"Liking"
Berridge is known for his work on brain systems for pleasure (“liking”). Using an assay for “liking” called Taste Reactivity Analysis developed by taste researchers, Berridge measures facial palatability responses to tastes, which are similar between rodents, primates and humans. When something enjoyably sweet is tasted, characteristic licking responses occur. When something aversively bitter is tasted, gaping and head shaking occur. Berridge has helped identify brain 'hedonic hotspots,' such as the nucleus accumbens and ventral pallidum, where opioid, endocannabinoid, and GABA neurotransmission coordinate the “liking” of tastes. Berridge postulates that these hedonic hotspots may be crucial for how the brain produces the hedonic pleasurable feelings common to delicious food, sex, drugs, and other rewards (a role previously thought to be played mostly by brain dopamine systems).

Famous quotes containing the word liking:
“Good discipline is more than just punishing or laying down the law. It is liking children and letting them see that they are liked. It is caring enough about them to provide good, clear rules for their protection.”
—Jeannette W. Galambos (20th century)
“Liking one person is an extra reason for liking another.”
—E.M. (Edward Morgan)
“My father is one of the few men I know who say they do not like Shakespeare. He says “Shakespeare is so very coarse.” I could forgive my father for not liking Shakespeare if it was only because Shakespeare wrote poetry, but this is not the reason. He says he likes Tennyson and this gravely aggravates his offence.”
—Samuel Butler (1835–1902)
