Binge Eaters Dopamine Levels Spike at Sight Smell of Food

Submitted by gary on

COMMENTS: It's food, but it's a natural reinforcer, like sexual stimuli. This research demonstrates once again that binge patterns with natural reinforcers alter the reward/motivation pathways. Binge patterns in food and gambling have been shown to lower dopamine (D2) receptors. The numbed pleasure response. This leads to a craving for more dopamine stimulating stuff - sex, drugs, and rock & roll. However, this study measures sensitization of dopamine pathways. Sensitization means - an above normal release of dopamine in response to stimuli.

Impaired Decision Making Among Morbidly Obese Adults

COMMENTS: We see this as evidence that addictions to natural reinforcers (food, gambling, porn) can alter the reward circuitry. The reward circuitry has many functions, including weighing all of our decisions. Addictions are bad decisions due to a dysfunctional limbic system. Part of the rebooting process for porn users is bringing their reward circuitry back to where it was before porn. Note the problem was with weighing immediate reward against long term consequences.

Research finds source of thrill from fear (dopamine & fear)

Submitted by gary on

COMMENTS: This research shows that the reward circuitry and dopamine cell respond to fear. The same circuit that drives us with dopamine to pursue our goals, such as orgasm, is also activated by fear. This is why we "like" scary things - roller coasters, bungy-jumping, horror movies, etc. We wonder if fear or anxiety producing pornography increases the amount of dopamine released. This would make sense, because many users move into porn genres that cause anxiety and fear.

The Threatening Scent of Fertile Women

Comment: Lots of good stuff here. What's new and nicely surprising is that men in relationships find ovulating women less attractive. Single men find women more attractive around ovulation. This, and other findings here, counters the argument that pair-bonding doesn't exist in humans.

With Valentine's Day just around the corner, love is in the air. Or is it oxytocin? This so-called "love hormone" is involved in social bonding, and it always seems to get a publicity boost around Feb. 14. But research suggests that oxytocin isn't all roses and heart-shaped chocolates.
