The Rockefeller University: "Chronic stress affects attention by altering neuronal growth in the brain"

ᔥ Working neuron by neuron, researchers have found that life experiences actually appear to change the length and complexity of individual brain cells.

In a recent study published in The Journal of Neuroscience, Rockefeller University scientists show that chronic daily stress affected neurons in two different areas of the rat brain. Unlike a typical rat neuron, the growth of neurons in stressed rats can be impacted by traumatic experiences. For the first time a link has been demonstrated between anxiety symptoms and the dynamic anatomy of the brain.

One of the characteristic manifestations of prolonged stress is decreased performance in tasks that require attention, including the ability to shift focus as well as to learn and unlearn information.
