“…Muitos estudos relataram que o tamanho da cabeça influencia a amplitude e a latência das ondas (Allison et al, 1983;Trune et al, 1988;Pook e Steiss, 1990;Meij et al, 1992). No presente trabalho, não houve diferença estatística entre as características diâmetro e comprimento de cabeça entre os dois grupos; sendo assim, pode-se concluir que, apesar de se tratar de cães sem raça definida e com diferentes conformações de cabeça, essa característica não interferiu nos resultados obtidos.…”

 RESUMOO objetivo deste trabalho foi realizar estudo normativo dos potenciais evocados auditivos obtidos de 34 cães sem raça definida e avaliar a influência da idade nos resultados obtidos. Os animais foram divididos em dois grupos de diferentes faixas etárias e o potencial evocado auditivo foi realizado com um estímulo de 85dB. O grupo 1 incluiu 16 cães com idades entre um e oito anos e o grupo 2, 18 animais com idades acima de oito anos. O comprimento e o diâmetro da cabeça foram mensurados e não houve diferença estatística entre os dois grupos. No grupo 1, as médias das latências das ondas I, III e V foram: 1,13; 2,64 e 3,45ms; e dos intervalos I-III, III-V e I-V foram 1,51; 0,81 e 2,32ms, respectivamente. No grupo 2, as médias das latências das ondas I, III e V foram 1,15; 2,62 e 3,55ms; e dos intervalos I-III, III-V e I-V foram 1,47; 0,93 e 2,40ms, respectivamente. As latências observadas neste estudo foram semelhantes a estudos prévios realizados por outros autores. Nos grupos etários analisados e nas condições preestabelecidas deste estudo, a idade influenciou a latência da onda V e, consequentemente, modificou os intervalos III-V e I-V, portanto deve-se considerar essa variante na interpretação dos resultados do BAEP em cães. I, III, and V were 1.13; 2.64, and 3.45ms, 0.81, and 2.32 ms, respectively. In group 2, the mean latencies of waves I, III and V were 1.15, 2.62, and 3.55ms, 0.93, and 2.40ms, respectively. The latencies observed in this study were similar to previous studies conducted by other authors. It was observed that significant differences were present for wave V and intervals III-V and I-V latencies when comparing groups with different ages, consequently this characteristic must be considered during BAEP result interpretation.

Background: Auditory evoked potentials (AEPs) are very small electrical voltage potentials signal generated by a sound through the auditory pathway. Age and gender influence on the brainstem AEPs (BAEPs) deserve keen appraisal for correct clinical application and inference. Aims and Objective: The aims and objectives of the study are to get the normal range of latencies and amplitude of waveforms of BAEP in healthy normal person. Materials and Methods: BAEPs from either ear of normal hearing 150 men and 145 women in 1-73 years age range were studied. Absolute peak latencies of Waves I-V were examined in reference to the influence of age and gender. Result: The latencies of Waves I value are significantly higher in males in 25-34 years and 35-44 years age groups than in females. In both genders, Waves II value is higher in ≥45 years age groups. The latencies of Waves III value are significantly higher in males in all age groups except in 35-44 years age groups than in females. In males, Waves I value is higher in ≥45 years age groups while in females Waves III value is higher in 35-44 years age groups. The latencies of Waves IV value are significantly higher in males in all age groups except in 15-24 years age groups and ≥45 years age groups than in females. The latencies of Waves V value are significantly higher in males in all age groups except in 35-44 years age groups and ≥45 years age groups than in females. Conclusion: Significant changes in the BAEPs in our study support the possible role of age and gender as contributively factors for normal variations.

The brain stem auditory-evoked potential (BAEP) is an electrophysiologic test that detects and records the electrical activity in the auditory system from cochlea to midbrain, generated after an acoustic stimulus applied to the external ear. The aim of this study is to obtain normative data for BAEP in Dalmatian dogs in order to apply this to the evaluation of deafness and other neurologic disorders. BAEP were recorded from 30 Dalmatian dogs for a normative Brazilian study. Mean latencies for waves I, III, and V were 1.14 (±0.09), 2.62 (±0.10), and 3.46 (±0.14) ms, respectively. Mean inter-peak latencies for I-III, III-V, and I-V intervals were 1.48 (±0.17), 0.84 (±0.12), and 2.31 (±0.18) ms, respectively. Unilateral abnormalities were found in 16.7% of animals and bilateral deafness was seen in one dog. The normative data obtained in this paper is compatible with other published data. As far as we know this is the first report of deafness occurrence in Dalmatian dogs in Brazil.
