Pellegrino, F.C. Riquelme, L. 2007 El análisis de coherencia es la correlación que existe entre dos pares de canales EEG e informa sobre los componentes frecuenciales comunes a ellos, junto con la magnitud de su asociación. Sus elementos son: el espectro de potencia cruzada; el espectro de coherencia; y el espectro de fase. Este trabajo tiene como finalidad investigar y describir la coherencia interhemisférica en caninos adultos sanos, a efectos de definir sus patrones de normalidad. En forma adicional, hemos establecido algunas hipótesis que intentan relacionar los hallazgos con las conexiones anatómicas involucradas. Se trabajó con 24 animales sanos mayores de un año de edad. Todos los perros resultaron normales al examen físico y neurológico, y ninguno de ellos tenía antecedentes de enfermedad neurológica. Los registros electroencefalográficos fueron obtenidos con un programa diseñado para electroencefalografía computada y reconstrucción por mapeo cerebral, con 12 canales simultáneos de registro. Las variables estudiadas (coherencia por canales y por bandas electroencefalográficas) mostraron comportamientos significativamente diferentes. Los canales temporales presentan un patrón de comportamiento comprendido dentro de la banda theta, diferente al de los canales dorsales que pareciera ubicarse en la banda alpha. application/pdf 1514-6634 (impreso) 1668-3498 (en línea) coherencia cerebral interhemisférica caninos electroencefalograma cuantificado espectro de potencia cerebral interhemispheric coherence dogs quantitative electroencephalography spectral analysis spa Universidad de Buenos Aires.
