Reward: this is a more complex and especially integrative form of our brain with various different elements — the external states, our internal states, how do we feel, and so on are put together. And something which maybe you don't like but you are so hungry that you really will be satisfied to eat.
Recompensa: esta es una forma más compleja y, especialmente, más integradora con varios elementos diferentes como los estados externos e internos, cómo nos sentimos, etc. Y quizá algo que no les guste pero tienen tanta hambre que realmente les satisface comer.
