''' *MEMORY -MICE- METRICS* '''

THESE BRILLIANT RESEARCHERS  - divided  the animals into groups. Some, as a control, continued with their normal Rodent lives-

Others began running at will on wheels in their cages; mice seem to enjoy running and these eagerly covered about three miles a day.

After a month, some of the sedentary animals were exposed to three days of stressful experiences.

These mostly involved some type of mild mind restraint, which makes prey animals like mice  understandably anxious.

The researchers were trying to stimulate relatively chronic stress with the animals, somewhat like what most of us feel with ongoing work pressures or other anxieties.....................

Some of the runners were also restrained and stressed.

A  neurological study in these mice suggests that ''regular exercise'' of the sort those Tokyo Marathoners undertake can bolster communication between brain cells.

EXERCISE MAY JUST HELP the brain to build durable memories, through good times and bad.

Through all times.

Stress and adversity weaken the brain's ability to learn and return information, earlier research has found.

But according to a  remarkable new neurological study in mice, regular exercise can counteract those effects by bolstering communication between brain cells.

Memory has long been considered a biological enigma, a medley of mental ephemera that has some basis in material existence. Memories are coded into brain cells in the hippocampus, the brain's memory center.

If our memories were not written into those cells, they would not be available for later, long-term recall, and every brain would be like that of Dory, the memory-challenged fish in ''Finding Nemo.''

But representation of experience are extremely complex and aspects of most memories must be spread across multiple brain cells, neuroscientists have determined.

The cells must be able to connect with one another, so that the memory, as a whole, stays intact.

The connections between neurons, known as synapses, are composed of electrical and chemical signals that move from cell to cell, like notes passed in class.

The signals can be relatively weak and sporadic or flow with vigor and frequency. In general, the stronger the messages between neurons, the sturdier and more permanent the memories they hold.

Neuroscientists have known for some time that the potency of our synapses depends to some degree on how we live our lives.

Lack of our sleep, alcohol, diet and other aspects of our lifestyles, especially stress, may dampen the flow of messages between brain cells, while practice fortifies it.

Repeat an action and the signals between the cells maintaining the memory of that action can strengthen. That is learning.

There also have been hints that exercise might affect synapses in the hippocampus. Exercise has been shown in many studies to improve learning and memory.

But only a few past animal studies have closely tracked changes to synapses after exercise and none looked simultaneously at stress, leaving the results unrepresentative of actual life, which always contains some some amount of stress.

So, for the new study, which was published this month in Neurobiology of Learning and Memory, researchers at Brigham Young University in Provo, Utah, gathered healthy, male mice.

[They plan similar future studies with female mice].
