Psychophysiological Coherence: “The Groove Is In The Heart”

8:59 pm in Uncategorized by mzchief

In prior posts (here and here), we have learned of the non-toxic, anti-cancer and anti-aging ("free-radical scavenger") properties of a typical component of the cannabis ("marijuana") plant called cannabidiol (CBD). We have also learned through review of some animal research that CBD is associated with the growth of new neurons in the brain. At this juncture, let me explicitly enunciate that the human body and, in specific, the brain are in actuality very elastic. I mentioned previously that it has been demonstrated that humans can and do build new neural pathways as has been again shown through the clinical application of computer-aided biofeedback technology in brain rehabilitative therapy and cognitive performance enhancement. The growth rates of cells and tissues (some organs are heterogeneous cell collections while others are not) of the body vary. For instance, in an adult human it can take about six months after a root canal for the bone cells to fill the holes left from the tooth extraction. Next, there tends to be the popular notion that the brain is the control center of the body. The fact of the matter is that it is not.

In 1915, Walter Bradford Cannon, M.D., discovered the stress response– changes in emotions are accompanied by predictable changes in heart rate, blood pressure, respiration and digestion– and thereby made a significant contribution to psychology and medicine. However, Cannon presumed that the brain was in control of the entire process.

In 1960s and 1970s John and Beatrice Lacey were some of the first modern psychophysiological researchers to examine information flow between the brain and the heart and observe that the heart communicates with the brain in ways that significantly affect human perception and reactions to the world. In 1974, French neurophysiologists Gahery and Vigier discovered a neural pathway and mechanism whereby input from the heart to the brain could "inhibit" or "facilitate" the brain’s electrical activity ("Inhibitory effects in the cuneate nucleus produced by vago-aortic afferent fibers." Brain Research. Volume 75, Issue 2, 26 July 1974, Pages 241-246. DOI:10.1016/0006-8993(74)90744-6.). Working with cats, Gahery and Vigier stimulated the vagus nerve and found that the brain’s electrical response was reduced to about half its normal rate. Therefore, the new evidence suggested that the heart and nervous system were not simply following the brain’s directions as previously assumed since Cannon.

In 1991, an early pioneer in neurocardiology, Dr. J. Andrew Armour, introduced the concept of a functional "heart brain." Armour found that:

The heart’s nervous system contains around 40,000 neurons, called sensory neurites, which detect circulating hormones and neurochemicals and sense heart rate and pressure information. Hormonal, chemical, rate and pressure information is translated into neurological impulses by the heart’s nervous system and sent from the heart to the brain through several afferent (flowing to the brain) pathways. It is also through these nerve pathways that pain signals and other feeling sensations are sent to the brain. These afferent nerve pathways enter the brain in an area called the medulla, located in the brain stem. The signals have a regulatory role over many of the autonomic nervous system signals that flow out of the brain to the heart, blood vessels and other glands and organs. However, they also cascade up into the higher centers of the brain, where they may influence perception, decision making and other cognitive processes.

The new research showed that the brain and nervous system was really a "distributed parallel processing system" composed of distinct but interplaying groups of neuronal processing centers disbursed throughout the body. Further, the heart had its own built-in nervous system that functions and processes information independently of the brain or the previously identified nervous system (e.g. why a heart transplant works; also see "The heart reinnervates after transplantation." Ann Thorac Surg 2000;69:1769-1781.).

Another piece of the heart-brain communication puzzle was provided by research on the hormonal system. In 1981, the heart was reclassified as an endocrine or hormonal gland when Atrial Natriuretic Factor (ANF) was isolated. ANF, a hormone produced and excreted by the heart, has a regulatory effect on the blood vessels, the kidneys and the adrenal glands and a large number of regulatory regions in the brain.

Dr. J. Andrew Armour and research team found that the heart contains a cell type known as "intrinsic cardiac adrenergic" (ICA) cells ("Capacity of intrinsic cardiac neurons to modify the acutely autotransplanted mammalian heart." J Heart Lung Transplant. 1994 Sep-Oct;13(5):847-56.). Such cells are considered "adrenergic" because they synthesize and release catecholamines (norepinephrine and dopamine), neurotransmitters previously thought to be produced only by neurons in the brain and ganglia outside the heart. An even more recent discovery is that the heart also secretes oxytocin, the "cuddle" or "love" hormone. Beyond its well-known functions in childbirth and lactation, recent evidence indicates that this hormone is also involved in cognition, tolerance, adaptation, complex sexual and maternal behaviors as well as in the learning of social cues and the establishment of enduring pair bonds. Concentrations of oxytocin in the heart are as high as those found in the brain (also see "Chronic Oxytocin Treatment Mediates Heart Rate Responses Following Social Isolation." 2007).

These findings show that the heart is actually:

a highly complex, self-organized information processing center with its own functional "brain" that communicates with and influences the cranial brain via the nervous system, hormonal system and other pathways. These influences profoundly affect brain function and most of the body’s major organs, and ultimately determine the quality of life.

{snip}

[w]hile two-way communication between the cognitive and emotional systems is hard-wired into the brain, the actual number of neural connections going from the emotional centers to the cognitive centers is greater than the number going the other way. [This in part explains] the tremendous power of emotions, in contrast to thought alone. Once an emotion is experienced, it becomes a powerful motivator of future behaviors, affecting moment-to-moment actions, attitudes and long-term achievements. Emotions can easily bump mundane events out of awareness, but non-emotional forms of mental activity (like thoughts) do not so readily displace emotions from the mental landscape.

So, an even more sophisticated application of recent research beyond the aforementioned computer-aided cranial brain-centric biofeedback technique is the self-moderated biofeedback technique of "meditation" or "psychophysiological coherence":

[..] individuals can gain more conscious control over the process of creating increased coherence within and between the mental and emotional systems than might be commonly believed. This, in turn, can lead to greater physiological coherence, manifesting as more ordered and efficient function in the nervous, cardiovascular, hormonal and immune systems. We call the resulting state psychophysiological coherence, as it involves a high degree of balance, harmony and synchronization within and between cognitive, emotional and physiological processes. Research has shown that this state is associated with high performance, reduced stress, increased emotional stability and numerous health benefits.

Key Cannabis Plant Compound Found to Have No Degrading Effect On Human Memory

6:40 pm in Uncategorized by mzchief

The first study to suggest that a key cannabis ("marijuana") plant compound, cannabidiol (CBD), can mitigate the interference of Δ9-THC ("THC") with memory formation was lead by Dr. Valerie Curran, PhD, a psychopharmacologist from University College London also studying the effects of cannabis use on creativity at the Beckley Foundation, Oxford, UK.

To test this hypothesis, Curran and her colleagues traveled to the homes of 134 volunteers, where the subjects got high on their own supply before completing a battery of psychological tests designed to measure anxiety, memory recall and other factors such as verbal fluency when both sober and stoned. The researchers then took a portion of the stash back to their laboratory to test how much THC and cannabidiol it contained.

The subjects were divided into groups of high (samples containing more than 0.75% cannabidiol) and low (less than 0.14%) cannabidiol exposure, and the data were filtered so that their THC levels were constant. Analysis showed that participants who had smoked cannabis low in cannabidiol were significantly worse at recalling text than they were when not intoxicated. Those who smoked cannabis high in cannabidiol showed no such impairment.

Ilan attributes the positive finding of Curran and her team to their more powerful methodology in analysing subjects’ own smoking preferences. In the United States, government policy dictates that only marijuana provided by the National Institute on Drug Abuse can be used for research — and it "is notorious for being low in THC and of poor quality", says Ilan.

Lester Grinspoon, professor emeritus of psychiatry at Harvard Medical School in Boston, Massachussetts, who has studied the effects of marijuana on patients since 1967, says that Curran’s study is important."Cannabis with high cannabidiol levels will make a more appealing option for anti-pain, anti-anxiety and anti-spasm treatments, because they can be delivered without causing disconcerting euphoria," he says.

- from "Key ingredient staves off marijuana memory loss," published online, Oct. 1, 2010, Nature. doi:10.1038/news.2010.508

Dr. Curran argues that cannabidiol studies could provide insight into the mechanics of memory formation and reveal therapeutic benefits for disorders involving memory impairments. The research was published October 1, 2010 in the British Journal of Psychiatry ("Impact of cannabidiol on the acute memory and psychotomimetic effects of smoked cannabis: naturalistic study," The British Journal of Psychiatry (2010) 197: 285-290. doi: 10.1192/bjp.bp.110.077503).

Pre-Clinical Study Shows Marijuana Compound Inhibits Tumor Size, Growth and Metastasis of Human Cancer

3:28 pm in Uncategorized by mzchief

Last week there was some pretty hot pre-clinical science news pre-published on-line in the journal, Breast Cancer Research and Treatment. Cannabidiol (CBD; note the benzene ring contained within the molecular structure), is one biochemical constituent in the cannabis ("marijuana") plant of which "only THC [Δ9-tetrahydrocannabinol] is psychoactive." "At least 66 other cannabinoids are also present in cannabis, including cannabidiol (CBD), cannabinol (CBN) and tetrahydrocannabivarin (THCV) among many others, which are believed to result in different effects from those of THC alone.[7]" ("Marijuana," accessed Sept. 28, 2010).

In the pre-clinical study conducted under lead researcher, Sean McAllister, PhD at The California Pacific Medical Center Research Institute, cannabidiol (CBD) was delivered directly to cells and found to inhibit tumor mass size, proliferation and invasion of human cancer cells. Also, it was demonstrated that treatment with CBD significantly reduces primary tumor mass as well as the size and number. For more than ten years, McAllister and his scientific team have been investigating the genes responsible for the spread of cancer. Cannibadiol was found in 2007 to inhibit the gene that controls the spread of cancer:

According to cancer researcher Yvez Desprez, Ph.D., "The problem is not the cancer itself, the problem is the spread of the cancer. When this type of gene [Id-1] is expressed, the cells basically go crazy and they’re very aggressive and they metastasize everywhere in the body." Dr. McAllister says, "We could expect that if we create really effective inhibitors against it, we could potentially treat many types of aggressive cancers." (from "Marijuana compound could help fight breast cancer," Nov. 19, 2007, ABC’s KGO-TV San Francisco).

One of the most exciting aspects of this announcement is that CBD may provide one of the only low- or non-toxic therapeutic alternatives to conventional chemotherapy and its associated adverse effects:

Invasion and metastasis of aggressive breast cancer cells are the final and fatal steps during cancer progression. Clinically, there are still limited therapeutic interventions for aggressive and metastatic breast cancers available. Therefore, effective, targeted, and non-toxic therapies are urgently required. Id-1 [..] has recently been shown to be a key regulator of the metastatic potential of breast and additional cancers. We previously reported that cannabidiol (CBD), a cannabinoid with a low toxicity profile, down-regulated Id-1 gene expression in aggressive human breast cancer cells in culture. [.. W]e determined pathways leading to the down-regulation of Id-1 expression by CBD and consequently to the inhibition of the proliferative and invasive phenotype of human breast cancer cells. [.. T]wo different syngeneic models of tumor metastasis to the lungs were chosen to determine whether treatment with CBD would reduce metastasis in vivo. We show that CBD inhibits human breast cancer cell proliferation and invasion [..]. Moreover, [..] we then show that treatment with CBD significantly reduces primary tumor mass as well as the size and number of lung metastatic foci in two models of metastasis. Our data demonstrate the efficacy of CBD in pre-clinical models of breast cancer. The results have the potential to lead to the development of novel non-toxic compounds for the treatment of breast cancer metastasis, and the information gained from these experiments broaden our knowledge of both Id-1 and cannabinoid biology as it pertains to cancer progression. (from "Pathways mediating the effects of cannabidiol on the reduction of breast cancer cell proliferation, invasion, and metastasis," Sept. 22, 2010)

Although this is the very careful, conditional language of the bench scientist, this is a pretty big deal– even for research considered at an early stage.

Cancer Research UK investigator, Dr. Joanna Owens, says:

[.. t]he findings will need to be followed up with clinical trials in humans to see if the CBD is safe, and whether the beneficial effects can be replicated. Several cancer drugs based on plant chemicals are already used widely, such as vincristine – which is derived from a type of flower called Madagascar Periwinkle and is used to treat breast and lung cancer. It will be interesting to see whether CBD will join them. (from "Cannabis compound ‘halts cancer’" Nov. 19, 2007, BBC News)

T-Mobile Blocks Texting Services for WeedMaps.Com, a California Medical Marijuana Dispensary. T-Mobile Gets Sued in NY Federal Court.

2:27 pm in Uncategorized by mzchief

Germany’s Deutsche Telekom operations in the US, T-Mobile USA, proves once again that it hates America by claiming the right to censor text messages with weedy, non-alcoholic un-churchy words that it doesn’t like:

The Bellevue, Washington-based wireless service is being sued by a texting service claiming T-Mobile stopped servicing its "short code" clients after it signed up a California medical marijuana dispensary. In a court filing, T-Mobile said it had the right to pre-approve EZ Texting’s clientele, which it said the New York-based texting service failed to submit for approval.

{ snip }

It’s the first federal case testing whether wireless providers may block text messages they don’t like.

The legal flap comes as the Federal Communications Commission has been dragging its feet over clarifying the rules for wireless carriers. The FCC was asked in 2007 to announce clear rules whether wireless carriers, unlike their wireline brethren, may ban legal content they do not support. The so-called "network neutrality" issue made huge headlines last month, when Google, along with Verizon, urged Congress not to bind wireless carriers to the same rules as wireline carriers.

T-Mobile, and a few other European Multinational Corporations, hate American workers for their freedoms too:
