This Video Explains How Stress Breaks Down Your Brain

If you think there’s a possibility of Alzheimer’s for you, please make sure you make plans with regard to health, etc. before things get bad and you can’t make those decisions anymore. Things easily become a big mess in those situations.

Maternal Testosterone Exposure Increases Offspring’s Anxiety

Women with polycystic ovary syndrome (PCOS) have elevated levels of testosterone and its chemical relatives. They also have an increased risk of anxiety and depression. Both sons and daughters of women with PCOS have similar symptoms, so it might be transmitted through traditional genetic means. But the idea is gaining traction that it is the fetal environment—specifically, the fact that the fetuses of mothers with PCOS are gestating in high levels of testosterone—that’s associated with the problems.

Sadly, no news on how to alleviate the issue.  Just that we’ve confirmed a link.

How a Human Scream Uniquely Activates the Fear Response in Your Brain

We know human screams are jarring. They’re loud, occasionally shrill, and tend to make us feel stressed, or even fearful. What’s unclear is why they elicit anxiety. But a new study suggests this response may have something to do with the acoustic quality of human screams, and how they trigger the brain’s fear response.

It’s a sound/frequency we do not experience in normal, everyday settings.

I remember a friend remarking about knowing the difference when her kids would scream, to tell when things were really bad or they were faking.  Another instance I remember was someone telling me about knowing when they were hearing a “death rattle”, in rural areas where a given animal got injured bad enough.  We communicate a lot through sound – say one thing, but our tone infers another.

Individual Neurons Tell Us Whether We Remember Something

It’s hard to pin down exactly what makes us remember things. When you see an image, what makes you decide you’ve seen it before? A new study has tackled this question, identifying a group of neurons that participate in the process of identifying images as familiar.

What about those who have eidetic memory?  This will have to wait for further study.

Yes, There’s A Masculine Side To Estrogen

Male aggression is commonly pinned on testosterone, and estrogen is credited with imparting females with maternal instinct – but the true story of the sex hormones, and their roles in male and female behavior, is a lot more subtle. Here’s why estrogen is an important hormone for males and females alike.

…Using model organisms, biologists have learned some surprising things about the relationship between testosterone, estrogen, and sexually dimorphic behaviors, and wholly debunked the facile notion that testosterone drives male behavior, while estrogen drives female behavior.

Baldness is not a sign of virility, aggression or libido. All it means is that the hair follicles in the scalp are more sensitive to testosterone. It says nothing about overall testosterone levels or how that hormone is being used elsewhere in the body.

What Caused These Men to Eat Cats and Candles?

Charles Domery was a Polish man whose eating habits astounded three armies. Tarrare was a Frenchman who went from carnival act to spy to suspected murderer. What made these men so desperately hungry?

I knew brothers in high school, both with the same insane metabolism.  Their mother would pack unbelievable amounts of food for their lunch.  I don’t remember if they were fast at eating it, but they were both around 6 feet tall and struggled to weigh more than 100 lbs.

I’ve lost contact with those two, but I’ve been encountering similar people in later stages of life.  Such people are now dealing with high blood pressure in their mid-30’s, among other medical issues.  It comes back to how we as a culture see body fat as an indicator of health.  It is to a reasonable extent, but it isn’t the entire picture.
