The Claim
Prior administration of the dopamine D1-like receptor antagonist SCH-23390 (10.0 μg/kg) in female rats is associated with increased overall lever responding during both extinction and cue-induced reinstatement, independent of stress exposure.
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.
In female rats, blocking dopamine D1-like receptors with SCH-23390 increases the rate of lever pressing during extinction and cue-induced reinstatement, regardless of stress exposure.
See the scientific wording
In female rats, prior administration of the dopamine D1-like receptor antagonist SCH-23390 (10.0 μg/kg) is associated with increased overall lever responding during both extinction and cue-induced reinstatement, independent of stress exposure, suggesting a sex-specific effect of D1R blockade on general motivation or behavioral activation.
Blocking a specific brain receptor in female rats removes a natural brake on behavior, causing them to press a lever more often when they see a cue that used to give food, even when the food is no longer available.
What the research says
1 studyIn female rats, blocking a specific brain receptor (D1) made them press levers more often to get food, even without being stressed. This suggests that this receptor normally acts like a brake on food-seeking behavior in females.
