Brain Mapping: Possible Road to a Cure

FRESNO, Calif.

Dr. Mayank Mehta is one of a number of researchers at UCLA studying the secrets of the human brain.

"We hope this could help us understand what goes wrong in Alzheimer's disease," Dr. Mayank Mehta, Professor of Neurology, Physics, and Astronomy at UCLA said.

Mehta mapped neuron patterns that form when rats do simple tasks in hopes of learning more about how different sections of the brain communicate.

"The brain has its own dynamics, its own laws of physics. If that goes wrong, clearly it will play a role in loss of memory, such as Alzheimer's or PTSD," Dr. Mehta explained.

Diseases that Dr. Arthur Toga says may one day be treated with targeted therapies using brain mapping.

"Our ability to look at a living brain of an individual that has a disease, or has had a traumatic brain injury, has allowed us to target exactly what has happened and suggest various therapies," Arthur Toga, Director of the UCLA Laboratory of Neuro Imaging said.

For the first time, Dr. Toga's team has mapped the progression of Alzheimer's in the brain.

"The net result is almost a four dimensional map showing you the trajectory of loss of tissue," Dr. Toga said.

While understanding and unlocking the secrets of the brain may take many years, researchers say it will be worth it when those secrets lead to treatments and possible cures.

"Well, every few months is a bigger breakthrough," Dr. Toga said.

Researchers say they'd eventually like a large library of brain maps that will help them compare brains of people who suffer from similar diseases. This library will help doctors across the world give personalized treatment to each patient.
