Playing violent video games changes both the structure & behaviour of the brain

Latest research presented to a conference in Sydney, Australia, on Friday 04 October, shows that exposure to violent video games has the following effects:

• Limits size of the pre-frontal cortex, the part of the brain which controls impulsive behaviour & rationality.

• Reduces activity in the pre-frontal cortex.

• Reduces sensitivity to violence.

These effects are both short & long term.
