Answer 1

Answer: Findings where EEGs were used to measure brain activity in the motor cortex show that the subconscious activity preceded and influenced the conscious choice.

Explanation: It has been found from the repeated electroencephalogram tests conducted on the subjects that even before the brain consciously makes any decision, the subconscious influences it and the decision taken is thus not completely based on rational and subjective thought. The tests show that even though the brain registers an activity associated with conscious decision-making within 2/10th of a second, the motor cortex registers another activity even before a conscious decision is made by the brain.
