New technique may uncover answers to drug addiction

By Staff Writer

A recent study from the Stanford University found that deep regions of the brain can now be examined at a cellular level. Researchers used time-lapse fluorescence microdoscopy, which uses miniature probes to visualize specific cells over time.

The technique will allow scientists to explore changes that occur in neurons, which could result in finding how the brain adapts and adjusts to repeated drug exposure.

Researchers said that repeated drug use can lead to change in neuron circuits, which can be seen even after a person is treated. The study focused on the hippocampus and the striatum regions of the brain. The straitum part of the brain is critical for motor function and habit formation.

Researchers said that they believe that this region of the brain is partly responsible for the progression from voluntary drug use to addiction. They added that this technique will enable scientists to examine the reward system.

This study may lead to the development of cognitive therapy that could help individuals overcome addiction.

A 2008 report from the the Centers for Disease Control and Prevention shows that nearly 8 percent of individuals age 12 and older have used an illicit drug in the month leading up to the study.
