Women's exercise linked to lower cognitive skill - health - 07 January 2011 WOMEN who habitually take strenuous exercise might be at risk of damaging their cognitive function later in life. Strenuous exercise is known to reduce oestrogen levels in women and girls. This can delay the start of menstruation, and can lead to irregular periods in adult women. Low levels of oestrogen in premenopausal women have been linked to impaired mental function in later life. Mary Tierney at the University of Toronto, Canada, reasoned that strenuous exercise might therefore lead to impaired cognition in later life. She asked 90 healthy post-menopausal women to report their life-long exercise habits, and then tested their cognitive ability. The overall benefits of regular exercise are well established, but Tierney says the possible impact of strenuous exercise on cognition should be investigated further to see if it is significant.

Brain Games & Brain Training Where is The Mind?: Science gets puzzled and almost admits a non-local mentalscape. This will be the last "home-produced" blog entry for a while [save the short "Everyday Spirituality" which will follow it as a sign-off] . West Virginia beckons tomorrow morning and off I will go to whatever that entails. As I said in one of the commentary responses the other day, I hope that reading two journal runs "cover-to-cover" will bring up a few thoughts worth sharing. The first of these articles [both from the New Scientist] was "Where in the World is the Mind?" That brings in the second serendipitous article. It reminded me then, also, of a moment when I was able to spend a [too short] time with David Bohm, the famous theoretical physicist. I am happy to be [in body] a holographic projection of force dimensions--not from the "edge" of the universe but its core reality.
Body of Thought: How Trivial Sensations Can Influence Reasoning, Social Judgment and Perception Why do we look up to those we respect, stoop to the level of those we disdain and think warmly about those we love? Why do we hide dirty secrets or wash our hands of worries? Why do we ponder weighty subjects and feel a load lift after we have made a decision? Why do we look back on the past and forward to the future? Such turns of phrase, invoking a physical reality that stands in for intangible concepts, might seem like linguistic flights of fancy.

Can't relax? It's all in your mind: Research shows stopping a thought puts more strain on the brain (PhysOrg.com) -- Turns out, relaxing is exhausting—which could by why so many people struggle to unplug from work during vacation. According to mathematicians at Case Western Reserve University, stopping a thought burns more energy than thinking-like stopping a truck on a downhill slope. "Maybe this explains why it is so tiring to relax and think about nothing," says Daniela Calvetti, professor of mathematics and one of the authors of a new brain study published in an advanced online publication of the Journal of Cerebral Blood Flow & Metabolism. Since opening up the brain for detailed monitoring isn't exactly practical, Calvetti teamed up with fellow mathematics professor Erkki Somersalo and Rossana Occhipinti, a postdoctoral researcher in physiology and biophysics, to create a computer model of brain metabolism. Calvetti and Somersalo created a software package specifically designed to study the complex metabolic systems.

NewbergPaperback, 284 pagesAshgateList price: $29.95 "Neurotheology" is a unique field of scholarship and investigation that seeks to understand the relationship specifically between the brain and theology, and more broadly between the mind and religion. As a topic, neurotheology has garnered substantial attention in the academic and lay communities in recent years. If neurotheology is to be considered a viable field going forward, it requires a set of clear principles that can be generally agreed upon and supported by both the theological or religious perspective and the scientific one as well. It is important to infuse throughout the principles of neurotheology the notion that neurotheology requires an openness to both the scientific as well as the spiritual perspectives. In short, for neurotheology to be successful, science must be kept rigorous and religion must be kept religious. 1. 2. 3. 4.
uld a mind-reading machine soon be a reality? Scientists 'decode' human brainwaves By Daily Mail Reporter Updated: 08:37 GMT, 18 May 2011 A 'mind-reading machine' that can display mental images is a step closer after scientists decoded brain signals related to vision, it was claimed today. Researchers from the University of Glasgow showed six volunteers images of people's faces displaying different emotions such as happiness, fear and surprise. In a series of trials, parts of the images were randomly covered so that, for example, only the eyes or mouth were visible. Nowhere to hide: A 'mind-reading machine' that displays mental images is a step closer after scientists said they have decoded brain signals related to vision Participants were then asked to identify the emotion being displayed while electrodes attached to the scalp measured the volunteers' brainwaves. The scientists were able to show that brainwaves varied greatly according to which part of the face was being looked at. 'What we have done is to find a way of decoding brainwaves to identify the messages within.'
How to Meditate What should I do if my legs fall asleep while meditating? This is common for new meditators, and will likely get better over time if you stick with it. As long as feeling comes back to your legs within a few minutes after changing position, don’t worry about it. If it persists or bothers you too much, try a different position, like sitting on a higher cushion, a chair, or lying down. The important part of meditation is your mind, not your body position. Which kind of meditation is best for someone with anxiety? Most types of meditation will teach you to calm your mind and be more aware of your thoughts and emotions, which will help with anxiety. Can I still meditate if I’m not religious? Absolutely. How can I stop myself from thinking while I meditate? Many of the techniques listed in this article will help you focus your mind on something other than your own thoughts.
Religion May Cause Brain Atrophy -- Science of the Spirit Faith can open your mind but it can also cause your brain to shrink at a different rate, research suggests. Researchers at Duke University Medical Centre in the US claim to have discovered a correlation between religious practices and changes in the brains of older adults. The study, published in the open-access science journal, Public Library of Science ONE, asked 268 people aged 58 to 84 about their religious group, spiritual practices and life-changing religious experiences. Changes in the volume of their hippocampus, the region of the brain associated with learning and memory, were tracked using MRI scans, over two to eight years. Protestants who did not identify themselves as born-again were found to have less atrophy in the hippocampus region than did born-again Protestants, Catholics or those with no religious affiliation. Although the brain tends to shrink with age, atrophy in the hippocampus has been linked with depression and Alzheimer's disease.

Méthode des six chapeaux La méthode des six chapeaux, extraite de l'ouvrage Six chapeaux pour penser[1],[2], est une méthode de structuration de la pensée personnelle ou de groupe, développée par Edward de Bono, permettant de résoudre les problèmes en favorisant la pensée critique et en évitant la censure précoce des idées nouvelles, dérangeantes ou inhabituelles[3]. Selon Karadag et al., cette méthode permet de développer la pensée créative en présentant et en systématisant des pensées et des suggestions dans un format spécifiquement défini[4]. Pour cela, les participants sont invités à aborder la question en prenant ensemble tour à tour différents « chapeaux » d'une couleur particulière. L'ordre d'adoption des chapeaux varie en fonction du type de problème. L'enjeu est de mobiliser un processus de « pensée parallèle » simple et efficace qui aide les gens à sortir des limites de l'étroitesse d'esprit, de la pensée unidirectionnelle et des positions fixes (De Bono, 1985[1]).
