  Abstract

  The effectiveness of suboptimal affective primes in real media applications has remained debatable. We investigated the effects of suboptimally (at 10-ms exposure) presented facial expression primes on emotional responses to, and cognitive evaluations of, textual (business news) messages ranging from slightly unpleasant to slightly pleasant among 33 participants. Facial expression primes were presented repeatedly on a simulated small screen of a mobile device during a news reading task. Facial electromyography (EMG) recordings were used as physiological indices of positive and negative emotions. Our results showed affective congruency effects between news messages and facial expression primes: joyful facial expressions, compared to angry primes or no priming, elicited higher positive affect evaluations and more positive facial EMG responses, as well as higher interest, when embedded in affectively more positive news. On the other hand, the mere presence of suboptimal primes was detrimental to the perceived trustworthiness of news. These results suggest that embedding suboptimal facial expression primes into textual media messages may exert an influence on affectively congruent messages; at the same time, our results highlight the potential hazards and difficulties of utilizing such primes.

Increased Coupling of Intrinsic Networks in Remitted Depressed Youth Predicts Rumination and Cognitive Control

Rachel H. Jacobs and 

Lisanne M. Jenkins, et. al.

Published: August 27, 2014DOI: 10.1371/journal.pone.0104366

"The authors have chosen to investigate a common symptom in most individuals who experience depression as well as those who suffer from many other psychiatric conditions.  Moreover, the capacity to choose what one wishes to think about without the mood-changing interruptions of invasive rumination and obsession may be less common than previously considered in many individuals with or without a psychiatric diagnosis.

Anecdotally, my experience with N-Acetyl Cysteine  in psychiatric patients (as well as personal-development clients with rumination and obsession who carry no official psychiatric diagnosis) suggests a potentially significant beneficial effect.  It would appear that the authors have established an evaluation paradigm with which this finding might be tested.

Abstract

Clinicopathological evidence suggests that the pathology of Alzheimer’s disease (AD) begins many years before the appearance of cognitive symptoms. Biomarkers are required to identify affected individuals during this asymptomatic (“preclinical”) stage to permit intervention with potential disease-modifying therapies designed to preserve normal brain function. Studies of families with autosomal-dominant AD (ADAD) mutations provide a unique and powerful means to investigate AD biomarker changes during the asymptomatic period. In this biomarker study, we collected cerebrospinal fluid (CSF), plasma, and in vivo amyloid imaging cross-sectional data at baseline in individuals from ADAD families enrolled in the Dominantly Inherited Alzheimer Network. Our study revealed reduced concentrations of CSF amyloid-β_1–42 (Aβ_1–42) associated with the presence of Aβ plaques, and elevated concentrations of CSF tau, ptau₁₈₁ (phosphorylated tau₁₈₁), and VILIP-1 (visinin-like protein-1), markers of neurofibrillary tangles and neuronal injury/death, in asymptomatic mutation carriers 10 to 20 years before their estimated age at symptom onset (EAO) and before the detection of cognitive deficits. When compared longitudinally, however, the concentrations of CSF biomarkers of neuronal injury/death within individuals decreased after their EAO, suggesting a slowing of acute neurodegenerative processes with symptomatic disease progression. These results emphasize the importance of longitudinal, within-person assessment when modeling biomarker trajectories across the course of the disease. If corroborated, this pattern may influence the definition of a positive neurodegenerative biomarker outcome in clinical trials.

But, It's Only a Dog...?

Feeling Simpatico with Your Dog? It May Be Based on Similar Human–Canine Brain Structures

New research shows that humans and dogs have very similar voice-sensitive brain regions, which may help explain our intense bonds with these furry, four-legged friends

You may snicker when you see dog owners talk to their pets as though they were human or view YouTube videos of dogs supposedly speaking English back to their owners, saying words like “banana” and “I love you.” And with good reason: although dogs have the capacity to understand more than 100 words, studies have demonstrated Fido can’t really speak human languages or comprehend them with the same complexity that we do. Yet researchers have now discovered that dog and human brains process the vocalizations and emotions of others more similarly than previously thought. The findings suggest that although dogs cannot discuss relativity theory with us, they do seem to be wired in a way that helps them to grasp what we feel by attending to the sounds we make.

To compare active human and dog brains, postdoctoral researcher Attila Andics and his team from MTA-ELTE Comparative Ethology Research Group in Hungary trained 11 dogs to lie still in an fMRI brain scanner for several six minute intervals so that the researchers could perform the same experiment on both human and canine participants. Both groups listened to almost two hundred dog and human sounds—from whining and crying to laughter and playful barking—while the team scanned their brain activity.

The resulting study, published in Current Biology today, reveals both that dog brains have voice-sensitive regions and that these neurological areas resemble those of humans. Sharing similar locations in both species, they process voices and emotions of other individuals similarly. Both groups respond with greater neural activity when they listen to voices reflecting positive emotions such as laughing than to negative sounds that include crying or whining. Dogs and people, however, respond more strongly to the sounds made by their own species. “Dogs and humans meet in a very similar social environment but we didn’t know before just how similar the brain mechanisms are to process this social information,” Andics says.

These striking similarities help clarify the timeline and stages of mammalian evolutionary history. Until now researchers had identified voice-sensitive brain regions only in humans and macaque monkeys, whose last common ancestor lived 30 million years ago. The last common ancestor of humans and dogs—a mammalian carnivore with a brain the size of an egg—existed around 100 million years ago. The canine finding thus suggests that the voice-sensitive brain regions in both species evolved at least that long ago, if not earlier. Other mammals on the same evolutionary branch as humans and hounds that also arose from that last mutual ancestor likely share the same brain areas as well.

But dog owners might be most interested in what this study says about our special relationship with canine pets. Humans domesticated dogs somewhere between 18,000 and 32,000 years ago, and since then they have become people’s best friends, hunting partners, guards and even purse accessories. Andics thinks the parallel brain sensitivity to voices and emotions may account in part for our unique bond. “This similarity helps explain what makes vocal communication between dogs and humans so successful,” he says. “It’s why dogs can tune into their owners’ feelings so well.”

Turns out, people who talk to their poodles or golden retrievers aren’t so silly after all.

Abstract

The nature of consciousness, the mechanism by which it occurs in the brain, and its ultimate place in the universe are unknown. We proposed in the mid 1990ʼs that consciousness depends on biologically ‘orchestrated’ coherent quantum processes in collections of microtubules within brain neurons, that these quantum processes correlate with, and regulate, neuronal synaptic and membrane activity, and that the continuous Schrödinger evolution of each such process terminates in accordance with the specific Diósi–Penrose (DP) scheme of ‘objective reduction’ (‘OR’) of the quantum state. This orchestrated OR activity (‘Orch OR’) is taken to result in moments of conscious awareness and/or choice. The DP form of OR is related to the fundamentals of quantum mechanics and space–time geometry, so Orch OR suggests that there is a connection between the brainʼs biomolecular processes and the basic structure of the universe. Here we review Orch OR in light of criticisms and developments in quantum biology, neuroscience, physics and cosmology. We also introduce a novel suggestion of ‘beat frequencies’ of faster microtubule vibrations as a possible source of the observed electro-encephalographic (‘EEG’) correlates of consciousness. We conclude that consciousness plays an intrinsic role in the universe.

Highlights

•

The Orch OR theory proposes quantum computations in brain microtubules account for consciousness.

•

Microtubule ‘quantum channels’ in which anesthetics erase consciousness are identified.

•

Evidence for warm quantum vibrations in brain microtubules is cited.

•

Interference of microtubule vibrations are ‘beat frequencies’ seen as EEG.

•

Orch OR links consciousness to processes in fundamental space–time geometry.

Potential Neuroscience Breakthrough May Advance Psychotherapy Practice

If this study is replicated, it could be a major breakthrough in neuroscience, permitting clarification of the commonly misunderstood distinction among feelings, impulses and behaviors--a major problem in psychiatric treatment of "irresistible impulses," commonly seen in most mental health disorders, (intrusive, unwanted thoughts and feelings), but often inappropriately diagnosed. Examples include obsessive worry, self-criticism, and anger resulting in aggressive behavior designed to hide more vulnerable feelings from ourselves and others. Most people use the words anger and aggression interchangeably, despite the reality that anger is a feeling and aggression is a behavior. We often hear patients describe their aggressive behavior as a "necessary" outcome of their feelings of anger, denying that the behavior was "chosen." This is often better understood when one realizes that the feelings of anger are usually "used" to hide from ourselves, more vulnerable feelings, such as helplessness, shame, abandonment, or other feelings of being hurt. Once the neuro-circuitry is elaborated, trans-cranial magnetic stimulation, pharmaceutical or neutraceutical (eg. N-Acetylcysteine, NAC) modification together with effective psychotherapeutic reframing of thoughts and feelings content, could replace the electricity-induced model. Because of neurons' plasticity, many of these modalities, including effective psychotherapy alone, have been postulated to produce neurogenesis and the replacement of unwanted connections with more desirable tracts, often resulting in apoptotic removal of the undesirable tracts. If confirmed in peer reviewed research, this study should be considered a ground-breaking accomplishment.

Who Is Responsible for the Pandemic of Obesity (and its related diseases) Throughout the World?

How the Junk Food Industry Hooked America (and the World)

FEBRUARY 23, 2013, 12:52 PM

If you've eaten a baby carrot recently, and perhaps thought better of yourself for enjoying a healthy snack food, you are not alone. As obesity has become a national health concern, advertisers have turned to old tricks to market healthier products. Jeffrey Dunn, who once directed Coca-Cola's sales in North and South America, is currently atoning for his previous marketing efforts (bringing Coke into Brazil's poorest neighborhoods called favelas) by pitching healthy snacks to food producers using slogans such as "Eat ’Em Like Junk Food."

Through the 1990s, the food industry poured massive investments into making snack foods packed with sugar and fat, all under the guise of giving the customer what it wants. The research and development put into these snack foods is astounding, from measuring the rate at which foods dissolve in the mouth to the pressure per square inch needed to make a chip snap in half. While attempts are now being made at some corporations to respond to the public health crisis, solutions such as reducing the salt content in foods could ironically result in higher caloric intake per individual.
