Like many scientists around the world, researchers working out of UC San Diego have high hopes for how our brainwaves might one day be used to control devices, tackle neurological disorders and everything in between. Any drug targeting the basal ganglia with the purpose of altering habits might prove challenging to create given the complexity of this region of the brain, the Duke researchers admit.Īrticle Cite Source: Premium reusable Gold Cup EEG Electrodes with 10mm cup diameter from Greentek The Pavlok developers also encourage replacing bad habits with good ones to bolster success.Īnyone hoping to avoid magnets or shock treatments, instead preferring to pop a pill, may be disappointed. Its creators told Reuters last year that the shock is meant to disrupt the neural patterns that form the bad habits, discouraging their repetition in the future. Last year, one Boston start-up, called Pavlok, unveiled their own solution to breaking bad habits: a wristband that shocks the user any time he or she tries to engage in a designated self-destructive action. Knowing the influence of addictive, self-destructive behaviors on brain circuitry could lead to treatments to break them, such as transcranial magnetic stimulation, or using harmless magnetic pulses to stimulate the brain, an avenue some researchers have already begun exploring. The head start given to the go pathway could explain difficulties in self control for those working to correct compulsive behaviors.Įncouraged by the researchers, some mice were able to break the habit when the scientists rewarded only the rodents who stopped pressing the lever, though the mice most able to do this were the ones with the weaker go pathways. The opposite pattern emerged in the other test group. For the mice that formed the habit, the go pathway lit up before stop. The timing of the activation of these pathways differed in the two groups as well. Two pathways in the basal ganglia carry separate, opposing messages, “stop” and “go.”įor the mice who formed a sugar dependency, the researchers were surprised to find both the “stop” and “go” signals ramped up in the brain compared with ordinary mice. Within the brain is an area known as the basal ganglia, which is responsible for motor action and compulsive behaviors. After the sweets were taken away, the sugar-addicted mice continued pressing the lever even without the reward.

The rodents developed the habit by pressing a small lever to receive a sugary treat. The greater the change in the brain circuitry, the more difficult it is to kick a habit.įor their study, published today in the journal Neuron, the Duke scientists analyzed the brains of mice who developed a sugar dependency and compared those with otherwise healthy mice. Bad habits are hard to break, but why is that?Īccording to new research by Duke University researchers, our vices are hard-wired in a region of brain responsible for compulsive behavior and addiction, leaving an enduring mark that pushes us to succumb to our cravings. Everyone has some kind of self-destructive behavior we’d be better off without, be it smoking or an unhealthy diet. Three weeks into 2016 and many resolutions are as stale as a bottle of champagne left open after a New Year’s party. If you do stay together you can thank the hormones oxytocin and vasopressin, which when released can make you feel more attached and committed to your partner. That’s why people can also fall out of love after a few months. It’s no wonder star-crossed lovers are willing to die for each other! In fact, the love drive is stronger than the sex drive! Love is addictive but like drugs, the love high becomes less strong over time.

The part of the brain that lights up with cocaine addiction, also lights up with love. Ever found yourself thinking about your love interest 24/7? That’s due to serotonin.Īnd when we fall in love, dopamine gets released and makes you crave your love interest. It’s responsible for infatuation and excitement. The heart racing, butterflies in your stomach, palms sweating early dating phase is due to norepinephrine. Dopamine, the feel-good, can’t-get-enough, neurotransmitter gets released during the initial ‘I met someone, ooh you’re kinda cute’ stage. Love or loath it? Whatever your feelings are, they come from your brain and not your heart! That’s right, when you are attracted to someone it’s really driven by chemicals in your brain!Īt first, the sex chemicals testosterone and estrogen kick off what we call “lust” for someone.Ī trifecta of brain chemicals affect your mood: dopamine, serotonin and norepinephrine.
