The Claim
Microinjection of DAMGO into the anteromedial olfactory tubercle of rats increases Fos expression in the caudal ventral pallidum and rostromedial orbitofrontal cortex.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Injecting DAMGO into a specific brain region in rats increases activity in distant brain areas known to process pleasure.
See the scientific wording
DAMGO microinjection into the anteromedial olfactory tubercle of rats increases Fos expression in distant hedonic hotspots including the caudal ventral pallidum and rostromedial orbitofrontal cortex, suggesting functional coordination within a distributed neural network for pleasure.
Activating a specific brain region with a chemical that binds to mu-opioid receptors turns off a group of inhibitory neurons, which releases a chain of other brain areas that process pleasure, causing them to become active together and amplify the feeling of liking sweet tastes.
What the research says
1 studyScientists injected a chemical into a specific part of rats' brains and found that it turned on activity in two other brain areas known to be involved in feeling pleasure — showing these areas work together like a team to create happy feelings.
