Dopamine takes a hit: how neuroscience is rethinking the 'feel-good' chemical

Dopamine is one of the most extensively studied neurotransmitters, chemicals that convey signals from cell to cell. It's the one with the highest profile outside neuroscience: often known as the 'pleasure chemical', it's depicted as the hit of reward that people get from recreational drugs or scrolling through social media. That's a gross simplification of what dopamine does; on that, researchers agree.

Incredible map reveals how the brain processes different emotions

They created an artificial 'mental map', with pleasantness along one axis and bodily reactions along the other, and charted how the brain responded while watching clips from films. The results revealed clear groupings in the way that our brains represent emotion - with guilt, anger and disgust in one corner and happiness, satisfaction and pride in the other.

Neuroscience reveals that people who feel trapped in repetitive daily routines aren't lazy or unmotivated. Their dopamine system has downregulated to match the predictability, which means the routine didn't kill their motivation - it quietly rewired their brain to stop expecting anything worth anticipating. - Silicon Canals

Overly predictable routines suppress dopamine and motivation by eliminating the uncertainty that drives anticipation, causing emotional numbness despite external life satisfaction.

Talking About Nerve!

I received an email recently that claims Wal-Mart senior management has been calling mandatory meetings for the company's employees in which the employees are told they "cannot" vote for the Obama-Biden ticket "or any other employee-friendly, union-friendly candidates for political office". It's not an urban legend, according to the sources I checked. This makes me so angry I just boil. When it comes to the Constitution, I am a rabid supporter.

Could Glial Cells Be the Key to New Schizophrenia Treatments?

Anyone living with schizophrenia understands the true limitations of current treatment options. Antipsychotics remain the single leading treatment for the disorder, and they are riddled with undesirable side effects. Weight gain, tardive dyskinesia, and excessive drowsiness are a few. Much research is devoted to expanding the range of medication options, and few academics have pursued other avenues. However, there is a possibility that treatment for schizophrenia can be approached through cellular methods if long-term research validates early signs of hope.

Scientists Say Go Ahead, Keep Gooning

Adult content has never been as accessible as it is now, thanks to the internet. Hell, online smut played a major role in the rise of the web itself in the 1990s. With that glut of porn, some have voiced concerns that some people are consuming too much of the stuff or even becoming addicted, which they claim could have consequences like regulating emotions or impaired sexual functioning.

How hesitation is a fundamental brain feature, according to neuroscientists

At the Winter Olympics, skiers, bobsledders, speedskaters, and many other athletes all have to master one critical moment: when to start. That split second is paramount during competition because when everyone is strong and skilled, a moment of hesitation can separate gold from silver. A competitor who hesitates too much will be left behind -but moving too early will get them disqualified.

Are Frontal Lobe Breakups Real?

There are lots of reasons why relationships fall apart; all kinds of incompatibilities can doom romance. Some are trivial, but occasionally there might be something more profound at the root of an estrangement. Recently, the concept of the "frontal lobe breakup" appeared in popular culture. The idea is that the final stage of development in the executive regions of the brain-the frontal lobes-changes someone's perspective about their relationship. The onset of advanced cognitive skills in one partner creates a gap in maturity too big to bridge.

The Adolescent Brain and Delinquency

Adolescence is second only to early childhood in the rapidity and sheer volume of changes occurring in brain development. Three different brain systems (and their interconnections) are at play: reward-driven behavior, harm avoidance, and regulatory behavior. At the same time, teens are experiencing powerful changes to their physical and sexual selves, accompanied by the hormonal cascade of puberty. During this period, there is an increase in brain receptors for dopamine, a neurotransmitter that has a strong effect on the experience of pleasure.
