Long-latency auditory evoked potentials with verbal and nonverbal stimuli.
INTRODUCTION Long-latency auditory evoked potentials represent the cortical activity related to attention, memory, and auditory discrimination skills. Acoustic signal processing occurs differently between verbal and nonverbal stimuli, influencing the latency and amplitude patterns. OBJECTIVE To describe the latencies of the cortical potentials P1, N1, P2, N2, and P3, as well as P3 amplitude, ...
متن کاملTemporal processing and long-latency auditory evoked potential in stutterers.
INTRODUCTION Stuttering is a speech fluency disorder, and may be associated with neuroaudiological factors linked to central auditory processing, including changes in auditory processing skills and temporal resolution. OBJECTIVE To characterize the temporal processing and long-latency auditory evoked potential in stutterers and to compare them with non-stutterers. METHODS The study included...
متن کاملLong Latency Auditory Evoked Potential in Term and Premature Infants
Introduction The research in long latency auditory evokes potentials (LLAEP) in newborns is recent because of the cortical structure maturation, but studies note that these potentials may be evidenced at this age and could be considered as indicators of cognitive development. Purpose To research the exogenous potentials in term and premature infants during their first month of life. Materials a...
متن کاملP300-long-latency auditory evoked potential in normal hearing subjects: simultaneous recording value in Fz and Cz.
UNLABELLED The P300 is and auditory Evoked Potential, called endogenous potential because it reflects the functional use the individual makes of the auditory stimulus, being highly dependent on cognitive skills; among them we list attention and auditory discrimination. It is a procedure of objective evaluation; however, one that depends on the examiner's experience to detect wave peaks, and it ...
متن کاملTest-Retest of Long Latency Auditory Evoked Potentials (P300) with Pure Tone and Speech Stimuli
Introduction Long latency auditory evoked potentials, especially P300, have been used for clinical evaluation of mental processing. Many factors can interfere with Auditory Evoked Potential - P300 results, suggesting large intra and inter-subject variations. Objective The objective of the study was to identify the reliability of P3 components (latency and amplitude) over 4-6 weeks and the most ...
