Whether we 'like' and 'want' stimuli depends partially on opioid neurotransmission within the nucleus accumbens. But how are 'liking' and 'wanting' organized within this neural substrate? Do 'liking' and 'wanting' originate from the same nucleus accumbens subregions? Or are there specific localized sites for opioid enhancement of reward 'liking' and 'liking'? The present review aims to summarize recent advances in the identification of brain substrates for food 'liking' and 'wanting' with a… CONTINUE READING
