title: [Descriptive analysis of evoked laryngeal potentials of the brainstem in rabbits].
abstract: The present study evaluated comparatively the laryngeal brainstem responses (LBR) evoked, through electrical stimulation of the superior laryngeal nerve, in 2 groups of mature rabbits, using a far field technique. Each group is formed according to the shifting of the stimulation parameters followed for the research, namely: intensity (from 0.5 to 3 mA), stimulus frequency (from 2 stimuli/second to 5 stimuli/second) and total stimulation time (between 200 microseconds to 500 microseconds). Afterwards the values attained are compared with those supplied for the control-group (having 2 mA intensity, 4 stimuli per second and 100 microseconds as time). We got significative statistical differences regarding the stimulus intensity and the outcome is a shortening in latency wawe of LBR when using 3 mA.
