Men who worry that women may not make the right decisions during a menstrual cycle, and women who claim biology is a valid excuse for being a jerk, you're both out of luck.
An examination of three aspects of cognition across two menstrual cycles found that the levels of estrogen, progesterone and testosterone had no impact on working memory, cognitive bias or ability to pay attention to two things at once.
While some hormones were associated with changes across one cycle in some of the women taking part, these effects didn't repeat in the following cycle. Overall, none of the hormones the team studied had any replicable, consistent effect on study participants' cognition.
Many have advanced the idea that adolescent anatomical brain development justifies denying adolescents the civil liberties and decisional autonomy that are granted to almost all adults automatically . In an earlier writing, I made a case for the opposite position
, pointing out that a significant fraction of the adult population never exceeds the behavioral maturity of a typical 13-year-old, therefore an age of majority above 13 is equivalent to declaring a lot of normal adults to be incompetent.
Capacity for vicarious experiences is a fundamental aspect of human social behavior. For example, seeing others experiencing pain can activate brain circuits that are known to support actual first-hand experience of pain.
A new study has revealed how the human brain’s opioid system modulates responses to other people’s pain. The less opioid receptors the participants had in their brain, the stronger were their emotion and pain circuits’ response to seeing others in distress. Similar association was not found for the dopamine system despite its known importance in pain management.
The effects of a "bug" in the analysis of functional neuroimages (AFNI) software was greatly exaggerated, a finding that is in defiance of numerous other studies which have found that false positive rates in the analysis of functional magnetic resonance imaging (fMRI) of the brain may negate the findings of countless previous studies.
Neurological and psychiatric conditions both involve the brain, but are treated very differently. Put simply, neurologists are trained to deal with the “brain” and psychiatrists to deal with the “mind”. Neurologists and psychiatrists formally parted company in the late 19th century.
Ever since the days of Sigmund Freud – who was originally a neurologist but is also the father of psychoanalysis – the way we think about brain disorders has been coloured by this artificial divide.
Some people have an extreme fear of spiders or other objects while others have breathing difficulties and accelerated heart beat in small rooms or large gatherings of people. Some anxiety attacks occur for no apparent cause. Some patients suffer from the detrimental impacts on their everyday lives, they have problems at work and withdraw from social contacts.
A new fMRI study used neural activity in 80 people to accurately predict the virality of 80 New York Times health articles.
Well, it's the New York Times, a top five newspaper in the U.S. so the results are going to be skewed by that, as were the articles selected; the public loves weak observational claims about health and the demographic that reads the New York Times is most inclined to believe claims about miracle vegetables, scary chemicals and diet fads.
Though scant progress has been made in treating or understanding Alzheimer's disease in the last 100 years, one thing is known; there are declines in glucose levels in the hippocampus early on. What has remained unclear is whether that is a cause or consequence.
A new analysis finds that youths who hold off on trying marijuana until age 17 do better on cognitive tests and drop out of school at a lower rate than those who start by age 14. Obviously negative health behavior in alcohol and cigarettes are linked in the same ways, but those two have not gotten the health halo that marijuana has gotten, thanks to politicians who have turned a blind eye to health concerns in the interest of generating more revenue.
In the first installment
of this two-part post, I mentioned that from my perspective I had understood
Kaepernick had a right to protest as an American, but all of that sentiment had
changed through a series of interlocking events. Here is what I mean by the interlocking
events. There is curious coming together of a few topics from current events
that is taking place now.
