A limited study of parental transmission of anxiety/stress-reactive traits

This 2016 New York rodent study found: “Parental behavioural traits can be transmitted by non-genetic mechanisms to the offspring. We show that four anxiety/stress-reactive traits are transmitted via independent iterative-somatic and gametic epigenetic mechanisms across multiple generations. As the individual traits/pathways each have their own generation-dependent penetrance and gender specificity, the resulting cumulative phenotype is … Continue reading A limited study of parental transmission of anxiety/stress-reactive traits

Brain-region-specific energy metabolism affected the social competitiveness of highly-anxious rats

This 2015 Swiss rodent study found: “Mitochondrial function in the nucleus accumbens, a brain region relevant for motivation and depression, is a critical mediating factor in the subordinate status displayed by high-anxious rats. Treatment with nicotinamide, an amide form of vitamin B3 that boosts mitochondrial respiration, into the NAc [nucleus accumbens] of high-anxious rats at … Continue reading Brain-region-specific energy metabolism affected the social competitiveness of highly-anxious rats

Fetal exposure to sex hormones and female anxiety

This 2015 Swedish rodent study found: “Women with polycystic ovary syndrome (PCOS) display high circulating androgen levels that may affect the fetus and increase the risk of mood disorders in offspring. Although clinical data are inconsistent, there are indications that androgens play a crucial role in behavior and mood regulation in females. Studies on the … Continue reading Fetal exposure to sex hormones and female anxiety

Leaky gates, anxiety, and grocery store trips without buying list items

An interview with Jeff Link, the editor of Dr. Arthur Janov’s 2011 book “Life Before Birth: The Hidden Script that Rules Our Lives” with Ken Rose: “Even further confirmation for some of the views of Janov, that maybe weren’t widely accepted for a time, it’s new research now being done into memory and what a … Continue reading Leaky gates, anxiety, and grocery store trips without buying list items

Are a child’s genes the causes for their anxiety?

This 2015 Wisconsin macaque study was another attempt to justify the school’s continuing captivity of thousands of monkeys. The researchers performed a study that – if its experimental design was truly informative for helping humans – could have been done with humans. A problem I saw in the news coverage was that the finding of: … Continue reading Are a child’s genes the causes for their anxiety?

We feel anxious even when making a choice from multiple good options

This 2014 Harvard/Princeton research studied brain areas as people made choices among multiple good options: “Our results show that choice conflict can at least lead to substantial short-term anxiety, that this anxiety increases with the number and value of one’s options (potentially enhanced by time pressure), and that it is not attenuated by awareness of … Continue reading We feel anxious even when making a choice from multiple good options

Do delusions have therapeutic value?

This 2019 UK review discussed delusions, aka false beliefs about reality: “Delusions are characterized by their behavioral manifestations and defined as irrational beliefs that compromise good functioning. In this overview paper, we ask whether delusions can be adaptive notwithstanding their negative features. We consider different types of delusions and different ways in which they can … Continue reading Do delusions have therapeutic value?

Fear of feeling?

Here’s a 2018 article from two researchers involved in the Dunedin (New Zealand) Longitudinal Study. They coauthored many studies, including People had the same personalities at age 26 that they had at age 3. The paper’s grand hypothesis was: “A single dimension is able to measure a person’s liability to mental disorder, comorbidity among disorders, … Continue reading Fear of feeling?

Unindexed comment links?

It’s dawned on me that although links in blog posts are indexed by search engines, links in comments may not be. Here’s a post to elevate links in three comments that may have escaped notice. From A review of biological variability: “It is my view that all researchers have a narrow focus on what they … Continue reading Unindexed comment links?

Group statistics don’t necessarily describe an individual

I’m curating this 2018 UC Berkeley/Drexel/Netherlands analysis of human studies via its press coverage. The authors: “Collaborated to analyze data on hundreds of adults – some mentally or physically sound, others suffering from various conditions such as depression, anxiety, or post-traumatic stress disorder. Participants had completed surveys about their mental health and had their heart … Continue reading Group statistics don’t necessarily describe an individual
