Physical activity may leave the brain more open to change

Learning, memory, and brain repair depend on the ability of our neurons to change with experience. Now, researchers reporting in the Cell Press journal Current Biology on December 7 have evidence from a small study in people that exercise may enhance this essential plasticity of the adult brain.

The findings focused on the visual cortex come as hopeful news for people with conditions including amblyopia (sometimes called lazy eye), traumatic brain injury, and more, the researchers say.

"We provide the first demonstration that moderate levels of physical activity enhance neuroplasticity in the visual cortex of adult humans," says Claudia Lunghi of the University of Pisa in Italy.

"By showing that moderate levels of physical activity can boost the plastic potential of the adult visual cortex, our results pave the way to the development of non-invasive therapeutic strategies exploiting the intrinsic brain plasticity in adult subjects," she adds.

The plastic potential of the cerebral cortex is greatest early in life, when the developing brain is molded by experience. Brain plasticity is generally thought to decline with age. This decline in the brain's flexibility over time is especially pronounced in the sensory brain, which displays far less plasticity in adults than in younger people.

80% Support of the European Public for the Ban of Monsanto GMO Corn. Why are Americans ok with it?

Italy to Ban Monsanto GMO Corn with 80% Public Support

First India gives Monsanto a run for their ill-gotten money by refusing their patent applications, and now Italy, with the help of three Italian ministries, will try to undo Monsanto. A decree has been signed which will ban Monsanto’s MON810 maize, one of the two genetically modified crops currently legally grown in Europe and sold commercially. The decree is not yet binding as it has to be published in the official gazette, but the public stands behind the three Italian ministers who put forth the document with a resounding 80% against GMO and Monsanto, as evidenced in a public survey.
The agricultural ministry rightfully addressed one of many problems with Monsanto’s GMO crops, stating that they have a ‘negative impact on biodiversity.’ The ban was also signed by the health and environment ministries. That makes three. The ministries stated:

“Our agriculture is based on biodiversity, on quality, and those we must continue to aim for, without games that even from an economic point of view would not make us competitive.”

The three ministries have also notified the European Commission and other states in the EU about this important precedent-setting move to oust Monsanto from the world food supply monopoly that the company is currently trying to browbeat the world with. The ministries have also requested a scientific basis for the final decision from the European Food and Safety Authority – Europe’s version of the FDA, the country’s food safety watch dog.
