This article explores the effects of stress on the brain, focusing on how challenge and concrete experience can turn off the CEO (conscious executive officer) of the brain. It discusses various brain activation patterns and consciousness states associated with different types of thoughts and meditation practices. The article also examines the impact of Transcendental Meditation (TM) on brain functioning and integration.

Brain Functioning during Simple and Choice Reaction Time Tasks
1st Task (Attention) In the first task, you'll see an * in the middle of the screen. Then you'll hear a tone. As soon as you hear the tone, press the space bar as fast as you can.
2nd Task (Remain Balanced) In this task, you'll see a number in the middle of the screen; then a blank screen for 1.5 seconds; and then a second number. If the first number is greater, press the left button. If the second number is greater, press the right button.
