to deal with than the usual encoding of short fxames of speech. We use a multi-stage decision-tree encoder with linear combinations of features at the decision nodes; the result is segments which cover multiple frames and whic...
متن کاملSpeech disorders in cerebellar disease.
The areas of cerebellar damage most commonly associated with dysarthria were sought by reviewing the clinical, radiographic, surgical, and autopsy findings in patients with nondegenerative cerebellar disease. Case histories on 162 patients with focal cerebellar lesions were reviewed. All but 15 of the patients underwent surgery, and 28 had autopsies. Thirty-one of the 122 patients with adequate...
متن کاملBilateral representation in the deep cerebellar nuclei.
The cerebellum is normally assumed to represent ipsilateral movements. We tested this by making microelectrode penetrations into the deep cerebellar nuclei (mainly nucleus interpositus) of monkeys trained to perform a reach and grasp task with either hand. Following weak single electrical stimuli, many sites produced clear bilateral facilitation of multiple forelimb muscles. The short onset lat...
متن کاملCategorical speech perception in cerebellar disorders.
Keele and Ivry (1991) considered the cerebellum an "internal clock" responsible for temporal computations both in the motor and in the perceptual domain. These authors, therefore, expected that the processing of durational parameters of the perceived acoustic speech signal such as voice onset time (VOT) depends upon the cerebellum as well. However, a preliminary investigation of Ivry and Gopal ...
