Scientists adapt economics theory to trace brain's information flow - 1 views

Granger's original objective was to see if links could be established that allowed economists to use current economic data to forecast changes in the economy in the near future. But first author Steven L. Bressler, Ph.D., professor of psychology at Florida Atlantic University, suspected the technique might help reveal if one brain area was passing data to or influencing another brain area.

Your Child's Growing Brain | ParentCenter - 0 views
-
Most of the brain's wiring is established during the first few years of life. At birth it was only about a quarter of its eventual adult size. But by age 2, it has reached three-fourths of adult size! And by 5, the brain will be very close to adult size and volume.
-
Surprisingly, the brain of a 2-year-old has trillions of connections — double the number that an adult has! The brain grows connections in response to all kinds of input in order to adapt and survive. Over time, certain connections are used again and again while others fall by the wayside
Study provides new insights about brain organization - 0 views

"One theory is that individual senses have separate areas of the brain dedicated to them," said Mark Wallace, Ph.D., the study's lead investigator. "In this view, information is processed initially on a sense-by-sense basis and doesn't come together until much later. However, this view has recently been challenged by studies showing that processing in the visual area of the brain, for example, can be influenced by hearing and touch."

Every drink shrinks the brain, warns new research | theage.com.au - 3 views
-
The American research, which looked at brain scans of more than 1800 people, comes after Australia's National Health and Medical Research Council released draft guidelines warning that more than two drinks a day posed a health risk.
-
Their MRI scans revealed brain volume of moderate drinkers was almost 1% smaller than teetotallers while those who had 14 or more drinks a week suffered 1.2% shrinkage.

Golden Swamp » Standards and synapses are very different - 0 views

I put the Illinois Learning Standards and the Synapse side-by-side to suggest that we require students to learn subjects inside of little boxes, while students think about them in highly connected networks. The boxes in the Standards are separated from each other in all sorts of ways: living things are in different boxes than processes of the Earth. Different things about the same subject are spread out over five different grade levels. There seems little chance of having a thought that relates an early box in “A” to a late box in “E.”

The situation is much the same in primates and rodents, where new neurons only appear in the hippocampus and olfactory bulb. In contrast, fish, reptiles and birds renew the neurons throughout their entire network and throughout their entire lives.
