It is normal to desire a higher level of cognitive functionality. After all, studies have proven that there is a link between intelligence and wealth, and there is no good reason to allow the genetic lottery to determine how successful you can become. With this in mind, many people turn to science to help them increase their IQ.

The Quest for Enhanced Cognitive Performance

Scientists have been studying brain functionality for centuries, but many of the most exciting developments have occurred within the past 60 years. At this point, we have a good understanding of each cognitive mechanism, and research has determined that nootropics and other cognitive enhancers can have a positive impact on our mental performance.

Most nootropics have been created in a lab as a synthesized version of a naturally occurring substance, and they enable us to temporarily hack our bodies to achieve higher levels of success. There are many educational resources that take a close look at the latest nootropics research, including the Peak Nootropics blog.

Cognitive Mechanisms

Our cognitive mechanisms determine how we perceive the world around us. Additionally, these mechanisms are integral in the learning process, and they impact our ability to memorize new data and make rational decisions. These mechanisms can be hindered by everything from a low IQ to a lack of sleep, but you can overcome some of these obstacles by turning to cognitive enhancers.

Understanding Neural Mechanisms


The prefrontal cortex makes it easier to focus on tasks at hand by using a process known as attentional control. In a nutshell, this means that your brain determines which task is likely to be the most important, and it amplifies this information to help you pay attention. However, some people naturally struggle with their ability to pay attention due to an underperforming prefrontal cortex.


Your memories are sorted into two categories: Declarative and nondeclarative. The distinction between these two is based on the type of memory that you are trying to store and recall. For example, facts that you learned in school are in your declarative memory, but your ability to please a woman in bed stems from the information within your non-declarative memory.


People learn in two different ways: Through interaction and observation. Studies have shown that the data we take in while we are learning a new task is stored in the prefrontal cortex. The type of learning that you undertake will determine if your memories will be sorted into the ventromedial prefrontal cortex or the dorsolateral prefrontal cortex. Either way, it is vital for your prefrontal cortex to be performing well if you want to retain a new skill.


Although we often think of focusing on something as being somehow separate from our general ability to pay attention, the two things are the same from a neural mechanism standpoint.

The Mechanism-Based Approach for Enhancing Cognition

As you can see, your brain relies on the proper functionality of each aspect of the prefrontal cortex. If any portion of this is not up to speed, you can experience difficulty with memory retention, learning and the ability to focus. Therefore, it makes perfect sense that you can also enhance your cognitive skills by directly targeting each desired neural mechanism.

Neuroenhancement – Using Neuroscience-Based Techniques to Enhance Cognitive Functions

Scientists have spent a lot of time looking for the best way to enhance cognitive functionality, and three things stand above the rest: Brain training, brain stimulation and medication or supplements such as nootropics.
Acting Directly on the Human Brain and Nervous System

Your nervous system can decrease your cognitive performance if you are suffering from certain illnesses or taking medication, so it makes sense to create the opposite effect with a cognitive enhancer. By targeting the brain and nervous system through neuroenhancement techniques, you can boost your mental and physical performance.

Altering the Properties and Performance of Your Brain

If you have difficulty with certain aspects of your cognitive functionality, it is likely that you have a deficit of some type. Nootropics can temporarily alter the properties of your brain, and this will result in increased performance. For example, Piracetam helps the AMPA receptor.

Standard Neuroenhancement Techniques

1. TMS:

Transcranial magnetic stimulation can be used to stimulate targeted areas of the brain in a non-invasive manner.

2. tDCS:

Transcranial direct current stimulation involves placing electrodes onto an individual’s head in order to send a low current to the specified area of their brain.

3. Neurofeedback:

Neurofeedback can be utilized to train a brain to have a higher level of functionality in regards to the regulation of bodily functions.

4. Behavioral Training Techniques

Neurobehavioral training can be used to help the mind and body in numerous ways. For example, this technique can help people with pain management by training the brain to turn down its pain signals.

Nootropic Drugs Revealed

What Exactly is a Nootropic?

Nootropics are typically derived from naturally occurring compounds, and they can have a very beneficial impact on your mental and physical functionality.

1. Nootropics Offer Non-Detrimental Benefits

These chemical substances have been designed to offer neuroenhancements without negatively impacting the brain. Therefore, the few side effects that have been reported from users are generally extremely mild.

2. Reported Enhancements

Nootropics have been linked by medical studies and users to a long list of enhancements, including increased memory retention and recall, logical reasoning skills, learning, creativity, concentration, mood and overall mental energy.

3. Chemical Structures of Nootropics

Nootropics feature a variety of chemical structures, depending on which type of cognitive enhancer you choose. For example, Piracetam is a derivative of GABA. Additionally, the base structure of this nootropic is the same as the rare amino acid pyroglutamic acid.

How Do Nootropics Work?

The Distinction between Different Nootropic Types

There are multiple nootropic families, including stimulants, neutraceuticals, and racetams. Although all of these nootropics are meant to provide a mental boost, they do work in different ways and offer various results.

1. The Hippocampus:

One of the most commonly targeted areas of the brain is the hippocampus. Some nootropics have been shown to facilitate long-term potentiation in the region, and this contributes to enhanced memory and learning skills.

2. Glucose Levels and Oxygenation:

Without the proper amount of oxygenation and glucose levels, your brain will begin to slow down its overall functionality. Some nootropics can temporarily elevate these levels, which leads to a cognitive boost.

3. Influence and Modulation of Brain Systems and Chemicals:

Nootropics have the ability to influence and modulate the chemical makeup in multiple brain systems. For example, the glutamatergic system is targeted by the glutamate receptors AMPA and NDMA. Certain nootropics are also known to affect the dopaminergic and serotonergic systems, and this impacts everything from mood to memory retention.
Understanding the Brain System

Developing a basic understanding of how each brain system works will make it easier to determine which nootropics are the right choice to suit your needs.

1. Acetylcholine and the Cholinergic System

Many nootropics target the cholinergic system because this has a big impact on your ability to learn, form and retain memories, make decisions, focus and have proper sensory perception. Acetylcholine is a neurotransmitter that works with the autonomic, central and peripheral nervous systems.

2. Glutamate and the Glutamatergic System

This system fulfills a crucial role in the health of your brain, and it is vital for learning and memory. Glutamate, which is also known as glutamic acid, is an amino acid and a neurotransmitter. Due to this, many people seek out a nootropic that targets the glutamatergic system.

3. Dopaminergic and Serotonergic Systems

Both of these systems control your overall feelings of happiness and pleasure. It should be noted that nootropics do not directly target these systems, but there are still some supplements that are known to elevate the user’s mood by having an impact on them.

Nootropic Effects and Mechanisms of Action

Before you can choose which nootropics to use alone or as part of a stack, you should take a few moments to review how each category of these supplements works within the human body.
