Standing still when a threat is detected is a defensive, protective reaction. This ancestral and automatic behavior allows the prey to stay unnoticed by a potential predator. A new study published in Psychophysiology finds that humans, like many other complex animals, freeze when encountering a threat. The mere picture of an injured or mutilated human induces this reaction. When viewing these unpleasant images, the study’s participants froze as their heart rate decelerated and amount of their body sway reduced. The authors found that this abrupt reaction, so critical for the survival of some animals, has stayed with humans.

Forty-eight male volunteers stood barefoot on a stabilometric platform, to measure balance and body sway, and viewed twenty-four pictures from three different categories. They were: pleasant (sports), neutral (objects), and unpleasant (injured or mutilated humans). Posturographic and electrocardiographic recordings were collected. The author found a significant reduction in body sway along with increased muscle stiffness following the unpleasant/mutilation block of pictures compared to the neutral pictures. The number of heartbeats per minute was also lower after viewing the mutilation pictures than after looking at the others. “This pattern resembles the ‘freezing’ and ‘fear bradycardia’ seen in many species when confronted with threatening stimuli, mediated by neural circuits that promote defensive survival,” author Eliane Volchan explains.

This study is published in the current issue of Psychophysiology. Media wishing to receive a PDF of the full article please contact [email protected]

Psychophysiology reports on new theoretical, empirical and methodological advances in: psychology and psychiatry, cognitive science, cognitive and affective neuroscience, social science, health science and behavioral medicine, and biomedical engineering. It is published on behalf of the Society for Psychophysiological Research.

The study is authored by Tatiana M. Azevedo, Eliane Volchan, Erika C. Rodrigues, Luiz G. Lutterbach, and Claudia D. Vargas from the Institute of Biophysics Carlos Chagas Filho, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil. And Luiz A. Imbiriba, José M. Oliveira, and Liliam F. Oliveira from the School of Physical Education, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil.

Eliane Volchan is an associate professor and work with a team of students and collaborators in the Institute of Biophysics Carlos Chagas Filho at the Federal University of Rio de Janeiro, Brazil. In 2005, Dr. 2005 Volchan was awarded the Comendador da Ordem Nacional do Mérito Científico, by the Presidency of the Republic of Brazil.

About the author:Mike Adams (aka the "Health Ranger") is a best selling author (#1 best selling science book on Amazon.com) and a globally recognized scientific researcher in clean foods. He serves as the founding editor of NaturalNews.com and the lab science director of an internationally accredited (ISO 17025) analytical laboratory known as CWC Labs. There, he was awarded a Certificate of Excellence for achieving extremely high accuracy in the analysis of toxic elements in unknown water samples using ICP-MS instrumentation. Adams is also highly proficient in running liquid chromatography, ion chromatography and mass spectrometry time-of-flight analytical instrumentation.

Adams is a person of color whose ancestors include Africans and Native American Indians. He's also of Native American heritage, which he credits as inspiring his "Health Ranger" passion for protecting life and nature against the destruction caused by chemicals, heavy metals and other forms of pollution.

Adams is the founder and publisher of the open source science journal Natural Science Journal, the author of numerous peer-reviewed science papers published by the journal, and the author of the world's first book that published ICP-MS heavy metals analysis results for foods, dietary supplements, pet food, spices and fast food. The book is entitled Food Forensics and is published by BenBella Books.

In his laboratory research, Adams has made numerous food safety breakthroughs such as revealing rice protein products imported from Asia to be contaminated with toxic heavy metals like lead, cadmium and tungsten. Adams was the first food science researcher to document high levels of tungsten in superfoods. He also discovered over 11 ppm lead in imported mangosteen powder, and led an industry-wide voluntary agreement to limit heavy metals in rice protein products.

In addition to his lab work, Adams is also the (non-paid) executive director of the non-profit Consumer Wellness Center (CWC), an organization that redirects 100% of its donations receipts to grant programs that teach children and women how to grow their own food or vastly improve their nutrition. Through the non-profit CWC, Adams also launched Nutrition Rescue, a program that donates essential vitamins to people in need. Click here to see some of the CWC success stories.

With a background in science and software technology, Adams is the original founder of the email newsletter technology company known as Arial Software. Using his technical experience combined with his love for natural health, Adams developed and deployed the content management system currently driving NaturalNews.com. He also engineered the high-level statistical algorithms that power SCIENCE.naturalnews.com, a massive research resource featuring over 10 million scientific studies.

Adams is well known for his incredibly popular consumer activism video blowing the lid on fake blueberries used throughout the food supply. He has also exposed "strange fibers" found in Chicken McNuggets, fake academic credentials of so-called health "gurus," dangerous "detox" products imported as battery acid and sold for oral consumption, fake acai berry scams, the California raw milk raids, the vaccine research fraud revealed by industry whistleblowers and many other topics.

Adams has also helped defend the rights of home gardeners and protect the medical freedom rights of parents. Adams is widely recognized to have made a remarkable global impact on issues like GMOs, vaccines, nutrition therapies, human consciousness.

In addition to his activism, Adams is an accomplished musician who has released over a dozen popular songs covering a variety of activism topics.
