Resumen

El gusto es un sistema sensorial complejo que está vinculado a las conductas alimenticias del ser humano. Interactúa con el olfato, la sensibilidad táctil y térmica oral y hasta con la visión y la audición. Se describen actualmente cinco variedades de gusto: dulce, salado, ácido, amargo y umami. Los receptores gustatitvos se encuentran fundamentalmente en la boca. En la transducción del estímulo gustativo participan dos mecanismos: canales iónicos para los gustos salado y ácido y receptores de membrana asociados a proteìnas G para los restantes tres sabores. Se describe la vía gustativa y sus conexiones con el sistema límbico vinculadas con el placer -displacer de la degustación (hedonismo). Existen avances importantes relacionados con la codificación de los distintos estímulos gustativos, siendo la propuesta más fundamentada y aceptada la teoría de los "patrones de actividad central".Algunos reflejos gustativos se producen al servicio de la masticación, por ejemplo los reflejos gustativos salivales para la formación del bolo, gustativo motor para la modulación de la frecuencia masticatoria y gustativo facial para comia y para la expresión hedónica.
