The animal came back quickly after a brief sortie which followed the second stimulation. By the time the third electrical stimulus had been applied the animal seemed indubitably to be coming back for more. first evidence for an area responsible for reward : this particular rat, milner later wrote, would advance, sniffing and searching, whenever the stimulation was turned on, and would stop or turn back when it was switched off. We don"t know the precise location of the electrode. Phenylalanine is an essential amino acid: used to create our own proteins, sometimes used to create neurotransmitters. Phenylalanine hydroxylase adds hydroxyl group to phenylalanine: obtain tyrosine, hydroxylation of phenylalanine to tyrosine occurs in the liver, hydroxyl group + phenylalanine = Th catalyzes addition of hydroxyl group to meta position of tyrosine: produces dihydroxy-l-phenylalanine (l-dopa), hydroxylation of tyrosine to l- Dopa, l-dopa to da occurs in cytosol: considered the rate-limiting step in.
