These sensory and mental inputs converge on the hypothalamus, which relays signals to the medulla oblongata. Vagus nerve fibres from the medulla stimulate the parasympathetic nervous system of the stomach which, in turn, stimulates gastric secretion.

So the answers are Cerebrum, Hypothalamus, and Medulla oblongata.
