Babies Make Dads Change

Some researches have been asking a simple question that has led to complex insights: what changes does the male body go through when they have a child? Indeed, there are some physical changes like producing less testosterone and more oxycontin, but it’s what goes on in the mind where researchers are finding the complexity. The fathers with lower testosterone spent more time with their children and the more time that fathers spent with their infants the lower their testosterone became. Fathers experience mental changes during their partner’s pregnancy and even men who just spend a lot of time with babies experience mental changes too.

Saxbe has been investigating whether the consequences of these hormonal shifts leave their marks on dads’ brains. “I thought fathers are actually a very interesting, almost a special population in the sense that they experience the transformations of parenthood without biological pregnancy,” she told me.

In Father Time, she argues that as humans evolved into more complex societies, it was collective care that made humans flourish. It was valuable to have men that could provide primary care for a baby, and so we developed a capacity to do so – one we still keep.

mRNA Vaccine Used to Fight Brain Tumour

Brain tumours are scary and very difficult to deal with, current treatments include invasive surgery and/or radiation. The advent of mRNA based vaccines is making a difference in how we can treat various brain cancers and the early results are looking promising. A team just found a way to get the body’s immune system to start to find and address cancer within the brain. While the results are not yet usable the outlook is very promising.

“The demonstration that making an mRNA cancer vaccine in this fashion generates similar and strong responses across mice, pet dogs that have developed cancer spontaneously and human patients with brain cancer is a really important finding, because oftentimes we don’t know how well the preclinical studies in animals are going to translate into similar responses in patients,” said Duane Mitchell, M.D., Ph.D., director of the UF Clinical and Translational Science Institute and the UF Brain Tumor Immunotherapy Program and a co-author of the paper. “And while mRNA vaccines and therapeutics are certainly a hot topic since the COVID pandemic, this is a novel and unique way of delivering the mRNA to generate these really significant and rapid immune responses that we’re seeing across animals and humans.”

Practicing Meditation Changes Your Brain and Sense of Self

hands

Achieving mindfulness through mediation can help you relax and even assist you in achieving a more fulfilling life. Recent fMRI studies have shown that this can be proven by looking at the brain itself; indeed, structures inside your brain tend to alter based on how much meditation one does! This is really neat stuff because it means you can change the way you think and process the world through a very simple practice!

What should the average person take away from your study?

Mindful self-awareness is a non-judgemental, present-moment awareness of body and contents of the mind. On the neural level, this form of awareness quietens regions related to inner speech, ​thinking about the self, and ruminating, while regions related to the perception of the body are activated. In our study we found that the neural pattern during mindful self and body awareness was stronger in less depressed, healthier individuals. Thus, mindful self-awareness seems to represent a particularly healthy mode of self-perception.

We also found – as expected – that neural activations related to mindful self-awareness were particularly strong in expert mindfulness meditators. More interestingly, we also show that when we instruct untrained participants to enter relatively short periods of mindful self-awareness in the MRI scanner, these patterns can also be seen in untrained participants.

This means, meditation training increases the ability to perceive the self in a more healthy, present-moment, body-centered way, but also that already in untrained individuals, short periods of mindful self-awareness are possible and offer the potential to enter a healthy self-perception state.​

The Science Behind How Nature Changes Your Brain

Talking a walk amongst plants is good for you in many ways, but why? This questions recently bothered some neuroscientists and they set out to answer it. It turns out that exposure to nature changes the way blood flows in our brain in a way that makes us feel better.

Then the scientists randomly assigned half of the volunteers to walk for 90 minutes through a leafy, quiet, parklike portion of the Stanford campus or next to a loud, hectic, multi-lane highway in Palo Alto. The volunteers were not allowed to have companions or listen to music. They were allowed to walk at their own pace.

Immediately after completing their walks, the volunteers returned to the lab and repeated both the questionnaire and the brain scan.

As might have been expected, walking along the highway had not soothed people’s minds. Blood flow to their subgenual prefrontal cortex was still high and their broodiness scores were unchanged.

But the volunteers who had strolled along the quiet, tree-lined paths showed slight but meaningful improvements in their mental health, according to their scores on the questionnaire. They were not dwelling on the negative aspects of their lives as much as they had been before the walk.

Travel For a Better Brain

I just booked a flight to London and coincidentally came across an article that says that our brains can benefit greatly from exploring the world. A good way to start the day!

It turns out that the ability of the brain to handle new information is connected to well-being and that travel can get your bring working in new ways. It is also beneficial to step out of your comfort zone, which travelling general encourages. So you should book that trip you’ve been thinking about!

In recent years, psychologists and neuroscientists have begun examining more closely what many people have already learned anecdotally: that spending time abroad may have the potential to affect mental change. In general, creativity is related to neuroplasticity, or how the brain is wired. Neural pathways are influenced by environment and habit, meaning they’re also sensitive to change: New sounds, smells, language, tastes, sensations, and sights spark different synapses in the brain and may have the potential to revitalize the mind.

“Foreign experiences increase both cognitive flexibility and depth and integrativeness of thought, the ability to make deep connections between disparate forms,” says Adam Galinsky, a professor at Columbia Business School and the author of numerous studies on the connection between creativity and international travel. Cognitive flexibility is the mind’s ability to jump between different ideas, a key component of creativity. But it’s not just about being abroad, Galinsky says: “The key, critical process is multicultural engagement, immersion, and adaptation. Someone who lives abroad and doesn’t engage with the local culture will likely get less of a creative boost than someone who travels abroad and really engages in the local environment.” In other words, going to Cancun for a week on spring break probably won’t make a person any more creative. But going to Cancun and living with local fishermen might.
