The resulting "noisy brain" might impair brain activity and disrupt cognitive processes, said Dr. Shikha Prashad, the study's lead author and a research scientist at the Center for BrainHealth.
"This study is the first to characterize global cortical activation and both inter- and intrahemispheric functional connectivity during resting state in cannabis users," said Prashad, who works in the lab of Dr. Francesca M. Filbey, the Bert Moore Chair in BrainHealth at UT Dallas.

The results of the study were published in the journal NeuroImage.
The researchers collected electroencephalogram (EEG) data from 38 participants in two groups: 17 cannabis users and 21 nonusers. The EEG test measures electrical activity in the brain -- also known as brain waves. Scientists measured the synchronization of brain waves to evaluate the strength of the brain signals in different cortical regions. Such coherence of the EEG signal is a measure of the communication between different regions of the brain.
