Posttraumatic stress disorder reveals imbalance between signalling systems in the brain

Posttraumatic stress disorder reveals imbalance between signalling systems in the brain | Science, Technology, and Current Futurism | Scoop.it
It has previously been shown that people with PTSD have altered brain anatomy and function. A new study by researchers from the Department of Psychology at Uppsala University and Clinical Neuroscience at Karolinska Institutet shows that people with PTSD have an imbalance between two neurochemical signalling systems of the brain, serotonin and substance P.
Sharrock's insight:

Interesting research support that experiences can significantly change brain. 

 

"The study, which has been published in the renowned scientific journal Molecular Psychiatry, shows that it is the imbalance between the two signalling systems which determines the severity of the symptoms suffered by the individual rather than the degree of change in a single system. Others have previously speculated that the biological basis of psychiatric disorders such as PTSD includes a shift in the balance between different signalling systems in the brain but none has yet proved it. The results of the study are a great leap forward in our understanding of PTSD. It will contribute new knowledge which can be used to design improved treatments for traumatised individuals."

Circadian Surprise: How Our Body Clocks Help Shape Our Waistlines

Circadian Surprise: How Our Body Clocks Help Shape Our Waistlines | Science, Technology, and Current Futurism | Scoop.it
scientists have made a cool discovery: We have different clocks in virtually every organ of our bodies — from our pancreas to our stomach to our fat cells.

"Yes, there are clocks in all the cells of your body," explains Fred Turek, a circadian scientist at Northwestern University. "It was a discovery that surprised many of us."
Sharrock's insight:

I've seen this in other research, especially regarding perception and cognition. Charisma, for example, is correlated with speed (frequency) and volume (amplitude) of speech/delivery and the intensity of gestures. Increasingly, research points to how we socially analyze based on timing.

Hair Regrowth Discovery Suggests Skin Cells Communicate Like Bacteria

Hair Regrowth Discovery Suggests Skin Cells Communicate Like Bacteria | Science, Technology, and Current Futurism | Scoop.it
A chemical signaling system called quorum sensing allows those single-celled bugs to detect when their numbers have multiplied enough to mount an effective attack or emit glowing light. Yet decades after scientists learned about this brainless bacterial coordination a research team has uncovered new evidence suggesting animal cells may speak the same lingo.

Programming smart molecules for chemical-based AI | KurzweilAI

“This work shows that it is possible to also build intelligent machines at tiny scales, without needing anything that looks like a regular computer. This kind of chemical-based AI will be necessary for constructing therapies that sense and adapt to their environment. The hope is to eventually have drugs that can specialize themselves to your personal chemistry and can diagnose or treat a range of pathologies.”
