Modelo de campo neural con acci´on dual neuronal glutamat´ergica-GABA´ergica
Resumen
En este trabajo se consider´o un modelo de campo neural que modela la actividad sin´aptica media de una poblaci´on de neuronas granulares del hipocampo de tipo excitatorio e inhibitorio. A diferencia de formulaciones tradicionales se consider´o la evidencia cl´ınica observada en esta estructura cerebral en donde neuronas manifiestan una acci´on dual de tipo glutamat´ergico-GABA´ergico. Es decir, neuronas con acci´on excitatoria pueden transformar su influencia hacia tipo inhibitorio. En este trabajo se establecieron las
condiciones de existencia de patrones espacio-temporales de actividad en la forma de pulsos estacionarios, frentes y ondas viajeras en el modelo planteado. El entendimiento de las condiciones para la existencia de este tipo de soluciones es de gran importancia debido a que permite avanzar en la comprensi´on de la compleja interacci´on sin´aptica presente en la actividad cerebral.
