The Disney ad elicited strong responses in orbito-frontal cortex and ventral striatum, two brain regions associated with processing of rewards.
These genetic variations affect the brain's regulation of dopamine, the neurotransmitter associated with the processing of rewards and new stimuli (and drugs like cocaine).
This is significant because that part of the brain has been shown, by other studies, to be involved in the processing of rewards.Pathological gamblers, Dr Dymond and his team discovered, display similar increases in theta activity in the right orbitofrontal cortex whether they win or "nearly win": spikes of about 32% and 27% respectively in the strengths of their theta waves.
The processing of rewards is basal for operant conditioning.
Clinical studies, too, focused on the processing of rewards, mostly money, after OFC lesions [37], [38], [39] and did not consider an elementary faculty like reality filtering.
Third, apart from initial processing of rewards or punishments, impaired integration of reward-punishment information in regions that decide on future behaviors could cause excessive risky behavior; e.g., under risky conditions substance-dependent adults under-recruit specialized conflict-monitoring circuitry in posterior mesofrontal cortex [21]; also see [22], [23].

It is not surprising that there has been a growing interest within cognitive neuroscience on how executive or cognitive control processes might interact with motivational states and the processing of reward information.
In summary, we report the first preliminary evidence of circadian variation in the neural processing of reward.
Results substantiate dysfunctional OFC activity at a very early stage in the processing of reward stimuli in patients with OCD.
In rodents, there is abundant evidence for the involvement of the opioid system in the processing of reward cues, but this system has remained understudied in humans.
A handful of functional neuroimaging studies suggest that systematic diurnal variation exists in brain activity related to other functions, but no published human studies have examined daily variation in the neural processing of reward.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
