The research deepens scientists' understanding of how habits like sugar and other vices manifest in the brain and suggests new strategies for breaking them.
Researchers from Duke University in US trained otherwise healthy mice to form sugar habits of varying severity, a process that entailed pressing a lever to receive tiny sweets.
Researchers compared the brains of mice that had formed a habit to the ones that did not.

In particular, the researchers studied electrical activity in the basal ganglia, a complex network of brain areas that controls motor actions and compulsive behaviours, including drug addiction.
In the basal ganglia, two main types of paths carry opposing messages - one carries a 'go' signal which spurs an action, the other a 'stop' signal.
Researchers observed that changes in go and stop activity occurred across the entire region of the basal ganglia they were studying as opposed to specific subsets of brain cells.
This might relate to the observation that an addiction to one thing can make a person more likely to engage in other unhealthy habits or addictions as well, researchers said.
The findings were published in the journal Neuron.
