How to Increase Brain Power 2

Brain power, and how to increase it, can be understood in two ways:

1. In terms of the energy supply to the brain under high work loads: how much fuel it can draw on without exhausing its computational power.

2. In terms of the processing capacity of the brain - how much information it can handle at once.

Brain power, neural signalling & energy supply

neuron energy: how to increase brain power The brain consumes 20% of our body's total energy supply but weighs only 2% of our body mass. It is highly energy-demanding. When the brain processes information, it is supplied with extra glucose and oxygen to maintain brain energy levels. When cognition places heavy demands on our fluid intelligence - such as during an exam, or in dealing with a complex problem - the workload is heavy and the brain may be temporarily fuel-limited. Natural brain reserves of the amino acid c reatine have been shown to play a central role in the biochemistry of supplying the brain with energy under high work loads. Creatine is naturally produced by the brain and improves brain metabolism. Like glucose and oxygen, creatine can help provide an increased fuel supply - with more efficiency - under heavy work loads.

Some important facts about the relationship between creatine and improving brain power are the following:

♦ Natural creatine levels in the brain increase as a result of brain training.
♦ Creatine brain supplementation has been shown in controlled trials to reduce mental fatigue and increase cognitive efficiency - reducing the need for oxygen in areas of the brain involved in doing mental calculations.
♦ As a brain supplement, 5 g of creatine monohydrate per day for 6 weeks increases the brain’s natural store of creatine by 9%. A carefully controlled study in 2003 led by Dr Caroline Rae at the University of Sydney has demonstrated that this level of supplementation resulted in a 40% gain (on average) in performance on a IQ demainding spatial intelligence task requiring high levels of fluid intelligence.

This effect has been explained by the authors as due to the fact it improves the cognitive efficiency of the brain through the key role it plays in brain energy metabolism. Essentially it helps brain cells (neurons) 'reset' quicker after they have sent messages to other neurons in neural circuits, thus improving speed and efficiency.

Dr. Rae and her colleagues state in their research paper

"Increasing the energy levels available for computation [in the brain]
increases the speed and power of computational resources, reflected
directly in improved general ability (intelligence)."
