Addiction profoundly alters motivational circuits so that drugs become powerful reinforcers of behavior. The interoceptive system continuously updates homeostatic and emotional information that are important elements in motivational decisions. We tested the idea that interoceptive information is essential in drug craving and in the behavioral signs of malaise. We inactivated the primary interoceptive cortex in amphetamine-experienced rats, which prevented the urge to seek amphetamine in a place… 

Inactivation of the insular cortex increases anxiety-like behavior in rats : relevance to drug abuse and interoception

Anxiety-like effects detected after insular manipulation in each of the three behavioral paradigms indicate that the insula plays an important role in the interoceptive circuit responsible for coordinating the integration of external and internal stimuli as a means to generate behavior responses appropriate to the current state of the body.

The role of the insular cortex in naloxone-induced conditioned place aversion in morphine-dependent mice.

The findings indicate that the integrity of the insular cortex is essential to motivational aversion associated with morphine withdrawal, and that this kind of aversion induces neuroadaptation, observed as the increase of FosB/deltaFosB expression, in the INSULAR cortex.


Data support involvement of the interoceptive insular cortex in mediating responsiveness to ethanol in alcohol-experienced animals and indicate significant levels of ethanol intake and preference during the chronic exposure phase led to heightened chemosensory cue reactivity to ethanol.

Interoception and alcohol addiction: Vagotomy induces long‐lasting suppression of relapse‐type behavior

Even though vagotomy completely eliminates the effect of alcohol deprivation, it has no impact on water consumption or animal weight, which gives valuable information about the relationship between the autonomic nervous system and alcohol use disorders and allows for new clinical research that might have translational options.

Activation of visceral insular cortex in response to ethanol sensory cues after prolonged ethanol exposure

Differences in ethanol cue-elicited activation of the visceral insular cortex in subjects with and without a history of chronic ethanol exposure are examined, suggesting the insula may play an important role in processing of novelty/prior experience of ethanol-related stimuli.

Effects of inactivating the agranular or granular insular cortex on the acquisition of the morphine-induced conditioned place preference and naloxone-precipitated conditioned place aversion in rats

The data suggest that the insular cortex is involved in positive and negative affective learning related to opiate addiction, and that the GI appears to be critical for both forms of Affective learning, whereas the AI is crucial for learning associated with negative affects induced by opiate withdrawal.

The hidden island of addiction: the insula

Anterior insula stimulation suppresses appetitive behavior while inducing forebrain activation in alcohol-preferring rats

The results show the critical role of the anterior insula in regulating reward-directed behavior and delineate an insula-centered functional network associated with the effects of insula stimulation and suggest that potentiation ofinsula excitability with neuromodulatory methods, such as repetitive transcranial magnetic stimulation (rTMS), could be useful in the treatment of alcohol use disorders.

Insular hypocretin transmission regulates nicotine reward

It is demonstrated that insular hypocretin transmission plays a permissive role in the motivational properties of nicotine, and therefore may be a key neurobiological substrate necessary for maintaining tobacco addiction in human smokers.

The role of interoception in addiction: A critical review




Neural systems of reinforcement for drug addiction: from actions to habits to compulsion

It is hypothesized that the change from voluntary drug use to more habitual and compulsive drug use represents a transition at the neural level from prefrontal cortical to striatal control over drug seeking and drug taking behavior as well as a progression from ventral to more dorsal domains of the striatum, involving its dopaminergic innervation.

Behavioral Regulation of the Milieu Interne in Man and Rat

This specialized conditioning mechanism, which specifically adjusts gustatory hedonic values through delayed visceral feedback, is widespread among animals, including man and rat, and is based on the animals' having similar gustatory systems, similar convergence of gustatory and internal afferents to the nucleus solitarius, and similar midbrain regulatory mechanisms.

Addiction motivation reformulated: an affective processing model of negative reinforcement.

A reformulation of the negative reinforcement model of drug addiction is offered and it is proposed that the escape and avoidance of negative affect is the prepotent motive for addictive drug use.

Rewarding and Psychomotor Stimulant Effects of Endomorphin-1: Anteroposterior Differences within the Ventral Tegmental Area and Lack of Effect in Nucleus Accumbens

It is found that rats would learn without priming or response shaping to lever-press for microinjections of EM-1 into the ventral tegmental area (VTA); responding was most vigorous for high-dose injections into the posterior VTA.

A role for lateral hypothalamic orexin neurons in reward seeking

It is shown that activation of lateral hypothalamus orexin neurons is strongly linked to preferences for cues associated with drug and food reward and reinstates an extinguished drug-seeking behaviour.

Damage to the Insula Disrupts Addiction to Cigarette Smoking

It is found that smokers with brain damage involving the insula, a region implicated in conscious urges, were more likely to undergo a disruption of smoking addiction, characterized by the ability to quit smoking easily, immediately, without relapse, and without persistence of the urge to smoke.
