Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Area of Science:

Neuroscience
Psychiatry
Neuroimaging

Background:

Internet addiction (IA) is a growing concern among adolescents.
Understanding the neurobiological underpinnings of IA is crucial.

Purpose of the Study:

To investigate brain gray matter density (GMD) differences in adolescents with IA.
Utilize voxel-based morphometry (VBM) on MRI data.

Main Methods:

Compared 18 IA adolescents with 15 healthy controls.
Acquired high-resolution T1-weighted structural MRI scans.
Performed VBM analysis to assess GMD variations.

Main Results:

IA adolescents exhibited significantly lower GMD.
Reduced GMD was observed in the left anterior cingulate cortex, left posterior cingulate cortex, left insula, and left lingual gyrus.

Conclusions:

Brain structural alterations are evident in adolescents with IA.
Findings suggest potential insights into the pathogenesis of Internet addiction.
