ABSTRACT

Our brains learn because we make associations supported by functional neural connectivities. For us to survive in the terms of Evolution, when we spy a suitable source of water or food, it is beneficial to remember its whereabouts. When we stagger upon something threatening, it is advantageous to remember this as well. And this learning system of reward and reinforcement, that is to be found in organisms with the most primitive nervous system structures such as planaria or the simple flatworm, in its most elemental form has three elements: a trigger, behavior and reward. We see grapes, we consume them, and if they taste good (reward), we build a memory trace to return for more.
