The Claim
The anteromedial subregion of the olfactory tubercle enhances hedonic responses to sucrose, while the anterolateral subregion does not enhance and may suppress hedonic responses to sucrose, demonstrating a medial-lateral gradient of hedonic modulation.
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.
Neurons in the front-medial part of the olfactory tubercle increase pleasure responses to sugar, while neurons in the front-lateral part do not increase and may reduce pleasure responses to sugar, showing a spatial pattern of hedonic processing.
See the scientific wording
The anteromedial and anterolateral subregions of the olfactory tubercle show a functional dissociation: the anteromedial region enhances hedonic responses to sucrose, while the anterolateral region does not enhance and may suppress them, indicating a medial-lateral gradient of hedonic modulation.
In the front part of the olfactory tubercle, activating neurons in the medial area reduces their inhibition of pleasure centers in the brain, making sweet tastes feel more enjoyable, while activating neurons in the lateral area does not produce this effect and may increase disgust reactions.
What the research says
1 studyIn rats, one part of a brain region makes sweet tastes feel more enjoyable, while another part makes them feel worse — like a pleasure button and a disgust button right next to each other.
