This study demonstrates that the cortical language network is affected differently by the left and right temporal lobe epilepsy and is reorganized after anterior temporal lobectomy.
This study relates over time the changes in voluntary opening and closing of the vocal folds (vocal fold diadochokinesis, or VFDDK) of patients with amyotrophic lateral sclerosis (ALS). The rate, pattern, and periodicity of VFDDK were examined for 12 ALS subjects with bulbar and 14 subjects with nonbulbar signs of the disease. The acoustical data were analyzed with a commercially available computer-based speech analysis system. ALS patients with bulbar and nonbulbar symptoms demonstrate reduced rate and aperiodic VFDDK as the symptomatology of the neuromotor system progresses. Individuals with bulbar signs show a greater change in vocal fold activity than do the nonbulbar group. Discussion of the clinical implications for initial diagnosis and monitoring of changes over time in motor control of laryngeal function is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
