The brain is home to a variety of endogenous chemicals or neurotransmitters that are responsible for directing most of the acts of everyday life in regards to the brain. After traveling through a synapse to their respective receptor sites, these neurotransmitters transmit signals from one neuron to another within the brain.
Before taking the path of our neuroscientific friends with too much colloquial jargon, the most important concept to understand is that the brain is essentially a huge network of neurons that communicate through these neurotransmitters . Each type of neurotransmitter fills multiple functions in this chain from affecting the mood to memory formation. The theory holds that increasing the concentration of certain neurotransmitters or increasing the efficacy of certain receptors increases functionality. In other words, increasing levels of neurotransmitters associated with learning and memory should lead to improvement in desirable mental functions like concentration, mood elevation, and better memory.
Vasodilation And Oxygenation Of The Brain
Boosting vasodilation (widening of blood vessels) of the brain and inherently increasing blood and oxygen flow to the brain - are two essential elements for basic brain function. But we are talking about optimal and improved brain function. So let's raise the bets, yes?
Our brain consumes about 25% of the oxygen it takes, but only about 2% of our total body mass. That's a great oxygen weight ratio. In addition, the brain is supplied with blood carrying the necessary oxygen, energy (usually in the form of glucose), and nutrients.
It is not difficult to conclude that the theory is that by increasing the blood flow and oxygenation of the brain, we also increase mental capacity - if only in the short term. Think of an extra boost you need just before the big presentation or exam.
Increased blood circulation in the brain is also associated with alertness, better concentration, and improved mental stamina. Because good is not a bigger brain if not one that can keep up!
Conservation And Protection
The widespread spread of cognitive illnesses such as Alzheimer's and dementia have led to questions about environmental risk factors and their possible prevention. What causes these debilitating diseases? Can they be prevented?
Some nootropics are considered antioxidants with the ability to eliminate or otherwise regulate harmful substances in the brain. They are supplements that are associated with delaying the aging process of neurons, which in the world of nootropics translates to the possibility of slowing down - or even preventing - dissidence in those cognitive illnesses associated with old age.
The community of nootropic enthusiasts takes this a step further, raising the question of possible cognitive enhancement properties of these same supplements in healthy adults. Although it does not have the necessary scientific guarantees, everything indicates that in agreement with its effects in healthy adults it should in turn involve the prevention of this type of diseases at one level or another.
