Hedonic Hot Spots in the Brain

摘要: Hedonic "liking" for sensory pleasures is an important aspect of reward, and excessive 'liking' particular rewards might contribute to consumption disorders such as obesity. The present review aims summarize recent advances in the identification brain substrates food with a focus on opioid hot spots nucleus accumbens ventral pallidum. Drug microinjection studies have shown that opioids both areas amplify sweet taste rewards. Modern neuroscience tools Fos plume mapping further identified hedonic within pallidum, where are especially tuned magnify different structures may interact each other larger functional circuitry interconnects them. Better understanding how increase positive affective impact natural will help characterize neural mechanisms potentially involved many
