Brain cells normally respond adaptively to bioenergetic challenges resulting from ongoing activity in neuronal circuits, and from environmental energetic stressors such as food deprivation and physical exertion. At the cellular level, such adaptive responses include the “strengthening” of existing synapses, the formation of new synapses, and the production of new neurons from stem cells. AtContinue reading “Brain metabolism in health, aging, and neurodegeneration”

Yoga and behavioral memory interventions for the aging brain
Yoga and behavioral memory interventions to prevent age-related cognitive decline A study examined changes in brain metabolites and structure among individuals undergoing memory training and yogic meditation. We demonstrated that memory training over 3 months is associated with decreased choline levels in bilateral hippocampus and increased gray-matter volume in dACC, suggesting that behavioral interventions likeContinue reading “Yoga and behavioral memory interventions for the aging brain”
Brain Metabolism Predicts Fluid Intelligence in Young Adults
A healthy brain is critical to a person’s cognitive abilities, but measuring brain health can be a complicated endeavor. A new study by University of Illinois researchers reports that healthy brain metabolism corresponds with fluid intelligence – a measure of one’s ability to solve unusual or complex problems – in young adults. The results areContinue reading “Brain Metabolism Predicts Fluid Intelligence in Young Adults”
Brain Benefits of Aerobic Exercise Lost to Mercury Exposure
Summary: Researchers report adults with higher prenatal exposure to methylmercury, as a result of fish consumption, did not experience faster cognitive processing or short term memory benefits following exercise. Source: NIH/NIEHS. Cognitive function improves with aerobic exercise, but not for people exposed to high levels of mercury before birth, according to research funded by theContinue reading “Brain Benefits of Aerobic Exercise Lost to Mercury Exposure”
How to test movement in the gym using ROM as biofeedback
Exercise and Biofeedback Biofeedback testing is a way to measure your body’s own feedback in response to a stimulus like exercise. While advanced hardware technology exists to measure things like heart rate variability (HRV), muscle strength, or reflex speed testing your range of motion is free, easy, and you already have all the equipment youContinue reading “How to test movement in the gym using ROM as biofeedback”
Contributing factors to aging
It has been a long standing goal to develop molecular biomarkers of biological age. Recent studies demonstrate that powerful epigenetic biomarkers of aging can be defined based on DNA methylation levels. For example, the epigenetic clock (PMID: 24138928) is a multivariate age estimation method that applies to sorted cell types (CD4T cells or neurons), complexContinue reading “Contributing factors to aging”
Exercise beyond menopause: Dos and Don’ts
With a significant number of women belonging to the status of menopause and beyond, it is imperative to plan a comprehensive health program for them, including lifestyle modifications. Exercise is an integral part of the strategy. The benefits are many, most important being maintenance of muscle mass and thereby the bone mass and strength. TheContinue reading “Exercise beyond menopause: Dos and Don’ts”
Anabolic and catabolic process, hormones and exercise
The body faces a catabolic state during normal metabolic functions. This idea, opposed to an anabolic state, actually defines the breakdown of foods and nutrients so that they will later have the ability to build up and add to the muscle or tissue growth process. Exercise Catabolic exercises are largely aerobic, meaning they consume oxygen,Continue reading “Anabolic and catabolic process, hormones and exercise”
What is your molecular age? P16 protein can ID your molecular age
Aging biomarket test – coming soon Researchers report the development of a new blood test that they say may show your “molecular age,” as opposed to your chronological age. That test measures levels of a protein called p16. A new study shows that p16 levels rise as people age, that smokers have higher levels ofContinue reading “What is your molecular age?

Behavior, brain SPECT scan, hormones, gratitude, neuroplasticity
Neuroplasticity, also known as brain plasticity, is an umbrella term that describes lasting change to the brain throughout an individual’s life course. The term gained prominence in the latter half of the 20th century, when new research[1] showed many aspects of the brain remain changeable (or “plastic”) even into adulthood.[2] This notion contrasts with theContinue reading “Behavior, brain SPECT scan, hormones, gratitude, neuroplasticity”
Exercise to fight cancer
by WAlter Last Adequate physical activity is one of the main requirements for achieving and maintaining good health. Deep breathing while exercising is essential: lack of oxygen – becoming breathless – is harmful. ‘Aerobic’ exercises are those that can be maintained for long periods, because the heart and lungs can supply enough oxygen to theContinue reading “Exercise to fight cancer”
150 min of moderate-intensity exercise per week
500 metabolic equivalents per week (MET/week) or 150 min of moderate-intensity exercise per week reduces the occurrence of major cancers by 20%. METs and MET-minutes A well-known physiologic effect of physical activity is that it expends energy. A metabolic equivalent, or MET, is a unit useful for describing the energy expenditure of a specific activity.Continue reading “150 min of moderate-intensity exercise per week”
Regeneration of our cells, brain metabolism and exercise
This is my third week at cross fit exercise training. I wanted to know how my body can regenerate. The human body is an incredible machine. Part of what makes it so impressive (apart from the concept of conciousness and self awareness) is its ability to regenerate itself. Your outer layer of skin, the epidermisContinue reading “Regeneration of our cells, brain metabolism and exercise”
Hypocretin, Insomia or Sleep Disturbances, Narcolepsy, Depression and Parkinson’s
Drowsy Driving Driving and feeling sleepy. Repetitive tasks make you sleepy because you already lack sleep. You have taken your calcium and magnesium and melatonin and the bedroom has cool environment. Still, you have worries and you keep tossing back and forth on your bed. You cannot get the more than 5 hrs sleep. YourContinue reading “Hypocretin, Insomia or Sleep Disturbances, Narcolepsy, Depression and Parkinson’s”
