Insula to ventral striatal projections mediate compulsive eating produced by intermittent access to palatable food
Samantha Spierling, Giordano de Guglielmo, Dean Kirson, Alison Kreisler, Marisa Roberto, Olivier George, and Eric Zorrilla
-
The insular cortex subserves visceral-emotional functions and, based on its afferent and efferent connections, likely plays a role in the negative reinforcement so important in the compulsive intake of food and drugs characteristic of eating and substance use disorders.
-
Female rats were given intermittent access to a highly palatable diet and a subset of rats demonstrated elevated progressive ratio responding, increased punished responding and irritability following withdrawal of the diet, all suggestive of increased compulsive-like behavior.

-
Female rats were given intermittent access to a highly palatable diet and a subset of rats demonstrated elevated progressive ratio responding, increased punished responding and irritability following withdrawal of the diet, all suggestive of increased compulsive-like behavior.
-
This more compulsive-like sub-population showed decreased lever pressing upon optoinhibition of the anterior insular cortex to nucleus accumbens connection and also had a unique endocrine profile.
-
These results highlight the importance of the projections from the anterior insular cortex to the nucleus accumbens in compulsive-like behavior and support this model’s use to further study addictive disorders, such as alcohol use disorder.
