NO ROAD, NO trail can penetrate this forest. The long and delicate branches of its trees lie everywhere, choking space with their exuberant growth. No sunbeam can fly a path tortuous enough to navigate the narrow spaces between these entangled branches. All the trees of this dark forest grew from 100 billion seeds planted together. And, all in one day, every tree is destined to die.
This forest is majestic, but also comic and even tragic. It is all of these things. Indeed, sometimes I think it is everything. Every novel and every symphony, every cruel murder and every act of mercy, every love affair and every quarrel, every joke and every sorrow — all these things come from the forest.

The Human Connectome Project: Progress and Prospects (Cerebrum):
“Understanding the human brain in health and disease represents a grand scientific challenge for the 21st century and beyond. How does a collection of 90 billion neurons interconnected by 150 trillion synapses give rise to the extraordinary capabilities of human behavior and the amazing diversity of talents among the billions of people populating our earth?” Keep reading The Human Connectome Project: Progress and Prospects over at the Dana Foundation website.

Boosting Synaptic Plasticity to Accelerate Learning (DARPA news):
“The body’s branching network of peripheral nerves connects neurons in the brain and spinal cord to organs, skin, and muscles, regulating a host of biological functions from digestion to sensation to locomotion. But the peripheral nervous system can do even more than that…pushing those limits further, DARPA aims to enlist the body’s peripheral nerves to achieve something that has long been considered the brain’s domain alone: facilitating learning.

Everyone experiences stress at some point in our lives. It is important to know that stress can harm the brain, and also that dance can be a great avenue for a person resist, reduce, or escape it.
Stress can change the physical structure and function of the brain, affecting wiring and thus performance of one’s activities. Read the rest of this entry »
