The Baby’s Brain: Wider Than The Sky
Explain migrations-how millions of neurons travel in waves and follow cues along the way telling them exactly where to go?
Neurons travel everyday in millions to carry out different task. It’s fascinating how they travel as if they are traveling across the country. They’re following cues along the way that are telling them exactly where to go. Evidence shows that young neurons have an idea about where they migrate to and can recognize their position within the brain. Neuroniologist Susan McCnell devised a series of experiment to track the destiny of a migrating neuron. Dr. McCnell found that the fate of the soon-to-become neuron was determined by his neighbor neuron. It travel beside its neighbor and took on the same function they did. The new neuron then goes on its own path, and takes on an entirely different function from the cells surrounding it.

The child brain is plastic, a magnificent and flexible engine for learning. Children learn to crawl, reason, pay attention and remember.

I can relate being the eldest of my siblings’ language development represents one of the most profound mysterious changes.

Explain how age affects mental performance?
The lab at the University of Michigan studies shows how age affects mental performance. Its director, psychologist Denise Park, gathers evidence that presents a new view of brain aging. Aging begins in our 20s, as soon as we reach maturity, our data show clearly as we age from twenty to...
