This 2015 California human study was of the dorsal anterior cingulate cortex (dACC): “No neural region has been associated with more conflicting accounts of its function than the dACC. The best psychological description of dACC function was related to pain processing—not executive, conflict, or salience processing. We conclude by considering that physical pain may be … Continue reading The function of the dorsal ACC is to monitor pain in survival contexts
This 2018 Baltimore cell study found: “Based on similarities in overall methylation patterns in replicative senescence and cancers, it is hypothesized that tumor-promoting DNA methylation in cancers derives from cells escaping senescence. We show that the tumor-associated methylation changes evolve independently of senescence and are pro-survival events with functional implications contrasting that in senescence. In … Continue reading Cell senescence and DNA methylation
This 2018 McGill/UC San Diego rodent study was on the dentate gyrus area of the hippocampus: “Early life experience influences stress reactivity and mental health through effects on cognitive-emotional functions that are, in part, linked to gene expression in the dorsal and ventral hippocampus. The hippocampal dentate gyrus (DG) is a major site for experience-dependent … Continue reading An emotional center of our brains
I’m an avid reader of science articles, abstracts, studies, and reviews. I tried a free subscription to Singularity Hub for a few weeks last month because it seemed to be a suitable source of articles on both science and technology. I unsubscribed after being disappointed by aspects of science and technology hijacked almost on a … Continue reading Science and technology hijacked by woo
Most of the spam I get on this blog comes in as ersatz comments on The hypothalamus couples with the brainstem to cause migraines. I don’t know what it is about the post that attracts internet bots. The unwanted attention is too bad because the post represents a good personal illustration of “changes in the … Continue reading How to cure the ultimate causes of migraines?
The fifth and final paper of Transgenerational epigenetic inheritance week was a 2017 German/Italian meta-analysis of psychiatric treatments involving human children: “The transgenerational transmission of mental disorders is one of the most significant causes of psychiatric morbidity. Several risk factors for children of parents with mental illness (COPMI) have been identified in numerous studies and meta-analyses. … Continue reading Do preventive interventions for children of mentally ill parents work?
This December 2016 Australian review published in September 2017 concerned: “..the nutritional psychiatry field..the neurobiological mechanisms likely modulated by diet, the use of dietary and nutraceutical interventions in mental disorders, and recommendations for further research.” The reviewers inexplicably omitted acetyl-L-carnitine, which I first covered in A common dietary supplement that has rapid and lasting antidepressant … Continue reading A gaping hole in a review of nutritional psychiatry
Continuing with Dr. Arthur Janov’s May 2016 book Beyond Belief: “p. 17 When someone insults us, we immediately create reasons and rationales for it. We cover the pain. Now imagine a whole early childhood of insults and assaults and how that leaves a legacy that must be dealt with. ..The mind of ideas and philosophies … Continue reading Beyond Belief: The impact of merciless beatings on beliefs
This 2016 German human study with one subject found: “The hypothalamus to be the primary generator of migraine attacks which, due to specific interactions with specific areas in the higher and lower brainstem, could alter the activity levels of the key regions of migraine pathophysiology.” The subject underwent daily fMRI scans, and procedures to evoke … Continue reading The hypothalamus couples with the brainstem to cause migraines
This 2016 Italian review subject was the interplay of genetic imprinting and sleep regulation: “Sleep results from the synergism between at least two major processes: a homeostatic regulatory mechanism that depends on the accumulation of the sleep drive during wakefulness, and a circadian self-sustained mechanism that sets the time for sleeping and waking throughout the … Continue reading Genetic imprinting, sleep, and parent-offspring conflict
