The image could’ve been of more glorious quality but, distressingly, the confocal microscope has been recently boned by a software ‘upgrade’. You know how it is.
- Phenylethylamine or PEA - This is an amine that naturally occurs in the brain and also in some foods, such as chocolate. It is a stimulant, much like an amphetamine, that causes the release of norepinephrine and dopamine. This chemical is found when you are falling in love. It’s responsible for the head-over-heels, elated part of love.
- Norepinephrine - When PEA causes this chemical to be released, you feel the effects in the form of sweaty palms and a pounding heart.
- Dopamine - Dopamine is a neurochemical that appears to be associated with mate selection. An Emory University study found that voles (a type of rodent) chose their mate based on dopamine release. When female voles were injected with dopamine in the presence of a male vole, they could select him from a group of voles later.
- Oxytocin - Dopamine triggers the release of oxytocin, which is sometimes called the ‘cuddle hormone’. In both genders, oxytocin is released during touching. In women, oxytocin is released during labor and breast feeding.
- Testosterone - Though you might think of testosterone as a male hormone, both men and women produce it. Raw lust is accompanied by a surge in testosterone levels.
- Endorphins - Your brain acquires a tolerance to the love stimulants and starts to release endorphins. The honeymoon is over, chemically, around 18 months to 4 years into a relationship. However, this isn’t all bad. Endorphins are associated with feelings of attachment and comfort. Endorphins are like opiates. They calm anxiety, relieve pain and reduce stress.
something i have been unable to unsee is DA’s resemblance to the noble giraffe.
Teenagers who binge drink risk inhibiting part of their brain’s development and many are laying the groundwork for alcoholism down the track a Queensland University of Technology (QUT) researcher has found.
Professor Selena Bartlett, from QUT’s Institute for Health and Biomedical Innovation (IHBI), studied the effect excessive binge drinking during adolescence had on a particular receptor in the brain and discovered teen bingeing altered it irreversibly, keeping the brain in an adolescent state.
“The human brain doesn’t fully develop until around age 25 and bingeing during adolescence modifies its circuits, preventing the brain from reaching maturity,” she said.
“During adolescence, the brain undergoes massive changes in the prefrontal cortex and areas linked to drug reward but alcohol disrupts this.
“The research, which was carried out on rats, suggests that during ageing, the brain’s delta opioid peptide receptor (DOP-R) activity turns down, but binge drinking causes the receptors to stay on, keeping it in an adolescent stage.
“The younger a child or teenager starts binge drinking and the more they drink, the worse the possible outcome for them.”
Professor Bartlett said recent trends to mix high-caffeine drinks such as Red Bull with alcohol were making the binge drinking problem worse.
…that explains somethings.
I’d like to take a second to point out that invertebrates, like most other ectotherms, are cooler than mammals.
…turns out that thanks to over exposure to poorly spelt status updates I am now hesitant to use ‘their’ or any of its homophones in case I cock it up.
coming to the end of the course. if have done approximately 116 hours of labs and lectures in the last 12 days. fairly sure i’ve also consumed close to this number in units of alcohol. also swam in chilly chilly british seas almost every day. exhaustion is my name.
