Research shows all meditation practices are not the same. In recent studies these practices have been classified into three categories: Focused Attention, Open Monitoring, and Automatic Self-Transcending. Techniques in the Focused Attention category are techniques requiring concentration. Those forms of meditation show brain activity associated with focusing - fast EEG called gamma (20-50 Hz). Techniques in the Open Monitoring category include mindfulness or Vipassana. They are reported to activate brainwaves associated with internal mental processing - theta activity (4-8 Hz). Techniques in the Automatic Self-Transcending category transcend their own procedure - take the attention out of thinking, analyzing, controlling, or watching to a state of pure consciousness. The Transcendental Meditation technique is in this category. During TM synchronous alpha1 (8-10 Hz) activation is seen primarily in frontal executive areas as well as over the whole brain, indicating integrated functioning of the brain.
